Hi Piyush, 

Which SDK are you using ? 
If you use NCS  SDK you can try testing with the \zephyr\samples\bluetooth\ibeacon example. 
You can add the scan response data, similar to the advertising data: 

err = bt_le_adv_start(BT_LE_ADV_NCONN, ad, ARRAY_SIZE(ad),

                  ad2, ARRAY_SIZE(ad2));

Note that you need to use Apple Company ID in your manufacturer data (0x4c)

I am using nrfsdk 17.1.0

Have you tried to modify ble_app_beacon so that it advertise as iBeacon (with the advertising packet) ?

Hi, 
If it's the case, you can do the following change to add the scan response packet in: 
- Change  m_adv_params.properties.type  in advertising_init() from BLE_GAP_ADV_TYPE_NONCONNECTABLE_NONSCANNABLE_UNDIRECTED to BLE_GAP_ADV_TYPE_NONCONNECTABLE_SCANNABLE_UNDIRECTED  so that it allows scan request/response. 

- Edit the m_adv_data struct to add a similar array as m_enc_advdata into scan_rsp_data for example create a m_enc_advdata2. Again, note that you need to use company ID 0x4c in the manufacturer data so that Apple recognize it as iBeacon.
