UART() doesn't recieve data after wakeup from sd_app_evt_wait()

[shah_shah]

I am using uart to transfer data in a while loop, and it works fine. Now I want CPU to go to sleep mode with sd_app_evt_wait(), and CPU to be waken up via Button then receive uart data via GPIOTE and GPIO. The CPU is woken up on button press and the handler is called. But from there I can't receive data via uart? Does anybody have idea what went wrong? I am using nrf51422 and SDK12.3

Is this handler executes in interrupts context? If yes, is interrupt nesting supported or just they are disabled while executing in interrupts context? It can be due to disabled interrupts in Interrupts context? Because I am using uart interrupts for reception.
