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?

I just know last project maybe use HID to wake up tablet, like in BLE_HIDS_EVT_BOOT_MODE_ENTERED event to set m_in_boot_mode = true. Then some API can be called(maybe in BLE_HIDS_EVT_NOTIF_ENABLED event) when PC is in sleep mode to wake up it.

Do you have any ideas? Thanks awneil.

Those are all events within the Nordic SDK

So not relevant to the PC.

Again, it's the PC documentation that you need to be studying ...

eg, https://developer.android.com/
