why do you set the edge trigger like that? [image] you can also see this document on how to set wakeup source (at least can make sure the GPIO pin is working fine): [image] Wake up from suspend mode on GPIO interrupt You can see this document: How to use GPIO as wakeup source on …

ok, it does work by using the <2>, low level trigger. Still doesn`t work with the pmtool of legato…

i never use pmtool you can send AT command for your application
