TWR Plus Project

[sysadminpower2019]

Hello,

I read on the lilygo site that you were building an APRS tracker project with the TWR plus but I can't seem to find any info on github and couldn't find a better place to ask about it.

thanks

I have this almost ready:

Works as a handy , has gps , screen and sends tones

But I can't find q way to send afsk and decode it

there are a few projects that use this same or similar hardware layout maybe you can get some inspiration from them

https://github.com/Hamlabs/ArcticTracker-ESP32
https://github.com/VanceVagell/kv4p-ht
https://github.com/OpenRTX/OpenRTX/tree/master/platform/targets/ttwrplus

plus here is the firmware that I had to install on my openedition twr to get it to work

Note that my T-TWR spontaneously went into short circuit, heated up and started smoking while sitting on my shelf in off state and untouched for more than a week. Lilygo claim it is impossible, but I am sure if by lucky coincidence wasn't in the room at the time it would have caused a fire in my house.
