nRF52832 ble_app_uart dis_init

[sfujimoto]

Please tell me about rudimentary things. Can I add dis_init to ble_app_uart with nRF 52832-SDK, for example?

Hi,

Yes, that is possible. Below are the steps required to add DIS to the ble_app_uart project in SDK 12

1. Add ble_dis.c to your project. It's located in the folder:

   SDK_INSTALL_FOLDER/components/ble/ble_services/ble_dis
   

2. Include the ble_dis header file in main.c:

   #include "ble_dis.h"
   

3. Add the DIS to the m_adv_uuids array:

   static ble_uuid_t                       m_adv_uuids[] = {{BLE_UUID_NUS_SERVICE, NUS_SERVICE_UUID_TYPE},
                                                            {BLE_UUID_DEVICE_INFORMATION_SERVICE, BLE_UUID_TYPE_BLE}};  /**< Universally unique service identifier. */
   

4. Add the manufacture name to be used by the DIS:

   #define MANUFACTURER_NAME   "NordicSemiconductor"  /**< Manufacturer. Will be passed to Device Information Service. */
   

5. Enable BLE_DIS_ENABLED in sdk_config.h:

   #ifndef BLE_DIS_ENABLED
   #define BLE_DIS_ENABLED 1
   #endif
   

6. Add the DIS initialization to the services_init() function:

   static void services_init(void)
   {
   uint32_t       err_code;
   ble_nus_init_t nus_init;
   
   memset(&nus_init, 0, sizeof(nus_init));
   
   nus_init.data_handler = nus_data_handler;
   
   err_code = ble_nus_init(&m_nus, &nus_init);
   APP_ERROR_CHECK(err_code);
   
   // Initialize Device Information Service.
   ble_dis_init_t dis_init;
   memset(&dis_init, 0, sizeof(dis_init));
   
   ble_srv_ascii_to_utf8(&dis_init.manufact_name_str, (char *)MANUFACTURER_NAME);
   
   BLE_GAP_CONN_SEC_MODE_SET_OPEN(&dis_init.dis_attr_md.read_perm);
   BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS(&dis_init.dis_attr_md.write_perm);
   
   err_code = ble_dis_init(&dis_init);
   APP_ERROR_CHECK(err_code);
   }
