Hi!

I can see that you have made a new thread with this issue.

https://devzone.nordicsemi.com/f/nordic-q-a/32640/add-manufacturer-data

Please try to keep the discussion in that thread.

Cheers.

hi Joakim Jakabsen

i am using sdk 14,nRF52 dk and trying add manufacturer data in sdk14 example.

as suggested by you in above reply i have added this to advertising .so advertising_ init()

{

ret_code_t err_code;
ble_advertising_init_t init;

ble_advdata_manuf_data_t adv_manuf_data;
uint8_t adv_manuf_data_data[] = "Data";
adv_manuf_data.data.p_data = adv_manuf_data_data;
adv_manuf_data.data.size = sizeof(adv_manuf_data_data);
adv_manuf_data.company_identifier = 0x0059; //Nordic's company ID

memset(&init, 0, sizeof(init));

init.advdata.name_type = BLE_ADVDATA_FULL_NAME;
init.advdata.include_appearance = true;
init.advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;

init.advdata.p_manuf_specific_data = &adv_manuf_data;
init.advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
init.advdata.uuids_complete.p_uuids = m_adv_uuids;

init.config.ble_adv_fast_enabled = true;
init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
init.config.ble_adv_fast_timeout = APP_ADV_TIMEOUT_IN_SECONDS;

init.evt_handler = on_adv_evt;

err_code = ble_advertising_init(&m_advertising, &init);

APP_ERROR_CHECK(err_code);

ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);

}

hardware is pca10040.i am getting return error code 12(invalid size) .please support

Murugan. I tried adding manufacturer data to the ble_app_blinky example in SDK 11, and it seems to be quite straight forward.

in advertising_init(void) i added:

ble_advdata_manuf_data_t 		  adv_manuf_data;
uint8_t 		                  adv_manuf_data_data[] = "Data";
	
adv_manuf_data.data.p_data        = adv_manuf_data_data;
adv_manuf_data.data.size          = sizeof(adv_manuf_data_data);
adv_manuf_data.company_identifier = 0x0059; //Nordic's company ID
advdata.p_manuf_specific_data     = &adv_manuf_data;

And it seems to be working just fine.
The 16-bit company ID (0x0059), is a unique 16-bit value assigned to Bluetooth SIG members. It is not allowed to broadcast a custom company ID value without being a member.

No problem, you are welcome to post another question if you run into any problems.

ok thank you. I will try then update you.

Yes, it should be possible to use the experimental_ble_app_blinky example as well.

Thanks for reply. I already implement and tested in ble_app_uart example. But now i want to use example experimental_ble_app_blinky. I want to know if it is possible ?

Take a look at the ble_app_beacon example

This includes manufacturer data, because iBeacons use manufacturer data to hold details of the beacon.

Note. You do not need to use exactly the same data structure for

static uint8_t m_beacon_info[APP_BEACON_INFO_LENGTH] =                    /**< Information advertised by the Beacon. */
{
    APP_DEVICE_TYPE,     // Manufacturer specific information. Specifies the device type in this
                         // implementation.
    APP_ADV_DATA_LENGTH, // Manufacturer specific information. Specifies the length of the
                         // manufacturer specific data in this implementation.
    APP_BEACON_UUID,     // 128 bit UUID value.
    APP_MAJOR_VALUE,     // Major arbitrary value that can be used to distinguish between Beacons.
    APP_MINOR_VALUE,     // Minor arbitrary value that can be used to distinguish between Beacons.
    APP_MEASURED_RSSI    // Manufacturer specific information. The Beacon's measured TX power in
                         // this implementation.
};

You can use a array of bytes instead.

You just need to setup the pointer to your data and also its length

manuf_specific_data.data.p_data = (uint8_t *) m_beacon_info;
manuf_specific_data.data.size   = APP_BEACON_INFO_LENGTH;

and

advdata.p_manuf_specific_data = &manuf_specific_data;

before calling

err_code = ble_advdata_set(&advdata, NULL);

One thing to be aware of, is that the size of the manufacturer data is limited by the maximum size of the advertising packet, and also what other data is in the advertising packet.

e.g. if you use a long name, and / or a 128 bit service etc in your advertising packet, there will be less spare for the manufacturer data
