ETRX351 AND ETRX357
5.2 Software Interface
Using the default firmware the ETRX35x is controlled using a simple AT-style command interface
and (mostly) non-volatile S-Registers.
In order to get a full listing of all the available AT-
Commands, please refer to the AT command dictionary document which corresponds to the
firmware revision you intend to use.
In addition to the command dictionary there are user guides explaining the features of the firmware
in more detail. If you need to find out which firmware resides on your module simply type “ATI”
followed by a carriage return and you will be prompted with the module’s manufacturing
information.
The Development Kit manual describes how to upgrade the firmware either via a serial link or over
the air.
