R309 AT Commands

1 Introduction

1.1 The first step

Send the command “ATI” to a module to find its firmware version. If it is not R309 then you should

refer to the correct version of the AT command manual, or send an e-mail to

zigbeesupport@telegesis.com requesting a copy of the R309 firmware file. All four variants of the

ETRX357 module share the same file.

Alternatively if your module has R309 and you prefer a different version, this can be provided on

request.

All the standard AT command set firmware files are free of charge to users who already have the

ETRXn devices, but they must only be used on Telegesis modules.

1.2 Module overview

This document describes the AT-Command interface firmware of the ETRX3 series ZigBee PRO

wireless meshing modules. It applies to the R309 firmware, which can be loaded on to all products

of the ETRX3 module series, for example:

- ETRX357, ETRX357-LR, ETRX357-LRS

- ETRX357HR, ETRX357HR-LR, ETRX357HR-LRS

- ETRX3585, ETRX3587 and ETRX3588

- ETRX3USB

- ZigBee Communications Gateway

The Telegesis ZigBee modules have been designed to be built into any device and provide a low

cost, low power ZigBee solution based on the industry leading EmberZNet ZigBee stack.

Integration into a wide range of applications is made easy using a simple AT-style software

interface and advanced hardware design.

No RF experience or expertise is required to add this powerful wireless networking capability to

your products. Telegesis ZigBee modules offer fast integration opportunities and the shortest

possible time to market for your product.

Important note

Using the AT-Command interface described in this document can shorten the time to market

significantly, however customers using the range of Telegesis modules also have the option of

using Ember’s EZSP interface firmware or of developing custom firmware using the Ember

Development tools.
