often

**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;

**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

**Project release version**

Shipped with ESP-IDF 5.2.2

Start by reproducing the failure with ESP-IDF 5.2.2: perform a factory reset, call ble_store_clear(), and reconnect over BLE. Trace the bond and IRK removal path around the reported “Error while removing IRK” message and compare it with the disconnect logs. Done means BLE pairing works reliably after the reset without the IRK-removal error.
