The third pin in each of the connectors is not populated, and serves as a key for alignment. The connectors are mounted on opposite edges of the long axis of the mote.The M2135-1 and M2030-1 provide a bidirectional flow-controlled serial interface (serial protocol is specified in 7.3.1).The RST input pin is internally pulled up, and is optional. When driven active low, the mote is hardware reset until the signal is deasserted. Refer to section 6.1 for timing requirements on the RST pin. Note that the mote may also be reset using the mote serial command (see section 7.3.3.8).The TIME input pin is optional, and must either be driven or pulled up with a 5.1 MΩ resistor. Unless noted otherwise, all signals are active low.Table 9 M2135-1/M2030-1 Pin FunctionsPin Number Name Mote I/O Direction InternalPull Up/Down1GND -None2VCC -None3KEY (no pin) -None4RX In None5TX Out None6LED Out None7 M T_RTS Out None8MT_CTS Out None9SP_CTS In None10 TIME In None11 No Connection -None12 No Connection -None13 No Connection -None14 No Connection -None15 No Connection -None16 No Connection -None17 No Connection -None18 No Connection -None19 No Connection -None20 KEY (no pin) -None21 No Connection -None22 RST In 100 kΩ pull upFigure 2 M2135-1/M2030-1 Package with Pin LabelsPRELMINARY

InterfacesM2135-1/M2030-1 MOTE DATASHEET DUST NETWORKS™9CONFIDENTIAL6.3 Serial Interface Boot UpUpon mote power up, the MT_CTS line is high (inactive). The mote serial interface boots within boot_delay (see Table 14) of the mote powering up, at which time the mote will transmit an HDLC Mote Information packet, as described below in section 7.3.3.7. Note that full handshake (see 7.3.1.3) is in effect and is required to receive this packet.7.0 Interfaces7.1 TimestampsThe M2135-1/M2030-1 has the ability to deliver network-wide synchronized timestamps. The M2135-1/M2030-1 sends a time packet (as described in Table 42) through its serial interface when one of the following occurs:•Mote receives an HDLC get_parameter request for time/state (see Table 41)•Mote TIME signal is activatedThe TIME pin is optional and has the advantage of being more accurate. The value of the timestamp is taken within approximately a millisecond of receiving a TIME signal activation. If the HDLC request is used, because of packet processing, the value of the timestamp may be captured several milliseconds after receipt of the packet. The real time delivered to the sensor processor is relative to the real time clock on the Manager which serves as the network real time clock (NRTC). The time stamp skew across the network is guaranteed to be within ±250 ms of the NRTC.Figure 6 Real TimeWhen the time pin is activated for at least min_strobe_length (see Table 14), the mote responds by sending the time packet within 100 ms delay. Figure 7 Operation of Time Pin7.2 Status The M2135-1/M2030-1 provides an output signal driving a status LED. This LED displays network connectivity information and is used during mote installation. Alternatively, the mote’s network status may be polled via serial using the Get Parameter command (see 7.3.3.6) with the mote state parameter (see 7.3.4.3).Table 11 Status LED LED Appearance Mote StateOff Off, or in sleep modeSlow single blink (100 ms on, 900 ms off) On, and searching for potential networkSingle blink (100 ms on, 400 ms off) On, and attempting to join networkDouble blink (100 ms on, 100 ms off, 100 ms on, 700 ms off) On, connected to network, attempting to establish redundant linksSolid on On, fully configured into network with redundant parentsPRELMINARY
Interfaces10 DUST NETWORKS™M2135-1/M2030-1 MOTE DATASHEETCONFIDENTIAL7.3 Serial InterfaceThe M2135-1/M2030-1 offers a well-defined serial interface that is optimized for low-powered embedded applications. This serial interface offers a serial port comprised of the data pins (TX, RX) as well as the handshake pins (MT_RTS, MT_CTS, SP_CTS) used for bidirectional flow control. Through this port, the M2135-1/M2030-1 provides a means of transmitting and receiving serial data through the wireless network, as well as a command interface which provides synchronized time stamping, local configuration, and diagnostics. The following sections detail the Serial Interface Protocol, the Mote Command Interface, and the timestamping capability of the M2135-1/M2030-1 serial interface.7.3.1 Serial Handshake ProtocolThe Serial Interface Protocol handshake provides for flow control of packets transmitted via the M2135-1/M2030-1 serial interface. Packet delineation and error control are handled separately. The Interface supports the following: •Full-duplex communication•Bidirectional byte-level flow control7.3.1.1 Serial PortThe five-pin serial port is comprised of the data pins (TX, RX) as well as the handshake pins (MT_RTS, MT_CTS, SP_CTS) used for bidirectional flow control. This port supports 9600 bps operation in full-duplex mode. The handshake signals are active low.The following diagram illustrates the pins used in the handshaking protocol:Figure 8 Diagram of Pins Used in Handshaking ProtocolTable 12 Serial ParametersParameter ValueBit rate 9600 Start bit 1Data bits 8Parity NonePRELMINARY
InterfacesM2135-1/M2030-1 MOTE DATASHEET DUST NETWORKS™11CONFIDENTIAL7.3.1.2 Serial Interface Boot UpUpon mote power up, the MT_CTS line is high (inactive). The mote serial interface boots within 250 ms of the mote powering up, at which time the mote will transmit an HDLC Mote Information packet, as described below in section 7.3.3.7. Note that full handshake (see 7.3.1.3) is in effect and is required to receive this packet.7.3.1.3 Serial Interface Timing Requirements7.3.1.3.1 CTS Byte-level HandshakeThe following diagram shows generic CTS byte-level flow control timing. The following details are applicable to both MT_CTS and SP_CTS.Figure 9 CTS Byte-level Flow Control TimingTable 13 Pin UsagePin UsageRX, TX Used for serial data flow into and out of the mote.MT_RTS This signal goes active low when the mote is ready to send a serial packet. The signal stays low until the SP_CTS signal from the microcontroller goes active low (indicating readiness to receive a packet) or the ack_delay timeout (see Table 14) expires.SP_CTS SP_CTS should transition from high to active low in response to the MT_RTS signal from the mote.This indicates that the microcontroller is ready to receive serial packets. Following this, the microcontroller should strobe SP_CTS after receiving each byte. After all packets are received, the microcontroller should de-assert the SP_CTS signal.MT_CTS MT_CTS indicates the state of the network connection and availability of data buffers to receive packets destined for the network. Once the mote has established wireless network connection, it will use the MT_CTS pin to signify availability to accept serial packets for wireless transmission. At certain critical times during communication, the mote may bring MT_CTS high. MT_CTS will remain high if the mote does not have enough buffer space to accept another packet. It will also remain high if the mote is not part of the network. OEM designs must check that the MT_CTS pin is low before initiating each serial packet for wireless transmission. Note that the mote may receive diagnostic serial packets at any time regardless of the CTS state.Upon receipt of the first byte of the HDLC packet, the mote strobes MT_CTS in acknowledgement of each subsequent byte. After the last byte of the packet is received, MT_CTS switches back to signaling the availability of the network connection and data buffers. The microcontroller should wait a minimum of interpacket_delay (see Table 14) before initiating another packet transmission.The mote can accept diagnostics (packets that are not sent through the network) at any time, and the status of the MT_CTS pin may be ignored when initiating these packets. (MT_CTS will acknowledge each byte as specified in 7.3.1.3.1.TIME The TIME pin is optional and can be used for triggering a timestamp packet. For details, refer to 7.1.PRELMINARY
Interfaces12 DUST NETWORKS™M2135-1/M2030-1 MOTE DATASHEETCONFIDENTIALTimeouts T1, T2, and T3 are defined as follows (refer to Table 14 for values):•T1:interbyte_timeout—Maximum time between the transmit module sending a byte and the receiving module acknowledging the byte using CTS (requests the next byte)•T2: interpacket_delay—For communications into the mote, the minimum time after the mote receives the last byte of a packet before it can start receiving the next packet. For communications out of the mote, the minimum time between the mote receiving acknowledgement of the last byte reception (or timeout) and the mote driving RTS to request to send another packet.•T3: min_strobe_length—The minimum length of time that CTS must be held active to be recognized by the receiver.In idle mode or upon expiration of the interbyte_delay timeout, the transmit side treats CTS as level triggered (MT_CTS is disregarded in case of diagnostic serial packets). After transfer of the first byte of a packet, the meaning of CTS signal is changed to a byte acknowledgement strobe, active on a falling edge. In other words, CTS becomes a request signal for the next byte of a packet. This acknowledgement strobe will occur for all packets (both diagnostic and network packets). Whenever timeouts T1 or T2 occur, the packet is discarded and both sides switch to idle mode and start hunting for the next HDLC packet, assuming CTS active low. If a packet is transferred completely, the interbyte_delay after the last byte naturally takes care of switching to idle mode.7.3.1.3.2 Data Flow Out of the Mote Serial PortFigure 10 illustrates the process the mote uses to transmit serial data: 1. The mote ensures the interpacket_delay time has passed since the last transmission.2. The mote drives MT_RTS to active, waits for a falling edge on SP_CTS. Timeout is defined as ack_delay, and is long enough to handle the worst case response.3. If the mote times out before the SP_CTS becomes active, the mote restores MT_RTS to inactive and drops the packet.4. If SP_CTS is active, then the mote transmits the first byte and follows the CTS byte-level handshaking rules for subsequent bytes. 5. MT_RTS is restored to inactive after the ack_delay timeout has expired. Figure 10 Packet Transmission from Mote7.3.1.3.3 Data Flow into the Mote Serial PortFigure 11 illustrates the process the mote uses to receive serial data:The mote may receive serial packets for local commands (not intended for wireless transmission) at any time regardless of the MT_CTS status. The mote signals its readiness to receive serial packets for wireless transmission (serial payload command 0x80) by driving MT_CTS active low. The mote will drive MT_CTS low within interpacket_delay time after the transmission of the last packet. Figure 11 Packet Transmission to MotePRELMINARY

All packets between the microcontroller and the mote are encapsulated in the HDLC format (RFC 1662) and have the following structure. The command type indicates which API message is contained in the message content. The message content for each command type is described within the following sections.The frame checksum (FCS) is calculated based on the 16-bit FCS computation method (FCS-16, RFC 1662). The mote checks the FCS and drops packets that have FCS errors. There is no mechanism for the mote to tell the microcontroller that a packet has been discarded, so the applications layer must implement reliable delivery, if desired. All numerical fields in a packet are in big endian order (MSB first), unless otherwise noted. Section 7.3.5 provides an example of HDLC packet construction and HDLC packet decoding.Table 14 Timing ValuesVariable Meaning Min Max Unitinterbyte_delay The time between consecutive data bytes cannot exceed this time.0 7 msinterpacket_delay The sender of an HDLC packet must wait at least this amount of time before sending another packet.N/A 20 msack_delay The max time delay between the MT_RTS and the receivers acknowledge, SP_CTS. 0500 mstime_ack_timeout The mote responds to all TIME pin activation requests within this time.N/A 100 msdiag_ack_timeout The mote responds to all requests within this time.

The network uses this command to send data out through the mote serial interface. Upon receiving this packet from the network, the mote forwards it to the microcontroller and sends an acknowledgement back to Manager. The format of the serial packet payload is transparent to the mote. The maximum length of the payload is 80 bytes (excluding byte-stuffing bytes). The microcontroller receives exactly one copy of the message that was sent through the network.7.3.3.4 Command 0x84 Time/State Packet Time data packets use the command type 0x84. The time packet includes the network time and the current real time relative to the Manager. The mote sends this response when it receives a “get request” with “time” parameter (described later) or when the TIME pin is strobed high to low for minimum of min_strobe_length, as defined in Table 14. Usage of the TIME pin is described in section 7.1.7.3.3.5 Commands 0x87 and 0x88 Set Parameter Request/ResponseThe Set Parameter command allows the setting of a number of configuration parameters in the mote.

(All values are in hexadecimal.)Step 1 Define HDLC packet payload:Command type => 87Parameter => 01Network ID => 7DStep 2 Calculate FCS:a. Calculate the FCS using FCS-16 algorithm (RFC 1662) on the hexadecimal sequence '87 01 00 7D'. The FCS (including 1's complement) is 74 2F.b. Append FCS to payload, FCS is sent least significant byte first (RFC 1662):Step 3 Perform byte stuffing.To perform byte stuffing, check the HDLC Packet Payload and FCS for instances of “7D” or “7E” and replace as follows:7D => 7D 5D7E => 7D 5ENote that the additional control bytes do not count against the 80-byte payload limit.Step 4 Add start and stop delimiters:Enclose the above in start/stop flags (RFC 1662).Or simply, the hexadecimal sequence:7E 87 01 00 7D 5D 2F 74 7EExample 2: Decoding an HDLC packet received from the moteTo understand how to decode an HDLC packet sent from the mote, let’s assume that the mote received a “get mote information” command, and replied with the following HDLC Packet.
