RE: added service nRF51 SDK9

Thanks for answer. There are two projects in examples (SDK9): 1- ble_app_uart_s130 I call

services_init();

where I call

err_code = ble_nus_init(&m_nus, &nus_init);

where I added UUID

ble_uuid128_t nus_base_uuid = NUS_BASE_UUID;
...
err_code = sd_ble_uuid_vs_add(&nus_base_uuid, &p_nus->uuid_type);

And at this case I can observer on my smartfone (central role) this UUID when discovered.

2- In those examples we have ble_app_template where I insert same code like previwes example into

static void services_init(void)
{
    /* YOUR_JOB: Add code to initialize the services used by the application.
    uint32_t                           err_code;
    ble_xxs_init_t                     xxs_init;
    ble_yys_init_t                     yys_init;

    // Initialize XXX Service.
    memset(&xxs_init, 0, sizeof(xxs_init));

    xxs_init.evt_handler                = NULL;
    xxs_init.is_xxx_notify_supported    = true;
    xxs_init.ble_xx_initial_value.level = 100; 
    
    err_code = ble_bas_init(&m_xxs, &xxs_init);
    APP_ERROR_CHECK(err_code);

    // Initialize YYY Service.
    memset(&yys_init, 0, sizeof(yys_init));
    yys_init.evt_handler                  = on_yys_evt;
    yys_init.ble_yy_initial_value.counter = 0;

    err_code = ble_yy_service_init(&yys_init, &yy_init);
    APP_ERROR_CHECK(err_code);
    */
			
	ble_uuid128_t base_uuid = NUS_BASE_UUID;   
	ble_uuid_t    ble_uuid = { . uuid = BLE_UUID }; 
    uint32_t 	  err_code = sd_ble_uuid_vs_add(&base_uuid, &ble_uuid.type);
    APP_ERROR_CHECK(err_code);
  
	uint16_t      service_handle;		  
    err_code = sd_ble_gatts_service_add(BLE_GATTS_SRVC_TYPE_PRIMARY, &ble_uuid, &service_handle);  
    APP_ERROR_CHECK(err_code);	
	
	sd_ble_gap_appearance_set(BLE_APPEARANCE_GENERIC_TAG);
}

but now I can't see on my smartfone same service. Why?

Use "nrf Connect" to connect with your device ，then check if there is an unknown service has the same uuid with yours.

It seems that you are adding a vendor defined uuid .You should describe your question more detailed. You don't see this service ,by scanning or connecting ? If scan ,you should add uuid to advertising packet, if connected, you should check your initialization procedure.

Hi: I don't think it's right. ----> #define BLE_UUID 0x0005 Look at this defination : uint16_t uuid; /**< 16-bit UUID value or octets 12-13 of 128-bit UUID. */

If your UUID is true service uuid,the right value should be 0x0000 , 12-13 of 128-bit UUID. But you can see that ,its name is NUS_BASE_UUID. You know? It's a basal uuid.

12-13 of nus service is defined by nordic ,you can not change it . As I know , ble uart service's (nus) UUID is 0x0001

#define BLE_UUID_NUS_SERVICE 0x0001
#define BLE_UUID_NUS_TX_CHARACTERISTIC 0x0002/**< The UUID of the TX Characteristic. */
#define BLE_UUID_NUS_RX_CHARACTERISTIC 0x0003 /**< The UUID of the RX Characteristic.*/
