Happy New Year everyone!
By popular demand, the GTM Lab project is now live on GitHub - sybip/gtm-lab: goTenna Mesh protocol playground
From the project introduction:
This is a fun project to study and re-implement the goTenna Mesh protocols on inexpensive hardware based on the ESP32 MCU and RFM95W radio modules, using only unrestricted, publicly available information. All project code is open source under the MIT license.
Currently it’s nowhere near a complete relay, or even endpoint solution, and will probably never be a true drop-in replacement for goTenna brand devices, however:
(it) can send and receive messages to/from the goTenna mesh network
And this alone should be sufficient for a few hours of fun and excitement - a well-deserved break from these stressful times.
