  • Page 9: Overview

    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.

  • Page 10: System Architecture

    GL300 @Tracker Air Interface Protocol 2. System Architecture 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.

  • Page 11: Message Description

    GL300 @Tracker Air Interface Protocol 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 ‘$’.
  • Page 12 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.

  • Page 13: Command And Acknowledgement

    GL300 @Tracker Air Interface Protocol 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.
  • Page 14 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 SMS.
