ETRX351 and ETRX357 5 Firmware Description The modules will be pre-loaded with a standalone bootloader which supports over-the-air bootloading as well as serial bootloading of new firmware. In order to enter the standalone bootloader using a hardware trigger pull PA5 to ground and power-cycle or reset the module. To avoid entering the standalone bootloader unintentionally make sure not to pull this pin down during boot-up unless the resistance to ground is >10kΩ. (A pull-up is not required).
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 ATCommands, 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.

ETRX351 and ETRX357 14 Recommended Footprint In order to surface mount an ETRX3 series module, we recommend that you use pads which are 1mm wide and 1.2mm high. You must retain the keep-out zone shown in section 12, and ensure that this keep-out area is free of components, copper tracks and/or copper planes/layers. You must also ensure that there is no exposed copper on your layout which may contact with the backside of the ETRX3 series module.
ETRX351 and ETRX357 14.1 Example carrier board Since the RF performance of the module with the on board antenna is strongly dependent on the proper location of the module on its carrier board, Figure 10 shows the reference carrier board which was used during testing by Telegesis. Figure 10. Reference Board For best performance it is recommended to locate the antenna towards the corner of the carrier board and to respect the recommended keep-out areas as described in section 11.
