Recently I observed an issue on RTL8722DM deep sleep. The RTL8722DM deep sleep and wakeup works fine for around 3-5 days but unbales to wakeup after that. I am using “AON\_TIMER”.  
#define AON\_TIMER\_SLEEP\_DURATION 50_60_1000//10000 // deepsleep time duration 50 to 32760000ms  
#define AON\_TIMER\_WAKEUP\_DURATION 10_60_1000 \*1000 // wakeup time duration 10 minute

It works fine for around, 3-5 days, I have also checked it with three RTL8722DM Board, but same issue.  
Is this a firmware issue or anything else, Please help.  
Thanks

Noted, so issue were found while using Arduino SDK 3.1.2?
