Hi, I am running ANCS example application (nRF5_SDK_15.3.0_59ac345/examples/ble_peripheral/ble_app_ancs_c) i changed allow_repairing = false to allow_repairing = true
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};
pm_conn_sec_config_reply(p_evt->conn_handle, &conn_sec_config);
}
break;
for repairing if the device forget from ios . again i connected to same device its connecting and pairing and i am getting notifications. when ever i disconnected previously connected device, and i am trying to connect with another device i am unable to connect and unable to pair the device.
and I am attaching the following files
