HI all,

If yes, can you please post firmware version (Sierra/AT/Generic… ) and other details?  
We are tryng all mixes but it seems not to work at all.

Hi Gi1,

I checked this feature on WP7702 device and it works. My device uses the firmware Generic Revision: SWI9X06Y\_02.36.08.02.

The device can be waked up by GIPO36 by below commands  
at!powerwake=2,36,2  
at!powermode=3

Could you please follow and give it a try?  
Thanks,
