How to keep wifi AP turn on when Jetson goes to sleep

Autonomous Machines Jetson & Embedded Systems Jetson TX2

Hi,
I was working on Jetson TX2 NX and using rtl8822ce chip for wifi and connecting through PCIe.
ubuntu 18.04
kernel 4.9.253-tegra
Now the wifi module is turned off when the jetson goes to sleep. I need to make the device always connected to the wifi AP of the board during sleep/suspend conditions.

Is there any way to keep wifi working in the sleep/suspend mode?
Is Jetson TX2 NX supportable to WoWlan?

We don’t have any usecase for WoWlan before.

Also, this requires the wifi chip capability to support too. So you can firstly check if this rtl8822ce supports this or not.

rtl8822ce is supporting to WoWlan.

We don’t have such function supported. Need to consult with more teams. Will update later.
