Hi, this is my first post and first time working on an stm, so I am a bit new to this. I have a circuit I have been working on as a hobby. When the circuit is receiving, it is getting data from a device, and when it is transmitting, it is charging the device. Something is wrong, and the frustrating part is that it compiles correctly. I am looking for advice on things to look into or to think about. I feel that general discussion on this will help me. Thanks a ton.
