Refuse BLE connection if the phone is not in bonding list

[kevinlam]

Hello,

Is there a way to refuse BLE connection if the phone is not in existing bonding list in ESP32?

My idea is, to limit only 1 phone can bond and connect to ESP32 and don't want to use passkey in my application.

Thanks,
Kevin

I have tried to use whitelist to refuse the bonded device, but it seems has a bug and someone posted the related issue on github,

do you have any workaround right now?
