Nrf51822中设置128bit UUID service

 

uint32_tble_dajia_add_service(ble_dajia_t *p_wechat)

{

                   uint32_t err_code;

                   ble_uuid_t ble_wechat_uuid;

                   const ble_uuid128_tbase_uuid128 =

    {

        {

            0x23, 0xD1, 0xBC, 0xEA, 0x5F, 0x78,0x23, 0x15,

            0xDE, 0xEF, 0x12, 0x12, 0x00, 0x00,0x00, 0x00

        }

    };

                   ble_wechat_uuid.uuid =0x1122;

                  

                   //BLE_UUID_BLE_ASSIGN(ble_wechat_uuid,BLE_UUID_DAJIA_SERVICE);// ??UUID

                   err_code =sd_ble_uuid_vs_add(&base_uuid128, &(ble_wechat_uuid.type));

                   if (err_code != NRF_SUCCESS)

    {

        return err_code;

    }

                  

                   err_code =sd_ble_gatts_service_add(BLE_GATTS_SRVC_TYPE_PRIMARY, &ble_wechat_uuid,&p_wechat->service_handle);

                   return err_code;

}

 

安卓端搜索到的UUID字符串是：03-17 16:24:45.595:E/DeviceScanActivity(31942): -->serviceuuid:00001122-1212-efde-1523-785feabcd123

 

在Nordic开发板中是小端格式，uuid字符串和开发板中设置的字节序是相反的。
