nRF52 dk issues with bonding PM_EVT_CONN_SEC_FAILED is called every time

[capricorn]

Hi

i am trying to connect ble_app_proximity with ios (10.0.2), but every time it is generating PM_EVT_CONN_SEC_FAILED for pm_evt_handler with sdk 12.2.0

i need to implement whitelist functionality once device is connected.

Thanks

@Hung Bui its working ok after erasing settings on both sides, but do we need to erase everytime we want to connect and bonding the devices.
