How to start working Device Information Work?

[JacOG]

Hi.

My target device is nRF51822 and SDK version is 12.3.0.

I try to add Device Information Service to example "ble_app_uart_pca10028_s130"

---------- main.c (added code below)

#include "ble_dis.h"

static ble_uuid_t                       m_adv_uuids[] = {
  {BLE_UUID_NUS_SERVICE, NUS_SERVICE_UUID_TYPE}
 , {BLE_UUID_DEVICE_INFORMATION_SERVICE, BLE_UUID_TYPE_BLE}
 };

static void services_init(void)
{

    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_srv_ascii_to_utf8(&dis_init.model_num_str    , (char *)MODEL_NUMBER);
    ble_srv_ascii_to_utf8(&dis_init.serial_num_str   , (char *)SERIALNUMBER);
    ble_srv_ascii_to_utf8(&dis_init.hw_rev_str       , (char *)HW_REV);
    ble_srv_ascii_to_utf8(&dis_init.fw_rev_str       , (char *)FW_REV);

    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);

}

-------- Project tree (added files)

/nRF_BLE_Service/ble_dis.c

After build and load, BLE advetiseing data shows Device Information Service exsting, but it does not works.

Nordic UART service (NUS) is works well.

Is there any other implemation or setting to activate DIS?

I know this isse https://devzone.nordicsemi.com/f/nordic-q-a/47105/working-principle-of-db-discovery-module
I already try to reset BLE On/Off of my iPhonem and nothig happen.

The code snipped looks quite OK. Could you attach a minimalistic project for me to test it out so that i can attempt to debug it. If ble_dis_init is executed without any error, then I would assume that this should work.

I attached Zip file of modifyed ble_app_uart project files.

The DIS service is showing up quite ok on the DK using phone or nrfConnect desktop. 

After build and load, BLE advetiseing data shows Device Information Service exsting, but it does not works.

This means the problem is your custom device specific, can you please run your application in debug mode and tell us more about what "does not works" means? does it get stuck in a loop or app_error handler?
