Hi, I am implementing the Linux-based device controlled by BLE (so, my device is peripheral and uses linux 6.6.20/bluez 5.73 stack onboard). To pair with it I set up an agent with NoIO capability (the device has no controls available for the user). When I enable pairable mode and try to send a pair request from the client (a mobile phone, nRF connect app), all works as expected. But if I remove pairing at the phone side and try to re-establish bonding, the bluez refuses it with 'auth failed' (0x5) status in the log. As I understand, it is expected behavior because the bluez has old bonding information and tries to use it instead of rewriting by new one.Is it possible to automatically override old bonding info in such a case and accept this pairing request? Looks like bluez service doesn't send any information via D-Bus in this situation.
