How to advertise a special data?

[Ted]

Hi friend,

I use SDK16.0, and the version of softdevice is S140 V7.0.1.  Can I advertise a special data? like 0x08,0xff,0xa6,0x02,0x33,0x09,0x55,0x00,0x0c. 0x08 is packet length and 0xff to 0x0c are data.

Thank you in advance.

Hello,

Are you trying to include the "MANUFACTURER SPECIFIC DATA" in your advertisment payload? In that case, you may use the ble_app_beacon example as a reference. It includes this field in the advertisment package.

Best regards,

Vidar

Hi Vidar,

Yes, I tried. But I am getting error code in sd_ble_gap_adv_start function. The error code is 5 (NRF_ERROR_NOT_FOUND). My code snippet is below. I don't know know to fix it.

Best wishes

static uint8_t manufacturing_data_payload_list [] =
{
    0x33,
    0x09,
    0x55,
    0x00,
    0x0c
};

void manuf_data_start(void)
{
	ret_code_t err_code;
    ble_advdata_manuf_data_t manuf_specific_data;
    ble_advertising_init_t init;

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

    init.advdata.name_type               = BLE_ADVDATA_NO_NAME;
    init.advdata.include_appearance      = false;
    init.advdata.flags                   = 0;
    init.advdata.uuids_complete.uuid_cnt = 0;
    init.advdata.uuids_complete.p_uuids  = NULL;

    manuf_specific_data.company_identifier = 0x02A6;
    manuf_specific_data.data.size = 5;
    manuf_specific_data.data.p_data = manufacturing_data_payload_list;

    init.advdata.p_manuf_specific_data = &manuf_specific_data;

    init.config.ble_adv_fast_enabled  = true;
    init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
    init.config.ble_adv_fast_timeout  = APP_ADV_DURATION;
    init.config.ble_adv_on_disconnect_disabled = true; //if device disconnect, not needs auto adv again.
	
    init.evt_handler = on_adv_evt;

    err_code = ble_advertising_init(&m_advertising, &init);
    APP_ERROR_CHECK(err_code);

    err_code = ble_advertising_start(&m_advertising, BLE_ADV_MODE_FAST);
    APP_ERROR_CHECK(err_code);
}

Hi Ted,

To start connectable advertising, you need to set the connection configuration tag after advertising init with ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);, where APP_BLE_CONN_CFG_TAG should correspond with the tag used by ble_stack_init()->nrf_sdh_ble_default_cfg_set().

Best regards,

Hi Vidar,

Could you explain it in more detail? I still don't know how to fix it.

Thank you very much.

Hi Ted,

Are you able to upload a minimal version your project so I can try it here?

Hi Vidar,

I have solve this issue.

Thank you very much.
