nrf51822 Device manager not showing bonded devices

[hardikvala]

Hi

I am using device manager and store connected devices value on next advertise device should be broadcast as bonded 

static uint32_t device_manager_evt_handler(dm_handle_t const * p_handle,
                                           dm_event_t const  * p_event,
                                           ret_code_t        event_result)
{
    //DBGF("DM evt %u\r\n", p_event->event_id);
    APP_ERROR_CHECK(event_result);
    return NRF_SUCCESS;
}



void device_manager_init(bool erase_bonds)
{
    uint32_t               err_code;
    dm_init_param_t        init_param = {.clear_persistent_data = erase_bonds};
    dm_application_param_t register_param;

    // Initialize persistent storage module.
    err_code = pstorage_init();
    APP_ERROR_CHECK(err_code);

    err_code = dm_init(&init_param);
    APP_ERROR_CHECK(err_code);

    memset(&register_param.sec_param, 0, sizeof(ble_gap_sec_params_t));
    
    register_param.sec_param.bond         = BLE_TAG_SEC_PARAM_BOND;
    register_param.sec_param.mitm         = BLE_TAG_SEC_PARAM_MITM;
    register_param.sec_param.io_caps      = BLE_TAG_SEC_PARAM_IO_CAPABILITIES;
    register_param.sec_param.oob          = BLE_TAG_SEC_PARAM_OOB;
    register_param.sec_param.min_key_size = BLE_TAG_SEC_PARAM_MIN_KEY_SIZE;
    register_param.sec_param.max_key_size = BLE_TAG_SEC_PARAM_MAX_KEY_SIZE;
    register_param.evt_handler            = device_manager_evt_handler;
    register_param.service_type           = DM_PROTOCOL_CNTXT_GATT_SRVR_ID;

    err_code = dm_register(&m_app_handle, &register_param);
    APP_ERROR_CHECK(err_code);
    
}

this is my device manager and evt handler

static void sys_evt_dispatch(uint32_t sys_evt)
{
    pstorage_sys_event_handler(sys_evt);
    ble_advertising_on_sys_evt(sys_evt);
}

static void ble_evt_dispatch(ble_evt_t * p_ble_evt)
{
    //DBGF("ble_evt_dispatch %X\r\n", p_ble_evt->header.evt_id);
    on_ble_evt(p_ble_evt);
    ble_conn_params_on_ble_evt(p_ble_evt);
    ble_advertising_on_ble_evt(p_ble_evt);
    ble_tag_on_ble_evt(&m_tag, p_ble_evt);

    dm_ble_evt_handler(p_ble_evt);
}

still my connected device doesn't show as bonded.

Kindly help me out on this what is that I am missing here

Hi,

I'm not sure what you mean by "still my connected device doesn't show as bonded.", where do you want the app to show up as bonded, in the FW or in the Mobile app?

On mobile app says bonding fail and than device reset

It may be caused by an assert in your code (error code passed to APP_ERROR_CHECK). Have you tried to debug the application to see if the program ends up in the app error handler?
