We did see problems with Android and the device manager (predecessor to peer manager) when there was a shift in what address types Android uses. I recommend peer manager over device manager for that reason.

AFAIK the default in recent versions of Android is random addresses, either resolvable private address or non-resolvable private address.

It depends on the type of address, but if it is a bonded device then you can identify and authenticate the device. See peer manager as suggested by @jorg1

Yes, look into the module peer_manager in the nRF5 SDK (or device_manager on older versions of the SDK)Link to peer_manager docs

Hi,

The address of a BLE device can change, depending on what type of address it uses. See this answer for the various address types and how they are supposed to behave.
