nRF5340 have to reset device to try consecutive pairing attempt on cancel or timeout of attempt from iOS

[responsible_duck]

Hello,

On a pairing failure from iOS (either cancel or timeout of the pairing dialog alert "Bluetooth Pairing Request"), the device no longer allows pairing until a software reset is issued. It does seem to clear keys properly when it fails though...There must be some weird cache thing happening but I don't see anything obvious in the SDK code.

Did the device disconnect and the disconnect event handled here?

Did you try using bt_unpair() to manually reset the statemachine to normal if there are any wrong memory states in settings?

Yes unfortunately running 

bt_unpair(BT_ID_DEFAULT, BT_ADDR_LE_ANY);

 

has no effect on the device's ability to repair without a reset.
