SDK 15.3 pairing issue

[skulkarni]

I am getting the below error message when I try to repair the device. 

peer_manager_handler: Connection security failed: role: Peripheral, conn_handle: 0x0, procedure: Bonding, error: 133

SDK Version: 15.3

Softdevice: S132 [nRF52832]

Example code : examples\ble_peripheral\ble_app_ancs_c

Hi

Again, you'll need to delete the bonds from your nRF. You should be able to do so by pressing button 2 while the nRF is asleep according to the BSP BLE Button Assignments, which is included in the ancs_c example according to the Infocenter.

Best regards,

Simon

Handling the PM_EVT_CONN_SEC_CONFIG_REQ in pm_evt_handler solved the issue.

case PM_EVT_CONN_SEC_CONFIG_REQ:
{
    // Reject pairing request from an already bonded peer.
    pm_conn_sec_config_t conn_sec_config; // = {.allow_repairing = true};
    conn_sec_config.allow_repairing = true;
    pm_conn_sec_config_reply(p_evt->conn_handle, &conn_sec_config);
} break;
