Hi everyone, I made a development board with the RAK3172, which I’ve been working on. I recently tried to upload the P2P code to it, but they’re no longer communicating with each other. Do you know if it’s because the board is overloaded, or if something similar has happened to you?
Also, with the code to send data via LoRaWAN, it no longer sends data.
What P2P code did you use to upload on your RAK3172? Do you have two RAK3172? Is it custom board?
If it works before, what changes did you do that causes its stopped working? Did you change some parameters on code? did you change antenna? did you change power supply?
For LoRaWAN, what code did you use?
If it is not working on both P2P and LoRaWAN, the problem can be on the chip, its power supply, etc.
One thing you can also do is perform flash erase, upload latest FW then try AT commands first to check module’s functionality.
