CDC Serial send blocks when host closes connection #6
Description
Hi,
I'd also like to point to the following issue, as it also applies to Arduino:
abcminiuser/lufa#106
I've already posted fixes for the LUFA core, something similar ca be implemented for Arduino. The main question for me is, if this behavior can be reproduced with other linux kernels or mac/windows. I currently have no other OS available, so someone else could maybe test the posted code.
Steps to reproduce:
- Upload the code
- Open Serial Monitor
- Close it
- Check if Led still blinks every 1s
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
//Serial.print("testegorogkrhtrhkhprtkpj\n"); <-- This works fine
for(uint8_t i = 0; i<100;i++){
Serial.write('a'); // <- This also crashes
}
}
