Hey
I am proud owner of an ADAFRUIT FEATHER M0 BLUEFRUIT LE. Now I've followed the tutorial of adafruit completely. I have the plate and so on. As stated in the tutorial, I tried the show program as the first.
The problem begins:
Instead of "Done Uploading." ther is standing "An error occurred while uploading the sketch"
This is the message that says:
Sketch uses 9588 bytes (3%) of program storage space. Maximum is 262144 bytes.

An error occurred while uploading the sketch
Error while setting serial port parameters: 19,200 N 8 1
There may be an error message, but the bright program still works.
can harm the error or is this normal?
So I thought I just let go and see how far I come
Problem two:
I'm still pretty new in this programming world. My goal is to make a communication between smartphone and bluthooth module. The idea is to eventually turn on a led and turn off via smatphone and to register if, for example, a button is pushed that is linked to the bluethooth module.
Does anyone have an example of communication?
