Send Integer From Android to Arduino Serially #13

Closed gepetto82 closed 1 year ago

gepetto82 commented 1 year ago

How can I use the

serial_port.write(b'Hello world!')

Command given at the end of the example.py document to send an integer from android device to arduino?

Serial communication sends all kinds of data in sequence of bytes. The sending and receiving devices must agree on how these bytes are packed and unpacked. In your code, you can do this by using struct.pack and struct.unpack.

Since this is not a real issue, I will close it in 24 hours.
