Do my Indexes match my Code? (Bluetooth classic)

Try to narrow the error down: run another program on the board. If the problem persists, it's not the program that's causing the issue.

22

It's from my program now, but where can it come from?
I've been looking for 2 days but I can't find it...

23

avrdude: ser_open(): can't set com-state for ".\COM4"

this is a problem with the connection, not with the Sketch code.
Plug into another USB port, correctly set the port in the Arduino IDE, correctly load the Arduino driver...

This code is not finished, but you can study it...

Hi, when I put the code, same error as before, I don't know where it can come from, if you could still help me really sorry

this is a problem with the connection

Try with driver ch341
