Telegesis modules are low-power 2.4 GHz ISM band transceivers based on EM35x single chip Zigbee / IEEE 802.15.4 solutions. The unique AT-style command line interface allows developers to quickly integrate meshing radio technology.

On this page you will find the firmware for these transceivers. While the R309 firmware is the latest firmware, you can find versions as far back as the R303 firmware. We also have a change log attached outlining version by version changes.

Information on the Telegesis modules and kits can be found at this link.

Documentation on the Telegesis modules and kits can be found here.

PTI (Packet Trace Interface) Capture is a light-weight command line utility that captures network traffic information via the Packet Trace Interface on Silicon Labs EFR32 and EM3xx devices.

This utility provides the equivalent network capture functionality of Simplicity Studio's Network Analyzer tool without opening the GUI, therefore making it useful for a large capture over a long time with minimal involvement of your computer's resources.

The latest release of the silabs-pti-capture.jar software can be found at:

https://github.com/SiliconLabs/IoT_Utility_Scripts/tree/master/pti_capture

For assistance, please refer to the user guide (README.md).

For more information on the Packet Trace Interface and why you should use it, please refer to this related KBA on Why should I enable the PTI peripheral.
