Thanks a lot Morten, i got the point. Since, i was calling the services_init(); after advertising_init(); i couldn't able to get the value for m_accel.uuid_type, and the error value i got is 0x00000007. Thank you.

... which is exactly why you should have it there, catch the error and make sure you understand it, fix the cause of it, and then see everything working as it's supposed to.

Also, as I've told you before, you should remove the reset from app_error_handler, and use the debug_assert_handler, so that you can easily catch such errors.

I tried with APP_ERROR_CHECK(err_code); now my device is not advertising.

You don't check the error code returned by ble_advdata_set(). You should ALWAYS check error codes!

I tried as you said, but in MCP, i couldn't see any values below the Advertising Data, and Scan Response Data. I attached the image of my MCP, and also edited the above post with my code.

There shouldn't be any particular problems with this, and it can be done for example as follows (modified from the nAN-36 code):


    ble_uuid_t adv_uuids[] = {{LBS_UUID_SERVICE, m_lbs.uuid_type},
                              {BLE_UUID_HEART_RATE_SERVICE, BLE_UUID_TYPE_BLE}};

    // Build and set advertising data
    memset(&advdata, 0, sizeof(advdata));
    advdata.name_type               = BLE_ADVDATA_FULL_NAME;
    advdata.include_appearance      = true;
    advdata.flags.size              = sizeof(flags);
    advdata.flags.p_data            = &flags;
    
    memset(&scanrsp, 0, sizeof(scanrsp));
    scanrsp.uuids_complete.uuid_cnt = sizeof(adv_uuids) / sizeof(adv_uuids[0]);
    scanrsp.uuids_complete.p_uuids  = adv_uuids;
    
    err_code = ble_advdata_set(&advdata, &scanrsp);
    APP_ERROR_CHECK(err_code);

Edit: Your added code snippet does not check the error code of ble_advdata_set(), and based on your screenshots, it's pretty likely that advdata_set() returned an error and didn't do anything. You should always check error codes!
