I actually tried to upload a simple sketch that prints to serial:
// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
Serial.println("abc");
}
Again the sketch works only when uploaded from Arduino Create (returns "abc" on Serial) and although successfully uploaded from IDE doesn't return anything on Serial.
