HC05 connection
Hello, I'm trying to connect an HC-05 bluetooth module to my Nucleo F401-RE board but it is not working properly: When connected to D2/D8 and the board is connected to PC USB I can "sometimes" get an output on TeraTerm COM4, but if it usues a stand-alone power supply it does not work. I have read of conficts with debug RX/TX. Can anybody suggest me which pins should I use and provide a sample code? Thank you!
