pairing failed

[anna]

Hi ,Nordics

when I use my host device (reffered to the example of ble_app_hrs_c)to pair and bond with a peripheral device(a gamepad) ,the pairing failed .I don't kown the reason .And when I try to enable the cccd ,it failed . I want to know why this happened ?In my project ,I just want to receive the datas through the host . The peripheral device pairing and bonding with mobile phone process is as below .

DM configuer is :

static 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;

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));

// Event handler to be registered with the module.
register_param.evt_handler            = device_manager_event_handler;

// Service or protocol context for device manager to load, store and apply on behalf of application.
// Here set to client as application is a GATT client.
register_param.service_type           = DM_PROTOCOL_CNTXT_GATT_CLI_ID;

// Secuirty parameters to be used for security procedures.
register_param.sec_param.bond         = SEC_PARAM_BOND;
register_param.sec_param.mitm         = SEC_PARAM_MITM;
register_param.sec_param.io_caps      = SEC_PARAM_IO_CAPABILITIES;
register_param.sec_param.oob          = SEC_PARAM_OOB;
register_param.sec_param.min_key_size = SEC_PARAM_MIN_KEY_SIZE;
register_param.sec_param.max_key_size = SEC_PARAM_MAX_KEY_SIZE;
register_param.sec_param.kdist_periph.enc = 1;
register_param.sec_param.kdist_periph.id  = 1;

// register_param.sec_param.kdist_periph.sign =1; err_code = dm_register(&m_dm_app_id, &register_param); APP_ERROR_CHECK(err_code); }

And if you use the same Security parameters with your own project?
