I'm not super great with electronics and dont understand why raspberry pi can send serial commands to DHB-10 contorl board but not receive any. I understand it has something todo with the wiring on DHB side?
So I believe DHB uses 5V for serial communication, whilst raspbeery uses 3.3v. But I tried using a pull down from DHB and it didnt work. I can successfully send commands to DHB, but not receive any (receiving on arduino works)
Does someone know how to solve this?
