light sleep and uart

[Alessandro Cortese]

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?

regards,

Alessandro

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