3.4.4.1Switching ON
The GG864-2.4 switches on automatically each time the power supply is connected the first time or reconnected.
Note- When the power supply cable is disconnected, it is recommended to
wait approximately 5 seconds before applying the power again.
3.4.4.2Switching OFF
The GG864-2.4 can be switched off either by disconnecting the power supply or by software
command.
It is suitable a software switch-off command before disconnect the power supply cable.
Warning – Please note that hardware power off should be done only after
a proper GSM logoff. Any GSM device is request to issue a “detach”
request at turning off.
3.4.5Antenna
3.4.5.1Antenna Output
Warning – BEFORE connecting the GG864-2.4 to a power supply source, suitable
antennas shall be connected and properly installed.
The antenna has to be installed with care to avoid any interference with other electronic devices
and has to guarantee a minimum distance from the body (20 cm). in case this requirement cannot
be satisfied, the system integrator has to assess the final product against the SAR regulation.
For a good efficiency of the antenna and a minimum interference with other electronic systems, a
space of min. 40 cm around the radiating part should be left free of electrically conducting materials.
The less distance and the fewer obstacles between the SWS-GW antenna and the antenna of the
GSM/GPRS network base station, the less power is radiated by the gateway and the better signal
quality is achieved.
3.4.5.2Antenna Connectors
The GG864-2.4 includes two SMA bulkhead female, class 4 (2W) co-axial connectors for the two
external antennas.

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).
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

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.
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 26 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).
4.1.1.2SWS 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.

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.
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.

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 .
1 Byte
Variable
1 Byte
START
Message
STOP
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
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.

Table 4.1
4.3.2Message 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
Host
Gateway
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.

Status message for ACK is 0x01, status message for NACK is 0x02.

OpCode
BitMask

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. 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.

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 4.3.4.26). 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.
The following steps configure the PDA (this procedure can be done only one time):
•
Modify the Windows registry using NautizRegistry application: click on “start update”
•
Under Start/settings/connections/Bluetooth, choose the name associated to the incoming BT serial port
in order to enable it (by default COM0 is show but it is not enabled, it is enabled only choosing it again)

•
Now, SPP is configured. During AddBtHost, host can be registered by gateway:

•
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).

• 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.
• During functioning, if USB cable is connected, control interface on USB will be started in one
second. Old interface will be again active at the next reboot.
• To pass from control interface to transparent mode and vice versa takes at most one second.
• In order to put gateway in deep sleep, use Deep Sleep command (see 4.3.4.27). Gateway can
be woken up by user through wakeup button (controlled mode) or by RTC alarm (autonomous
mode).
• During autonomous mode, interface on GPRS is enabled: if gateway is turned on in controlled
mode and USB cable is unplugged, control interface is active on GPRS
• If reset button is pressed while gateway is going to deep sleep, system could reset two times
or go to deep sleep after a reset.

When it is woken up from RTC:
• If the USB cable is connected, gateway goes into controlled mode. Otherwise:
• state “Turning on SR and GSM”:
o SR and GSM modules are turned on in parallel from ARM9
• State “DXT communication and GSM registering”:
o gateway starts one wakeup session and then comm session, while GSM module is
registering to network
o gateway collects data from DXTs on the basis of Set Auto Dxt Data command (see
4.3.4.15)
o DXTs to be asked for data: all the active DXTs in the network or all the active DXT
present in the saved list (see 4.3.4.20, 4.3.4.21, 4.3.4.22)
o each comm slot will be stopped when gateway will receive the end of data DXT-frame
from each DXT
• state “SR off, FTP transfer and starting control interface on GPRS”:
o DXT communication is finished and SR is turned off
o FTP transfer: gateway connects to FTP server and sends one file with the format
described in 4.3.4.19. If a previous error has occurred, application log file is
automatically sent (see 4.3.4.31)
o While data file is sent to FTP server, control interface on GPRS is started (gateway is
the client, host is the server)
o FTP and GSM parameters are set by Set GSM parameters (see 4.3.4.7)
• State “Waiting for a command on GPRS control interface:”
o Once FTP transfer is finished, if a command is received within 45 seconds or had been
received during FTP transferring, gateway goes to controlled mode, otherwise it goes
back to deep sleep (next wake up time is automatically calculated on the basis of Set
GSM parameters - 4.3.4.7)
