4 SW Specification 4.1.1SW architecture In the following picture is depicted SW architecture of Gateway in both configuration1 (BG864-2.4) and configuration 2 (GG864-2.4).
Figure 13 Gateway SW architecture For detailed specification of the communication protocol see next paragraphs. 4.1.1.1SWS Gateway Application (Configuration 1 –no 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.
• 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.
Reproduction forbidden without Telit Communications S.p.A.
4.2 Host/gateway serial protocol The Host interacts with the SWS GW Application through a serial interface Sws Gateway Data Interface link Interface Control Interface Host Short Range Functionalities 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.
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. SWS Gateway Host Application Short Range Functionalities DXT Short Range Network Application 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.
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 START STOP OFFSET STUFF Value 0xab 0xcd 0x01 0xef Table 4.1 4.3.
4.3.3Command and Response messages Command and Response messages format is shown in the Figure 42. 2 Bytes 2 Bytes 1 Byte OpCode BitMask Reserved Variable Parameters 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.

USB interface is the default mode, so: • When gateway is turned at the first time, control interface on USB is started. • When USB cable is disconnected and USB interface is active, gateway waits for cable connecting. • If Set Gateway mode command (see 4.3.4.6) is sent during control interface, at the next boot the new interface will be active. • To pass from control interface to transparent mode and vice versa takes at most one second. • In order to put gateway in standby mode, use Standby command (see 4.
• Now, SPP is configured. During AddBtHost, host can be registered by gateway: Reproduction forbidden without Telit Communications S.p.A.
• In order to enable the control interface on BT, send setGatewayMode and Reboot commands: at the next reboot, if BT host is visible, gateway will open a serial connection with it (in this example, with the COM0 serial port). Reproduction forbidden without Telit Communications S.p.A.
6 Appendix: configuration 2 (GSM) controlled and autonomous modes Gateway in configuration2 stays most of the time in deep sleep mode and it can be woken up from RTC alarm o by wake up button. In the first case autonomous mode is activated while in the latest it goes directly in controlled mode. 6.
USB interface is the default mode, so: • When gateway is turned at the first time, control interface on USB is started. • When USB cable is disconnected and USB interface is active, gateway waits for cable connecting. • If Set Gateway mode command (see 4.3.4.6) is sent during control interface, at the next boot the new interface will be active. • At boot time, if USB cable is connected, control interface will be started always on the USB.
