RAK4631 is supported through web flasher, but PIO project doesn't seem to have target for RAK4631. How to build?

Hi, 4631 is flashed with UF2 types of files. The code is "almost" the same as the ones for ESP32 just worked on a secondary-private repository.

I'm planning on adding it as a big repository for iGate but so far haven't had the time.

Any special request to see about on the code to share?

Thank you for the response. I was thinking about looking into why it was doing CAD even though I set it to off in the configurator (https://github.com/richonguzman/LoRa_APRS_iGate/issues/474).

I was also trying to look into how to get TNC serial on the RAK4631, when I can't enable serial in a web GUI, and the configurator doesn't seem to have an option for it.

the Configurator is just a basic second way to send configuration data over serial for the Digi RAK4631

will check about any missing variable handling the CAD process

I closed the other issue since it was resolved by a flash erase. I still wanted to check the code to see what is needed to use the RAK4631 as a TNC. I can flash it and configure, but then nothing really happens. I've tried using it via serial in Pinpoint APRS but it doesn't transmit or receive anything. Are there any instructions on how to get RAK4631 up and running?

by TNC is ment as BLE TNC for using with Phone Apps. Your aim is to use it as USB TNC to receive lora packets and see it on the PinPoint PC App ?

Ah, I thought it was for serial. I'll try bluetooth. Thank you!
