light sleep and uart

  • Good morning,

    is there a way in order to user light sleep and uart (pin P3 and P4)?

    machine.pin_sleep_wakeup(['P4'], machine.WAKEUP_ANY_HIGH, False)

    i want send AT command to an external module via Uart (pin P3--> Tx and Pin P4 -->Rx) and go in Light sleep mode (machine.sleep()), when i wait for the answer.
    I would like to wake up when i receive something on pin P4 (machine.pin_sleep_wakeup(['P4'], machine.WAKEUP_ANY_HIGH, False) )

    is it possible?



  • @Alessandro-Cortese There is no way implemented to stop machine.sleep().
