Telit provides Linux Operating system with all low level drivers needed in the SWS gateway: • GPIO • Serial • USB device And provides access for the main peripheral: • Bluetooth It is provided all sw to initialize and setup Bluetooth communication and access to the Bluetooth interface as a serial port where it is possible to send and receive data (SPP profile). • GSM/GPRS Communication with GSM/GPRS is provided through the serial port where it is possible send and receive data. • USB • ZE60 And to manage power modes. SWS Gateway application is a customization of Gateway application with the scope of export the serial protocol Interface to communicate with the external host. It: • Manages the gateway • Route messages between peripherals • Wake up and power up the peripherals at preprogrammed intervals

Autonomous gateway In this mode gateway is in standalone mode, without any external devices connected to it and communicates only via radio with DXT in the SR network, collecting data sent by each DXT in a log file stored in flash. Upload of log data files will be possible through specific command on serial protocol to retrieve the file (see Get Log file). Format of log files, naming convention and upload process have to be agreed with Alciom. 2. Slave mode In slave mode, gateway is connected to other device that acts as a master and controls the operations of the gateway. Other devices can be: • Fixed PC by USB connection
Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights Reserved page 27 of 73 • Mobile devices, as PDA, phone, field equipment, through Bluetooth connection or RS232 serial connection. In slave mode gateway supports communication protocol between host and gateway that has to be the same through all the interfaces: • USB • RS232 • Bluetooth • GSM/GPRS* (by socket connection- see sws gateway application conf 2) As all the interfaces can be seen as serial interfaces a serial protocol will be developed. All the interfaces will be available at the same time but communication will be with one of them at a time. A specific command will be developed to set the communication mode and to switch to another (see Set Gateway Mode command). 4.1.1.2 SWS Gateway Application (Configuration 2 – GSM) In this configuration two operating modes are possible: 1. Autonomous gateway( In this mode gateway is in standalone mode, without any external devices connected to it and communicates only via radio with DXT in the SR network, collecting data sent by each DXT in a log file stored in flash, and sending it at preprogrammed interval (once a day) through GPRS network to an FTP server. 2. Controlled mode In this mode, gateway is always connected to GSM/GPRS network , or always connected via USB or RS232 to the server and wait commands from it. In this mode all the command /answer should follow the serial protocol described in next paragraph. If GPRS/GSM connection is active, same protocol as described in next paragraph will be available through socket connection. .

Sws Gateway Short Range Functionalities Interface Data Interface Control Interface link Host 4.2 Host/gateway serial protocol The Host interacts with the SWS GW Application through a serial interface This serial interface is internally split into two interfaces: 1. Control (or management) Interface. This interface receives commands from Host and sends back information/responses. 2. Data Interface, that allows direct communication with DXT nodes joined to the SR network. Control and Data Interfaces are mutually exclusive, they can be used one at a time. 4.2.1.1 Data-mode If the data-mode is used, SWS Gateway is completely transparent. Data messages flow in both directions as a raw bit stream. Figure 7 – Gateway in data mode DXT SWS Gateway Short Range Functionalities Data Interface Control Interface Host DXT Short Range network DXT
The way data messages are used is totally user dependent. From a logical point of view the responsible for data managing are applications running on Host and each DXT connected to the gateway. Figure 8 – Data Mode: data flow at application layer 4.2.1.2 Command-mode If command-mode is used, the Host may send specific commands to SWS gateway in order to configure it. 4.3 Control Interface Once SWS GW Application has been started, the Control Interface will be available on the serial interface ( it can be RS232, USB or Bluetooth) The Control Interface receives from the Host the serial packets, converts them to internal control messages and sends the responses to the Host. All frame formats in this clause are routed in the order in which they are transmitted, that is, from left to right. For every field the left most byte is the least significant byte and the right most byte is the most significant byte (little endian). The serial packets shall be formatted as illustrated in Figure 9 . Figure 9 Every packet has a START byte and a STOP byte. 4.3.1 Stuff algorithm When using START and STOP bytes in the Message, it must be ensured that they will not be confused with the true START and STOP. To achieve this result, an escaping technique called “stuff Message STOP Variable 1 Byte 1 Byte START Short Range Network SWS Gateway Short Range Functionalities Application DXT Application Host
Reproduction forbidden without Telit Communications S.p.A. written authorization - All Rights Reserved page 31 of 73 algorithm” has to be used. Every time the Message field contains a byte equal to the START or the STOP, the same byte must be preceded by a STUFF byte and incremented of an OFFSET. Every time that in the Message field there is a byte equal to the STUFF byte it must be preceded by another STUFF byte. Values of START, STOP, STUFF and OFFSET bytes are shown in Table 4.1. Name Value START 0xab STOP 0xcd OFFSET 0x01 STUFF 0xef Table 4.1 4.3.2 Message protocol The message protocol is used by the Host to configure and to manage the SWS Gateway. It is an acknowledged protocol, so that every time the Host sends a command to the Control Interface of the Gateway, it will acknowledge the command with an ACK (Figure ). Therefore there are two types of messages: • Command/Response messages • ACK messages Gateway Host Command Ack Response Figure 10 If the Command do not respect the protocol or if its parameters are out of range, the Control Interface of the Gateway will send only a NACK (acknowledge with status set to ERROR) and no response. Gateway Host Command Nack Figure 11 ACK and messages are: 2 bytes 1 byte START Opcode Status STOP Status message for ACK is 0x01, status message for NACK is 0x02.
4.3.3 Command and Response messages Command and Response messages format is shown in the Figure 42. Figure 42 The OpCode is the code of the Command sent by the Host or the Response sent by the Gateway. The field BitMask explains which parameters are active in the Parameters field. Note that all the parameters are always present in the packet, so a specific Command/Response has always the same size. If a parameter is not active, the respective value will be not modified. If a parameter is mandatory and an invalid BitMask field has been set, command will be not executed. Default values will be loaded by Reset command. The field Reserved is ignored, and its value shall be set to 0xFF. The field Parameters holds the parameters of the command. It has a specific format for every command depending on the OpCode. Every parameter could be optional (O) or mandatory (M), if it is optional and the parameters is not enabled the Gateway will use a default value. Every response has a Status field. All the parameters of responses are mandatory. Every command has a 10 minutes timeout. When timeout expires and command is not executed yet, error response will be received. During execution of any command (after ACK message has been received and before response is received), only Get Status and Reboot commands can be executed; other commands or bytes on control interface are not considered. Table 4.2 shows the list of commands and responses.

Gateway will be woken up when a command is received on the active interface. • In the state (1), GW checks if there is a registered BT host device. In order to register a BT host device, use Add BT host command (see 4.3.4.34). • When GW is in the state (2), if host device is reachable and accepts serial communication, GW will be woken up from standby mode and launches CI on BT. • In order to turn off gateway, use Turn Off command (see 4.3.4.28). ARM led will turn off and switch can be moved to “OFF” position after 5 seconds. • If battery is too low and power supply from USB is not provided, gateway automatically turns off. 5.1 BT pairing using Windows Mobile If a host with Windows Mobile is used, it should be configured in order to export an incoming port on the BT serial profile.
