    Hello,

    I have seen the post : https://www.udoo.org/forum/threads/wake-and-sleep-via-arduino-101.9237/

    I am using linux, do I just need to do this in the arduino sketch to wake up or sleep the udoo ? :

    for(int i=0; i<5; i++) {
    digitalWrite(reset_pin, LOW);
    delay(pulse_time); /* Reset pin goes LOW for 8ms */
    digitalWrite(reset_pin, HIGH);
    delay(pulse_time); /* Reset pin goes HIGH for 8ms */
    }

    and set the reset_pin to 9 ?

    Is there a way to know in the arduino sketch if the udoo is asleep or awake before using this command ?

    thanks

    Thanks for the answer, that's very useful.
    If a programm is running (like a web page) on the Udoo and the arduino forces to sleep then wake it up. Will the Udoo be still running the programm ?

    I do not know. Perhaps there is some Braswell pin that changes. You could also check if the serial device between Arduino and Braswell is up. But then you have to check the serial device on the Braswell side too.
