Can a BLE slave know if Windows or Android has removed it from the whitelist?

[Liny]

I’d like to ask: I created a BLE keyboard based on nRF5 SDK + 52833 + S140, and it can pair and bond with Windows successfully. I have two questions:

1. If the keyboard is connected and Windows unbinds/removes the keyboard, can the keyboard know that the peer removed it from the whitelist? Or does it only know that the connection was lost?
2. If the keyboard is offline and Windows unbinds/removes the keyboard, can the keyboard detect that Windows has deleted it from the whitelist the next time it powers on?

Thanks!

Hello,

No, the keyboard has no way of knowing whether the computer has removed it from it's whitelist. There is an option to .allow_repair if a known host tries to bond again, which you can see in the ble_app_hrs example.
