Expected behavior

I expected to see BLE pairing working fine after an esp32 factory reset

Actual behavior (suspected bug) :

After an esp32 factory reset, some devices fail to connect over BLE again (does not always happen). I get an error saying NimBLE: Error while removing IRK and I could not find a way to get it to work again.

Error logs or terminal output

I (5864) NimBLE: GATT procedure initiated: notify;
I (5874) NimBLE: att_handle=20
I (12714) NimBLE: GAP procedure initiated: terminate connection; conn_handle=0 hci_reason=19
E (12724) NimBLE: Error while removing IRK
I (12944) ble: disconnect, reason=534
W (12944) ble: client disconnected, connection id=0 [MAC ADDRESS]

I (12984) NimBLE: adv_channel_map=0 own_addr_type=0 adv_filter_policy=0 adv_itvl_min=0 adv_itvl_max=0
I (12994) NimBLE:

Steps to reproduce the behavior:

Perform a factory reset on esp32, Bonds are deleted using the ble_store_clear() function.
Attempt to connect over BLE again.
Get the above error

Hi,

I think similar issue with ble_gap_unpair() was fixed in NimBLE 1.7 [1]
I'm not sure which version of NimBLE is used in ESP-IDF 5.2.2 but maybe it is related
