[Question] how to turn off the RF supply only?

[Tong Meng]

Hello everyone,

I am trying to turn off the WiFi interface for energy saving purpose when the phone acts as WiFi-Direct GO.
I have tried to adopt IMPS, but found that after the WiFi interface wakes up from IMPS, its time stamp will be lost and increases from zero, which can break the link.
So I wonder if there is some method to only turn off the RF supply without influencing the other part?


Thanks for your time.


Sincerely yours,
David
