Forget Device on IOS side handling

[Bloq]

Hello,

I am working with nRF52840 and started with SDK15 examples with BLE security mode 1 level 2, No MITM.  I have a question regarding bond handling and the deletion of bond data on the central side which for us is an IOS app.  When the user "Forgets Device" in settings of IOS, the peripheral cannot recognize this and during the next attempt to connect will try to use previous bond keys while the app tries to pair and re bond.  I am attempting to handle this in PM_EVT_CONN_SEC_FAILED with a pm_peer_id_get and then pm_peer_delete.  I want the devices to rebond in one connection so the user does not have to try again.  Is this the right way to handle this / safe place to delete a bond, etc?

        case PM_EVT_CONN_SEC_FAILED:
            m_conn_handle = BLE_CONN_HANDLE_INVALID;

            // Check if failure was because peer was already bonded
            if(pm_peer_id_get(p_evt->conn_handle, p_evt->peer_id) == NRF_SUCCESS)
            {
                NRF_LOG_INFO("PEER ALREADY BONDED...DELETING BOND FOR REBOND");
                err_code = pm_peer_delete(current_bonded_peer);
                APP_ERROR_CHECK(err_code);
            }
            break;

Thanks in advanced,

I have located the .allow_repairing sec config option but it is still not working.  I have implemented the following:

        case PM_EVT_CONN_SEC_PARAMS_REQ:
        {
            pm_conn_sec_config_t conn_sec_config = {.allow_repairing = true};
            pm_conn_sec_config_reply(p_evt->conn_handle, &conn_sec_config);
        } break;

but I still get a "Connection Alert: The peripheral disconnected while being interrogated. Dismiss" message on central IOS app.
Please help this seems to be the solution for everyone else.

Thanks,
