11 ProBee-ZE20S Series User Guide Rev.0.12 Getting Started Creating a ZigBee network using the ZE20S modules consists of the following steps: • Install the ZE20S module on the development board • Create a ZigBee network by configuring a ZE20S module as the coordinator • Configure ZE20S modules as routers. This step is optional since the coordinator works as a router too. • Configure ZE20S modules as end devices • Transmit data between ZE20S devices This chapter describes how to install the ZE20S modules on to the development boards and how to use terminal software programs to access the ZE20S modules using AT commands for configurations and operations. The rest of the steps including ZigBee network creation, coordinator/router/end-device configurations and data transmissions are described in the following chapters. The more detailed information on the development kit and the configuration examples are also provided in the later chapter. 2.1 Hardware Installation 2.1.1 Development Board Layout Figure 2-1 shows the layout of the development board. The development board provides the interface between the ZE20S and the external serial port or USB port together with input/output terminals for convenient tests. TBD Figure 2-1 Development Board Layout
12 ProBee-ZE20S Series User Guide Rev.0.12.1.2 Antenna Installation The ZE20S starter kit includes the several antennas for evaluation purposes. You can try different antennas for testing purpose and select the appropriate antenna for the actual applications. Figure 2-2 shows how to install the RP-SMA dipole antenna to the ZE20S module. TBD Figure 2-2 RP-SMA Dipole Antenna Installation 2.1.3 Module Installation on the Development Board Once the antenna is installed on the ZE20S module, the ZE20S module can be installed on the development board. TBD Figure 2-3 ZE20S Installation on the Development Board
13 ProBee-ZE20S Series User Guide Rev.0.12.1.4 Serial/USB Cable Installation After the ZE20S is securely installed on the development board, please connect the included serial cable between the development board and your computer so AT commands can be sent from the computer to the ZE20S module. The serial port of the development board is DB9 male as a DTE terminal, and the serial cable included is a cross-over cable for DTE-DTE connection. To use the serial port, the HOST (SW2) switch should be set to UART. TBD Figure 2-4 Serial Cable Installation In case the serial port is not available for the computer, you can use the USB port of the development board instead. In this case, the internal USB-RS232 converter of the development board will convert the USB signal to the RS232 signal and vice versa. To use the USB port, the HOST (SW2) switch should be set to USB and the software driver for the USB in the CD should be installed on the computer. For the USB driver installation, please refer to the section 2.1.6. TBD Figure 2-5 USB Cable Installation
14 ProBee-ZE20S Series User Guide Rev.0.12.1.5 Powering Development Board Once all the installations are completed, please plug in the power connector using the included DC power adapter. The RS_PWR, USB_PWR and BATT_EN jumpers should be all OPEN to use the DC power adapter. Alternatively, the development board can be powered using batteries, or from the USB port or through the RS232 port pin 9. In these cases, the power source jumpers should be set accordingly. For details about the power source jumper settings, please refer to the section 6.3.1 Power. TBD Figure 2-6 Plugging DC Power Adapter 2.1.6 USB Driver Installation In case the USB interface is used for the communication between the development board and the computer, the corresponding software driver needs to be installed on the computer. Windows XP and later versions already include the USB driver. When Windows asks for the location of the USB driver, you can select the option to “install the software automatically” as shown in Figure 2-7. You can also choose to install the driver from the CD included if the driver is not installed correctly for some reason. Figure 2-7 USB Driver Installation
15 ProBee-ZE20S Series User Guide Rev.0.12.2 Using Terminal Software for AT Commands Once the hardware installation is complete, the ZE20S unit is ready to communicate with the computer using the AT commands using a terminal emulation software. You can use any kind of terminal emulation software. This document assumes HyperTerminal is used. If you are using Windows Vista or 7, HyperTerminal is no longer included in the Windows so you need to download HyperTerminal from the Internet. For more details on HyperTerminal, please refer to Microsoft web page. Once the HyperTerminal is installed, launch HyperTerminal and select the serial port that is connected to the ZE20S development board and enter the serial settings to use. The default serial settings of the ZE20S are 9600 bps, 8 data bit, none parity, 1 stop bit, hardware flow control. Figure 2-8 HyperTerminal Serial Settings
16 ProBee-ZE20S Series User Guide Rev.0.1To display the AT commands that are being typed, you need to enable the local echo option on the HyperTerminal. To enable this option, Go to File->Properties->Settings->ASCII setup and select the “Echo typed characters locally” option. To verify the connection, type AT and press the Enter key. If the AT command is accepted by the ZE20S, OK string will be displayed on the screen. Figure 2-9 Testing AT Command on HyperTerminal
17 ProBee-ZE20S Series User Guide Rev.0.12.3 Using ProBee Manager for Configuration Figure 2-10 ProBee Manager It is possible to set or get the configurations of the ZE20S using ProBee Manager. This PC utility helps that a user can configure several setting values easily without a terminal program and upload the firmware file to local and/or remote node.
18 ProBee-ZE20S Series User Guide Rev.0.13 ZigBee Network Configuration A ZigBee Network consists of a coordinator, routers and end devices. A minimal ZigBee network consists of one coordinator and multiple end devices which directly connect to the coordinator. For larger ZigBee networks, routers are required to provide redundant routings to form mesh networks. • ZigBee Coordinator: The coordinator forms the root of the network tree and might bridge to other networks. There is exactly one ZigBee coordinator in each network since the coordinator starts the ZigBee network itself. It also stores information about the network, including acting as the Trust Center & repository for security keys. • ZigBee Router: The routers are able to route messages between other devices. Since the coordinator provides the routing functionality too, the routers are optional to form a ZigBee network. • ZigBee End Device: The end device contains just enough functionality to talk to the parent node which is either the coordinator or a router. It cannot relay data from other devices. • ZigBee Sleepy End Device: The sleepy end device is the same with normal end device except it can stay in the sleep mode much longer. This relationship allows the end device to sleep significant amount of the time and achieve the long battery life. The ZE20S can be configured to work either as a coordinator, a router or an end device. Once the operation mode of the ZE20S is selected, corresponding parameters need to be set up appropriately. This chapter explains how to configure the ZE20S operation mode and other parameters related to the ZigBee network itself. Table 3-1 ZigBee Node Types Node Type Recommendation when to use ZE20S Coordinator It should be selected when it is first time to establish the network. Router It is recommended when there is a network already and it needs to be expanded. A router is suitable for fast and stable data transmissions and receptions. End Device It is recommended when it doesn’t need to expand the network anymore and there are enough nodes as parents. An end-device consumes less power than a router. Sleepy End Device It is recommended when the data transmissions occur rarely and in very small quantities. A sleepy end device can lose data if sleep duration is too long, but it is possible to consume extremely low power as low as 2uA. 3.1 Setting up ZE20S as a Coordinator A coordinator relays messages and can act as a parent to other nodes. Every personal area network (PAN) must be started by a node acting as the coordinator. This device is normally always powered on. To set up the ZE20S to work as the coordinator, please follow the steps as below
19 ProBee-ZE20S Series User Guide Rev.0.1• Configure the ZE20S node type as the coordinator • Optionally, select the channel mask. Otherwise, the ZE20S will use the default channel mask. • Optionally, set up the PAN ID and/or the extended PAN ID. Otherwise, the ZE20S will generate the PAN ID and/or the extended PAN ID automatically. • Permit joining when other router or end device tries to join the ZigBee network. 3.1.1 Node Type Selection for Coordinator The ZE20S module can be configured as a ZigBee coordinator by the AT command as below: AT+NODETYPE=n or AT+NT=n Where n is 0 = none, 1 = coordinator, 2 = router, 3 = end-device, 4 = sleepy end-device After the operation mode is selected, ATZ command should be performed to reset the unit to have the change applied. Example) AT+NODETYPE=1<CR> # Set node type as the coordinator OK<CR> # Response ATZ<CR> # Apply the change OK<CR> # Response 3.1.2 Channel Mask Configuration for Coordinator When the ZigBee coordinator starts, it scans predefined frequency channels to find the best frequency channel to use without causing interference with other wireless devices. The user is able to specify the channels to use with the AT command as below: AT+CHMASK=n Where n = channel mask to use. Default = 0x03FFF000 This value has a 32-bit hexadecimal unsigned integer. Each bit represents whether a channel will be used or not. For example, to use a channel between 12 and 15, the 12, 13, 14 and 15 bits of the channel mask should be 1 and all other bits should be 0. The default setting is 0x3FFF000 which means that all the channels from 12 to 25 can be used. The ZE20S supports only the channels between 12 and 25, so 0~11 bits and 26~31 bits should be 0. Table 3-2 shows the bit mask for each channel.
20 ProBee-ZE20S Series User Guide Rev.0.1Table 3-2 Channel Bitmask Channel 12 13 14 15 16 17 18 Bit mask 00001000 00002000 00004000 00008000 00010000 00020000 00040000 Channel 19 20 21 22 23 24 25 Bit mask 00080000 00100000 00200000 00400000 00800000 01000000 02000000 3.1.3 PAN ID Configuration for Coordinator Every ZigBee network should be assigned a PAN ID to identify the network. If the PAN ID is 0000, the ZE20S will generate a random 16-bit PAN ID to start the ZigBee network. Otherwise, the user can enter the PAN ID using the AT command as below: AT+PANID=xxxx Where xxxx is PAN ID to use. For example, 12AB. Default setting is 0000 When choosing a PAN ID, the user needs to make sure that there is no ZigBee network using the same PAN ID. If the PAN ID is already used by another ZigBee network, the PAN ID is unavailable and the user should choose a new PAN ID. In order to avoid this, PAN ID auto-generation is strongly recommended. The user can also assign the 64-bit extended PAN ID to the ZE20S using the AT command below. If the extended PAN ID is 0000000000000000, the ZE20S uses its IEEE address as the extended PAN ID. The extended PAN ID cannot be shared with other ZigBee networks either. AT+EPID=xxx…xxx Where xxx…xxx is EPID to use. For example, 0123456789ABCDEF. Default setting is 000…000. 3.1.4 Permit Joining When a router or an end device tries to join the ZigBee network, there should be at least one coordinator or router which is permitting joining. If there is no router in the ZigBee network yet, the coordinator should permit joining. The ZE20S provides three ways to permit joining are as follows: • Permanently permitting by configuration • Transiently permitting by AT command • Transiently permitting by digital input signal If joining is permanently permitted, any device can join anytime. Since this will allow even an unidentified device to join the network anytime, this mode should be selected with extra caution. The AT command to permit joining permanently is as follows: AT+PERMIT=255 or AT+PJ=255
21 ProBee-ZE20S Series User Guide Rev.0.1The user can permit joining for a moment at need. The AT command to permit joining is AT+PERMIT=n or AT+PJ=n Where n is the duration to permit in seconds ranging 1~254 seconds. The user can also configure the ZE20S to permit joining when the digital input GPIO0 is active. The AT command to enable this functionality is as follows: AT+GPIO0=5 or AT+IO0=5 When the ZE20S detects falling edge of the GPIO0, the ZE20S permits joining for the duration that is configured in S-register 22 (S22). The AT command to change the duration is as follows: ATS22=n Where n is the duration to permit in seconds ranging 1~254 seconds. Default is 60. S22 value determines the time that the device will allow other devices to join to it. If set to 255, the device will always permit other nodes joining. If the user reboots the coordinator (or a router), the device allows other nodes to join the network for the period defined by S-register 22. Note: When a device that has joined a network reboots, the device is able to join the network regardless of permitting. But, after the device has joined other network, rejoining the previous network should be permitted by the coordinator or a router. 3.2 Setting up ZE20S as a Router A router is a full-function routing device that relays messages and can act as a parent to other nodes. These devices must be always powered on. To configure the ZE20S as a ZigBee router, please follow the steps below. • Configure the ZE20S node type as a router. • Optionally, select the channel mask. Otherwise, the ZE20S will use the default channel mask. • Optionally, set up the PAN ID and/or the extended PAN ID. Otherwise, the ZE20S will scan and join the ZigBee network found automatically. • Permit joining when other router or end device tries to join the ZigBee network. 3.2.1 Node Type Selection for Router The ZE20S module can be configured as a ZigBee router by the AT command as below: AT+NODETYPE=n or AT+NT=n Where n is 0 = none, 1 = coordinator, 2 = router, 3 = end-device, 4 = sleepy end-device
22 ProBee-ZE20S Series User Guide Rev.0.1After the operation mode is selected, ATZ command should be performed to reset the unit to have the change applied. Example) AT+NODETYPE=2<CR> # Select router mode OK<CR> # Response ATZ<CR> # Apply the change OK<CR> # Response 3.2.2 Channel Mask Configuration for Router When the ZE20S as a ZigBee router or a ZigBee end device tries to join, it scans all the channels configured by channel mask to find the ZigBee network to join. The channel mask of router or end device should include the channel on which the coordinator is operating. For example, we assume that the coordinator of the network to join is operating on channel 12. The router or end device trying to join should has a channel mask of which 12th bit is 1 3.2.3 PAN ID Configuration for Router The PAN ID of a ZigBee router or a ZigBee end device should be the same with the PAN ID of the ZigBee coordinator. If the coordinator is using a randomly generated PAN ID, the user can get the operating PAN ID by running the AT command below on the coordinator: AT+OPPANID If the PAN ID of a ZigBee router or a ZigBee end device is 0000, the PAN ID is ignored. After checking the PAN ID, the ZE20S trying to join compares the extended PAN ID to make sure whether the network is the right network to join. If the extended PAN ID is the same with its configured extended PAN ID, it will try to join the network. Otherwise, it will try to find another network. The user can get the operating extended PAN ID by running the AT command below on the coordinator: AT+OPEPID If the extended PAN ID of a ZigBee router or a ZigBee end device is 0000000000000000, the extended PAN ID is ignored 3.2.4 Permit Joining The ZigBee router is configured and works the same way with the coordinator to permit joining of other nodes. Please refer to the section 3.1.4 Permit Joining for the configuration.
23 ProBee-ZE20S Series User Guide Rev.0.13.3 Setting up ZE20S as an End Device An end device is a leaf node which communicates only with its parent node and will not relay messages directly. To configure the ZE20S as a ZigBee end device, please follow the steps below. • Configure the ZE20S node as an end device • Optionally, select the channel mask. Otherwise, the ZE20S will use the default channel mask. • Optionally, set up the PAN ID and/or the extended PAN ID. Otherwise, the ZE20S will scan and join the ZigBee network found automatically. • Configure the poll timeout and the poll period Please refer to the section 3.2 Setting up ZE20S as a Router for the AT commands regarding the node type selection through the PAN ID configurations. When an end device joins the network, the power LED blinks periodically if GPIO1 is set to specific functionality. The end device belongs to a parent node which is either the coordinator or a router, and the parent node registers the end device to its internal child table for message relaying. This table is maintained as long as the end device polls the parent node periodically within the poll timeout value of the parent node. If the end device does not poll for the poll timeout value of the parent node, the parent node removes the end device from its child table and does not relay the message any more. Hence, the poll period of the end device should be equal or shorter than the poll timeout of the parent node to avoid accidental removal of the end device from the parent node’s child table. The ZE20S poll interval can be configured by setting the S-registers using the AT commands as below. ATS51=n, where n is poll timeout in seconds and the default is 60. ATS56=n, where n is poll period in seconds and the default is 5. End device polls the parent node at poll period defined by S56 periodically. It is for the connection to the parent node and data transmission with other nodes in the network. Even though the end device needs to poll the parent node continuously, it does not go into the sleep mode and it can send and receive messages any time unlike the sleepy end device. 3.4 Setting up ZE20S as a Sleepy End Device A sleepy end device can turn off radio to save power. To configure the ZE20S as a ZigBee sleepy end device, please follow the steps below. • Configure the ZE20S node as a sleepy end device. • Optionally, select the channel mask. Otherwise, the ZE20S will use the default channel mask. • Optionally, set up the PAN ID and/or the extended PAN ID. Otherwise, the ZE20S will scan and
24 ProBee-ZE20S Series User Guide Rev.0.1join the ZigBee network found automatically. • Configure the settings for sleep interval. Please refer to the section 3.2 Setting up ZE20S as a Router for the AT commands regarding the node type selection through the PAN ID configurations. One of the unique features of the ZigBee device is its extreme low power consumption which is mainly achieved by its efficient sleep and wake-up mechanism. While ZigBee coordinator and routers are required to be in operation always, ZigBee sleepy end devices can be configured to be in the sleep mode most of the time and only wake up at pre-configured time interval for data transmission before it goes into the sleep mode again. The ZE20S sleep interval can be configured by setting the S-registers using the AT commands as below. ATS51=n, where n is poll timeout in seconds and the default is 60. This value is for a parent node. If an end device does not send a poll request to its parent coordinator or router within the poll timeout, the end device is removed from the child table. Unlike the non-sleepy end device, sleepy end device does not use S51 as the poll period. Instead, it uses S53 as the sleep duration which works similar to the poll period, except it goes to sleep mode. ATS53=n, where n is sleep duration in quarter seconds and the default is 8. The ZE20S sleeps at sleep duration and turns off radio. ATS52=n, where n is poll period in milliseconds and the default is 100. Sleepy end device wakes up from the sleep mode if S53 timer expires or GPIO0 interrupt is generated or serial data is received. Once the sleepy end device wakes up, it polls the parent node at poll period defined by S52 until it goes to sleep mode again. Since the sleepy end device exchanges data with the parent node only by polling, S52 poll period is usually configured as around 100 ms. ATS54=n, where n is standby timeout in seconds and the default is 5. If there is no RF data or serial data for S54 seconds, the sleepy end device goes to sleep mode again. If any serial or RF data is sent or received, the timer will reset and the sleepy end device waits for another S54 seconds before it goes to sleep mode again. ATS55=n, where n is rejoin timeout and the default is 10. When the connection to the parent node is broken for S55 in seconds, the child node tries to rejoin the current network.
25 ProBee-ZE20S Series User Guide Rev.0.1 Figure 3-1 Sleep Interval and Wake-up Timing The sleepy end device can also wake up from the sleep mode by GPIO0 interrupt or incoming serial data. Once it wakes up, it also polls with the parent node at S52 interval and goes into sleep mode after S54 time elapses after the last data exchange. Note: If the sleepy end device wakes up by incoming serial data, the integrity of the first incoming byte is not guaranteed. It is strongly recommended to wake up the sleepy end device by using GPIO0 first before sending the serial data or use higher level serial data protocol to check the data integrity. 3.5 ZigBee Security Security is a major concern in the ZigBee architecture. Although ZigBee uses the basic security elements in IEEE 802.15.4 (e.g., AES encryption & CCM security modes), the ZE20S increase the security level with: • 128 bit AES encryption algorithms • Strong, NIST-approved security • Defined Key Types (Link, Network) • Defined Key setup and maintenance • CCM (Unified/Simpler mode of operation) • Trust Centers Poll Request Data Exchange Parent Node Sleepy End Device Sleep Wake-Up Sleep S53 S52 S54
26 ProBee-ZE20S Series User Guide Rev.0.13.5.1 Security Level In order to use security in the application, a user should set security level using the AT command below. Set 1 defines both Authentication and Encryption at the network layer. Set 0 defines no security. Disabling security in the application is not ZigBee compliant. All nodes in the network should have the same security level setup. The security level is configured using the AT command below. AT+SECURITY=n, where n is encryption level. (0=disable, 1=enable) 3.5.2 Link Key The trust center (normally coordinator in network) requests link key before a device is trying to join network. If link key the device has is wrong, joining process will be denied. Hence, all nodes in the network should have the same link key setup before joining the network. AT+LINKKEY=xxx…xxx, where xxx…xxx is 128-bit hexadecimal trust center link key. Default is FFF…FF. 3.5.3 Network Key It is the network-wide key used to secure transmissions at the Network Layer. The network key encrypts all transmissions at the Network Layer. The network key only needs to be set up for the coordinator. AT+NWKKEY=xxx…xxx, where xxx…xxx is 128-bit hexadecimal network key. Default is FFF…FF. 3.5.4 Update Key A trust center can update the Network Key to help minimize the risk associated with a particular instance of the network key being compromised. Key updates are broadcast by the trust center throughout the network, encrypted using the current network key. Devices that hear the broadcast will not immediately use the key, but simply store it. Later, a key switch is broadcast by the trust center to tell all nodes to start using the new key. At a minimum, the trust center should allow adequate time for the broadcast of the new key to propagate throughout the network before switching. AT+UPDATEKEY<CR>
27 ProBee-ZE20S Series User Guide Rev.0.14 Data Transmission The ZE20S supports three different types of data transmissions: unicast, multicast and broadcast. Unicast is to transmit data to a specific ZigBee device. Multicast is to transmit data to a group of ZigBee devices that are assigned a specific group ID. Broadcast is to transmit data to all ZigBee devices (or specific type of ZigBee nodes if specified) in the network. There are also two different methods to transmit data to other device as below: • Command mode: It sends only one packet up to allowed payload length by a form of command. • Data mode: It is possible to send data consecutively until leave the data mode using “+++”. 4.1 Command Mode 4.1.1 Unicast Unicast transmissions are sent from a source device to a destination device. The destination device can be any ZigBee device in the ZigBee network. To specify the destination device, the ZigBee address of the destination device should be known. There are two different ZigBee addresses assigned to each ZigBee device. The 64-bit address is a unique device address assigned during manufacturing. The 64-bit address is also called IEEE address or extended address. The 16-bit address is assigned to the device when it joins a ZigBee network. The ZE20S can send unicast messages based on either 16-bit address or 64-bit address. The AT command for the unicast transmissions is as below: AT+UNICAST=<node_id>,<MSG><CR> Where <node_id> = 16-bit or 64-bit address, <MSG> = data to transmit The maximum payload of the message is 90 bytes (or 72 bytes under security enabled). If the message length exceeds the maximum payload, the message cannot transmit and the error message will be presented. 4.1.2 Multicast Multicast transmissions are sent from a source device to destination devices with the specific group ID. The group ID is assigned to the devices using the AT+GROUPID command. The AT command for the multicast transmissions is as below. AT+MULTICAST=<group_id>,<MSG><CR> Where <group_id> = group ID, <MSG> = data to transmit The data transmission range can be set using the AT commands below. Please refer to the 9 S-Registers for more details.
28 ProBee-ZE20S Series User Guide Rev.0.1ATS36=n, where n is the radius. ATS37=n, where n is the number of hops through nonmembers. 4.1.3 Broadcast Broadcast transmissions are sent from a source device to all devices in the ZigBee network. The AT command for the broadcast transmissions is as below. AT+BROADCAST=<MSG><CR> Where <MSG> = data to transmit The user can also specify the transmit range by changing the S35 register value as below. Please refer to the 9 S-Registers for more details. ATS35=n, where n is the broadcast range. ATS36=n, where n is the radius. 4.1.4 Sending Binary Data There are some characters, e.g. carriage return, line feed and back space, that are not allowed or have special meanings in command mode. In order to transmit these characters in command mode, these characters must be encoded in a command line. The special characters encoding table is shown in Table 4-1. Table 4-1 Special Characters Encoding Table HEX Abbreviation Glyph Encoded Description 00 NULL - \00 Null character 0D CR - \0D Carriage return 0A LF - \0A Line feed 08 BS - \08 Backspace 09 HT - \09 Horizontal Tab 7F DEL - \7F Delete 5C - \ \5C Control character for binary encoding For example, when sending abc<CR> with AT+BROADCAST command, the command should be as follows: AT+BROADCAST=abc\0D<CR> 4.1.5 Display Incoming Message S11 register determines whether incoming message will be presented or not in the command mode. In
29 ProBee-ZE20S Series User Guide Rev.0.1the data mode, on the other hand, incoming data is always displayed. To change the S11 register, please use the AT command as below: ATS11=<value><CR>, where <value> = 0 to hide incoming message, 1 to show incoming message. If user wants to display incoming message in command mode, S11 should be enabled. It is presented by a form of +<IEEE address>|<MSG><CR>. When displaying incoming messages in command mode, some characters are encoded in the same way with sending binary data as in Table 4-1. For example, when receiving abc<CR> from 0001950000000001, the displaying message is as follows: +0001950000000001| abc\0D<CR> 4.2 Data Mode If the data is too long to send using the command mode, Data Mode can be used instead. Once the ZE20S enters a Data Mode session, the ZE20S can send data continuously to a specific node or current network until the data mode is escaped. The data is packetized and transmitted at every inter-character timeout. This data link to the designated device is maintained until the escape command “+++” is entered. To return to the last data mode after the ZE20S is escaped by “+++”, use the AT command as below. ATO<CR> 4.2.1 Unicast Data Mode Unicast data mode can be used for continuous data transmission to a particular node. Unicast data mode can be entered using either ATD or AT+TRANSMITMODE=1 (or 4). If ATD command is used, the device will enter the unicast data mode immediately until escaped using “+++” or reset by ATZ. If the device is reset, it will not enter the unicast data mode in this case. On the other hand, if AT+TRANSMITMODE=1 (or 4) is used to enter the unicast data mode, the device enters the unicast data mode again whenever the device is reset. To disable the unicast data mode, escape the data mode first by using “+++” string and use AT+TRANSMITMODE=0 and reset the device to apply the setting permanently. AT commands used for the unicast data mode are as below. AT+DESTLA=<value> Set the destination address, where <value> is 64-bit IEEE address of destination node for unicast data mode.
30 ProBee-ZE20S Series User Guide Rev.0.1ATD<CR> Set unicast data mode to the preconfigured destination IEEE address without reset. ATD<value><CR> Set unicast data mode and <value> can be either 16-bit node ID or 64-bit IEEE address of remote node. AT+TRANSMITMODE=1<CR> Set the transmit mode to unicast to a destination IEEE address. The device should be reset to apply the mode. AT+TRANSMITMODE=4<CR> Set the transmit mode to unicast to a sink node. A sink node is determined if s-register 61 is set. The device should be reset to apply the mode.

Every ZE20S belongs to a certain group by predetermined group ID when form or join the network. Multicast data mode can be entered using either ATM or AT+TRANSMITMODE=2. If ATD command is used, the device will enter the multicast data mode immediately until escaped using “+++” or reset by ATZ. If the device is reset, it will not enter the multicast data mode in this case. On the other hand, if AT+TRANSMITMODE=2 is used to enter the multicast data mode, the device enters the multicast data mode again whenever the device is reset. To disable the multicast data mode, escape the data mode first by using “+++” string and use AT+TRANSMITMODE=0 and reset the device to apply the setting permanently. AT commands used for the multicast data mode are as below. AT+GROUPID=<value>, where <value> is 16-bit group ID for multicast data mode. Set Group ID of the device. The device will receive the multicast data sent to this Group ID. AT+DESTGROUPID=<value>, where <value> is 16-bit destination group ID for multicast data mode. Set destination Group ID of the device.

The destination address or group ID of the remote nodes is not necessary for broadcast data mode. The transmit range is determined by the S-register 35. Broadcast data mode can be entered using either ATB or AT+TRANSMITMODE=3. If ATB command is used, the device will enter the broadcast data mode immediately until escaped using “+++” or reset by ATZ. If the device is reset, it will not enter the broadcast data mode in this case. On the other hand, if AT+TRANSMITMODE=3 is used to enter the broadcast data mode, the device enters the broadcast data mode again whenever the device is reset. To disable the broadcast data mode, escape the data mode first by using “+++” string and use AT+TRANSMITMODE=0 and reset the device to apply the setting permanently.

35 ProBee-ZE20S Series User Guide Rev.0.15 Digital and Analog I/O 5.1 GPIO Configuration The ZE20S module has total 14 I/O pins. Among these pins, I/O pin 6 is assigned to factory reset only and the user can use the rest 13 pins for general purpose inputs and outputs. The I/O pin assignments are shown in Table 5-1. As shown in Table 5-1, some pins provide special functions built into the firmware. Table 5-2 describes the special functions tied to the specific pins. Table 5-1 Default I/O Pin Assignments (ZE20S) Pin Number GPIO Number Special Functions AI Enable The AT command below can be used to change the GPIO settings. AT+GPIO=<values><CR> or AT+GPIO<number>=<value><CR> Where, <values> is a number between 0~5 as explained below: 0 Disabled (unmonitored digital input) 1 Digital input, monitored 2 Digital output, default low 3 Digital output, default high 4 Analog input, single ended (only valid for GPIO3~6) 5 Reserved for pin-specific alternate functionalities (See Table 5-2)
36 ProBee-ZE20S Series User Guide Rev.0.1 Table 5-2 Special GPIO Pins Function GPIO# Type Description Factory_reset / Bootloader DI This input is dedicated for the factory reset button. If user wants to restore the ZE20S device settings to factory default, this input needs to be pressed for more than two seconds. It will be applied after the input released again. If this input is pressed while the ZE20S starts, the local node enters bootloader menu and it is possible to upload the firmware. Permit_joining / Wake-up DI This input (falling edge, i.e. High to Low change) is used to permit joining or interrupt sleeping. This function is activated when GPIO0 is set to 5. The functions depend on the node type of the ZE20S. If the node is set to coordinator or router, this input works to permit other nodes joining for S-register 22 value. If the node is set to sleepy end-device, it is used for wake-up signal when the node is sleeping. Power LED DO If GPIO1 is set to 5, this output turns ON (High) when power is supplied. If the node is set to an end-device, it will blink periodically. Please refer to 9 S-Registers for S14 regarding the management of the LED status. Status LED DO If GPIO2 is set to 5, this output turns ON (High) when the device joins a network, blinks when joining is permitted, and turns OFF (Low) when leaves the network. Please refer to 9 S-Registers for S14 regarding the management of the LED status. UART_CTS DI This input is used for UART CTS if GPIO8 is set to 5. It should be enabled when CTS flow control is used. UART_RTS DO This output is used for UART RTS if GPIO9 is set to 5. It should be enabled when RTS flow control is used. UART_DTR DO This output is used for UART DTR if GPIO10 is set to 5. UATR_DSR DI This input is used for UART DSR if GPIO11 is set to 5. 5.2 I/O Sampling The I/O status can be monitored and controlled using the local or remote AT commands. Also the ZE20S can be configured to sample the I/O status and send to a remote device periodically or at specific events. 5.2.1 Queried Sampling The I/O status can be monitored and controlled using the AT commands either locally or remotely.
