How to wake up tablet PC via pushing a button on nrf52 board

[liu_zhixiang]

When nrf52 board and tablet PC connect, I set the tablet PC in sleep mode. Then how can I wake up tablet PC via pushing a button on nrf52 board. Maybe one event can realize this function. But I didn't find any illustration in official website.

It would have nothing specifically to do with the nRF52 - you would have to study the OS/developer documentation for the Tablet in question.

ie, does the Tablet OS support wakeup on BT events?
