nRF52832 ble_app_uart dis_init

Question

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 
 
 
 Add ble_dis.c to your project. It's located in the folder: 
 SDK_INSTALL_FOLDER/components/ble/ble_services/ble_dis
 
 
 
 Include the ble_dis header file in main.c: 
 #include "ble_dis.h"
 
 
 
 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. */
 
 
 
 Add the manufacture name to be used by the DIS: 
 #define MANUFACTURER_NAME "NordicSemiconductor" /**< Manufacturer. Will be passed to Device Information Service. */
 
 
 
 Enable BLE_DIS_ENABLED in sdk_config.h : 
 #ifndef BLE_DIS_ENABLED
#define BLE_DIS_ENABLED 1
#endif
 
 
 
 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);
}
