GL300 @Tracker Air Interface Protocol

1. Overview

1.1. Scope

The @Track Air Interface Protocol is a digital communication interface based on printable ASCII characters over SMS or GPRS which is used for all communication between the backend server and the terminal. The backend server sends a command to the terminal and then the terminal confirms with an acknowledgement message. If necessary, the terminal also sends report messages to the backend server. The purpose of this document is to describe how to build up the backend server based on the @Track Air Interface Protocol.

Figure 1: System architecture

The backend server can be accessed by many terminals and should have the following abilities:  The backend server should be able to access the internet and listen to the connection

originating from the terminal.

 The backend server should be able to support a TCP or UDP connection with the terminal. It

should be able to receive data from the terminal and send data to the terminal.

 The backend server should be able to receive and send SMS.

3. Message Description

3.1. Message Format

All of the @Track Air Interface Protocol messages are composed of printable ASCII characters. Each message has the following format:

Message format Message type

AT+GTXXX=<parameter1>,<parameter2>,…$ Command +ACK:GTXXX,<parameter1>,<parameter2>,…$ Acknowledgement +RESP:GTXXX,<parameter1>,<parameter2>,…$ Report

The entire message string ends with character ‘$’. The characters ‘XXX’ identify the deferent message. The “<parameter1>,<parameter2>,…” carry the message’s parameters. The number of parameters is different in different messages. The ASCII character ‘,’ is used to separate the neighbouring parameter characters. The parameter string may contain the ASCII characters: ‘0’-‘9’, ’a’-‘z’, ’A’-‘Z’. Detailed descriptions of each message format are located in the specific message sections.

By sending Commands to the terminal, the backend server can either configure and query the parameters of the terminal or control the terminal to perform specific actions. When the terminal receives Commands over the air, it will reply with a corresponding Acknowledgement message. According to the configuration of the parameters, the terminal can send Report messages to the backend server. Please see the following figure:

GL300 @Tracker Air Interface Protocol

When the device receives commands over the air, it supports several commands in one SMS or GPRS packet without separate symbol between two close commands. But it is necessary to make sure the total size of the several commands is not longer than 160 if the commands are sent via SMS. Here is an example to send three commands in one SMS.

AT+GTFRI=gl300,1,1,,,0000,2359,60,60,,,1F,0,,,,,,,,0007$AT+GTGEO=gl300,0,3,101.412248,

21.187891,1000,600,,,,,,,,,0008$AT+GTSPD=gl300,1,5,40,30,60,,,,,,,,,,,,,,,,0009$

It includes three commands (AT+GTFRI, AT+GTGEO and AT+GTSPD) in the above message. And the terminal will handle the three commands one by one after it received the message via SMS and it will report the following three acknowledgement message to the backend server one by one.

+ACK:GTFRI,1A0102,135790246811220,,0007,20100310172830,11F0$

+ACK:GTGEO,1A0102,135790246811220,,0,0008,20100310172900,11F1$

+ACK:GTSPD,1A0102,135790246811220,,0009,20100310172930,11F2$

3.2. Command and Acknowledgement

3.2.1. Quick Start Setting

The command AT+GTQSS is used to set the GPRS parameter and backend server information in one command if all these settings are within 160 bytes, otherwise use AT+GTBSI and AT+GTSRI in two steps.

 AT+GTQSS= Example:

AT+GTQSS=gl300,cmnet,,,4,,,116.226.44.17,9001,116.226.44.16,9002,+8613812341234,0,1, ,,0001$ Parameter Length (byte) Range/Format Default

Password 4 – 6 ‘0’ – ‘9’, ‘a’ – ‘z’, ‘A’ – ‘Z’ gl300 APN <=40 APN user name <=30 APN password <=30 Report mode 1 0 – 6 0 Reserved 0 Buffer enable 1 0|1|2 1 Main server IP/domain name

<=60

Main server port <=5 0 – 65535 0 Backup server IP <=15 0.0.0.0 Backup server port <=5 0 – 65535 0 SMS gateway <=20 Heartbeat interval <=3 0|5 – 360min 0 SACK enable 1 0|1 0 Reserved 0 Reserved 0 Serial number 4 0000 – FFFF Tail character 1 $ $

 <Password>: The valid character of password is ‘0’-9’, ‘a’-‘z’, ‘A’-‘Z’. The default value is

“gl300”.

 <APN>: Access point name (APN).  <APN user name>: the GPRS APN user name. If the parameter field is empty, the parameter

will be cleared.

 <APN password>: the GPRS APN password. If the parameter field is empty, the parameter

will be cleared.

 <Report mode>: Supports report modes as following:

 0: Stop reporting.  1: TCP short-connect preferred mode. The connection is based on TCP protocol. The

TRACGL300AN001 - 12 -

Queclink Confidential

GL300 @Tracker Air Interface Protocol

terminal connects to the backend server every time it needs to send data and will shut down the connection when the terminal finishes sending data. And if it is failed to establish a TCP connection with the backend server (including Main Server and Backup Server), it will try to send data via SM S.

 2: TCP short-connect forced mode. The connection is based on TCP protocol. The

terminal connects to the backend server every time it needs to send data and will shut down the connection when the terminal finishes sending data. And if it is failed to establish a TCP connection with the backend server (including Main Server and Backup Server), it will be stored in the BUFFER (if BUFFER function is enabled, please refer to <Buffer enable>) or discarded (if the BUFFER function is disabled).

 3: TCP long-connect mode. The connection is based on TCP protocol. The terminal

connects to the backend server and maintains the connection using the heart beat data. Please note that in this mode the backend server should respond to the heart beat data from the terminals.

 4: UDP mode. The terminal will send data to the backend server by UDP protocol. It

supports to receive protocol command via UDP. But it is recommended to make sure the IP address and UDP port of the device can be visited in the internet, and this is generally realized by heart beat package and the message +RESP:GTPDP.

 5: Force on SMS. Only use the SMS for transmitting.  6: UDP with fixed local port. Like the UDP mode, the terminal will send data using

UDP protocol. The difference is the terminal will use fixed local port rather than random port to communicate with the server in this mode. Thus the backend server could use identical port to communicate with all terminals if the backend server and the terminals are all in the same VPN network. The port number the device uses is the same as the port number of the primary server.

 <Reserved>: .Not used at present.Please keep empty  <Buffer enable>: Enable or disable BUFFER function. Please refer to 3.3.5 for the details

about BUFFER

function.

 0: Disa

ble the BUFFER function.

 1: Enable the BUFFER function.  2: High priority. Enable the buffer report function. Under this working mode, the

device will send all the buffered messages before sending any normal message except for the SOS message (+RESP:GTSOS).

 <Main server IP/domain name>: The IP address or the domain name of the main server.  <Main server port>: The port of the main server.  <Backup server IP>: The IP address of the backup backend server.  <Backup server port>: The port of the backup server.  <SMS gateway>: Maximum 20 characters including the optional national code starting with

“+” for SMS messages. Short code (for example: 10086) is also supported.

 <Heartbeat interval>: the interval for the terminal to send heartbeat package message to the

backend server. If set to 0, no heartbeat package is sent.

 <SACK enable>: A numeric to indicate whether the backend server should reply SACK

message to the device.

 0: the backend server does not reply SACK message after receiving a message from

TRACGL300AN001 - 13 -

GL300 @Tracker Air Interface Protocol

the device.

 1: the backend server should reply SACK message after receiving a message from the

device.

 <Serial number>: the serial number for the command. It will be invoked in the ACK message

of the command.

 <Tail character>: a character to indicate the end of the command. And it should be “$”.

Note:

If <Report mode> is set as 4 (UDP mode), it is strongly recommended to enable SACK or heart beat mechanism (<Heartbeat interval> doesn’t equal to 0).

The acknowledgement message of AT+GTQSS command:

 +ACK:GTQSS, Example:

+ACK:GTQSS,1A0102,135790246811220,,0001,20100310172830,11F0$ Parameter Length (byte) Range/Format Default

 <Protocol version>: The combination of the device type and the version number of the

applied protocol. The first two characters ‘XX’ indicate the device type. ‘1A’ represents GL300. The middle two characters are the main version number and the last two characters are the minimum version number. Both the main version and the minimum version are hex digital. For example, ‘020A’ means version 2.10.

 <Unique ID>: ID of the device, use the IMEI of the current SIM card inside the terminal.  <Device name>: Please refer to the parameter <Device name> in the command

AT+GTCFG.

 <Serial number>: The same serial number which is sent to the device with the corresponding

command. The backend server could use it to distinguish which command the ACK message is for.

 <Send time>: The local time to send the ACK message.  <Count number>: The self-increasing count number will be put into every acknowledgment

message and report message. The count is beginning from 0000 and increases by 1 every time. It will roll back after “FFFF”.

 <GPS fix delay>: This is the time to wait after GPS fixing succeed. After GPS fixing succeed,

the device will wait for a period of time (defined by <GPS fix delay>) and then get the result of GPS fixing because maybe it is not accurate to get the position immediately after GPS fixing succeed. (e.g. if <GPS fix delay> is set as 7, we will wait for 7 seconds after GPS fixing succeed and then get the position as the result). The range of the parameter is 5 – 60, and the default value is 5. Unit: second.

 <Report items mask>: Bitwise report mask to configure the composition of all the uplink

message. Each bit represents a field in the uplink message. If some bit is set as 1, the corresponding field will be filled if it is included in the uplink message. Otherwise, the field will be empty.

Bit0(0001): <speed> Bit1(0002): <azimuth> Bit2(0004): <altitude> Bit3(0008): GSM LAI and CI, including <mcc>, <mnc>, <lac>, <cellid> Bit4(0010): <send time> Bit5(0020): <Device name>

 <Event mask>: A Hex value to configure which event reports can be sent to the backend

server: Each bit corresponds to a report me ssage. And if the bit is set as 1, the correspo nding report message can be sent to the backend server. Otherwise, it can not be sent to the backend server. Here is the mapping between each bit and each report message.

bit0(0001): +RESP:GTPNA bit1(0002): +RESP:GTPFA bit2(0004): +RESP:GTEPN bti3(0008): +RESP:GTEPF bit4(0010): Reserved bit5(0020): +RESP:GTBPL Bit6(0040): +RESP:GTBTC Bit7(0080): +RESP:GTSTC bit8(0100): +RESP:GTSTT bit9(0200): Reserved bit10(0400): +RESP:GTPDP bit11(0800): +RESP:GTPNL bit12(1000): +RESP:GTIGN and +RESP:GTIGF bit13(2000): +RESP:GTIGL

it will consider the device is non-movement if the speed according to the GPS fixing result is slower than <movement speed> and the distance between the current GPS point and the last moving GPS point is less than <movement distance>. After it considers the device is non-movement, it will stop reporting FRI message after report FRI messages (speed field is shown as -1 in these messages.) for <movement send number> times.

 <movement speed>: The speed threshold of movement detect. The unit is km/h.  <movement distance>: The distance threshold of movement detect. The unit is meter.  <movement send number>: According to the speed threshold and distance threshold, if the

terminal is considered staying at one position, the terminal will send out at most this number of reports before it moves again.

 <corner>: A numeric to indicate whether to report +RESP:GTFRI message according to the

heading changing, i.e. the movement direction of the device changing. 0: disable the function, i.e. do not detect whether the device has changed its direct io n. 1 – 180: The angle used for deciding whether the device turn around. If the heading changing is greater than the specified value, the device will be considered tur ni ng around. Unit: degree.

Note:

 Check interval

If <GPS On Need> was set as 1 or <GPS On Need> was set as 2 without ignition on, The terminal has two modes to operate the GPS module according to the value of <Check interval>:

 Mode 1: If the <Check interval> is more than 60 seconds, the terminal will close the

GPS part every time after GPS fixing finishes in order to save power.

 M

ode 2: If the <Check interval> is le ss than 60 seco

nds, the terminal will never close

the GPS part in this mode.

Due to the maximum length limitation of the report message, it must be assured that: <Send interval> / <Check Interval> <= 15. If exceed that limitation, the command is discarded and the previous settings keep untouched.

If the terminal is in “Force on SMS Mode” (<Report mode> = 5) while the <Send interval> / <Check Interval> > 1, the terminal will report only the last position in the fixed timing report, because only one position could be filled in one single SMS message (160 bytes at most).

 Action time range

 <Begin time> < <End time>: reports in the time period (begin time, end time) every day.  <Begin time> > <End time>: reports starting from <Begin time> and stopping at <End

time> on the following day.

 <Begin time> = <End time>: reports on the whole day.

 Scheduled Report Mode

For the mode schedule distance report and scheduled mileage report and optimum report, <GPS on need> must be 0 (Never close GPS chip) or 2 (Never close GPS chip in ignition on state or movement state) for the function. For the mode scheduled timing report, it doesn’t care whether GPS works always.

 Corner report

It is necessary to set <GPS on need> as 0 or 2 for detecting turning point. Because the detection for turning point is based on heading in GPS position which is not so accurate, it could make mistake to detect turning point sometimes.
