Hello,

Not sure why this case have been thrown around in the system, but it made it to me now so I will try to take a look. You should expect an answer faster than this.

I am not going to directly answer your question, because I think there exists kconfig options that will for most part solve what you want to do. Please check out:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/kconfig/index.html#CONFIG_BT_ID_UNPAIR_MATCHING_BONDS
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/kconfig/index.html#CONFIG_BT_ID_ALLOW_UNAUTH_OVERWRITE
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/kconfig/index.html#CONFIG_BT_KEYS_OVERWRITE_OLDEST
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/kconfig/index.html#CONFIG_BT_SMP_ALLOW_UNAUTH_OVERWRITE

If you want full control over this, you may also look into using the bt_id_get() and bt_id_create() api after bt_enable(), but between connections:
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/connectivity/bluetooth/api/gap.html#c.bt_id_create

Example usage of that api:

https://github.com/nrfconnect/sdk-zephyr/blob/v2.6.99-ncs1-snapshot1/samples/bluetooth/peripheral_identity/src/peripheral_identity.c#L44

Sorry for the late answer, but hope that is relevant,
Kenneth

I keep getting "An engineer has been assigned to..." messages related to this ticket, but no actual replies here. Has anyone able to do this successfully and can point me in the direction of a solution?

Best regards,

Mike

Seems to be lots of tickets about this on DevZone, but all of them appear to be related to the old SDK, and not to NCS.

I have been trying to use bt_id_get() API to at least see if I can see that bonding/pairing info is being stored, but that's not giving me the sort of information I would expect to see.

Not sure if that API is even the right one to be using

Cheers,
Mike
