This works perfectly:
Serial.println(“Aoreal_20!”); // Print firmware version
This crashe the IDE every time:
Serial.println(“Aoreal_20!!!”); // Print firmware version
I press the compile/upload button, the green progress line moves across all the way to the right (as if the compile/upload has happened OK), but then it stops (still showing) and no compiler/upload complete message appears, and if you park the mouse-pointer over the green progress bar, it shows as a little rotating “wheel”. After several minutes, the message “An error occurred while uploading the sketch” appears.
Prior to the message appearing, it is impossible to close or cancel or force the software to recover.
I am not sure whether this behaviour is as expected.
