Updating advertising data (manuf. spec. data) in SDK15

Hello guys! And girls 

My project is working as expected in SDK14.2.
I'm updating adv data (manuf. spec. data) without any problem with this function

static void advertising_data_update(uint8_t adv_manuf_byte)
{
		ret_code_t err_code;

		ble_advertising_init_t 		init;
		ble_advdata_manuf_data_t 	adv_manuf_data;
		uint8_array_t            	adv_manuf_data_array;
		uint8_t                  	adv_manuf_data_data[1];
		adv_manuf_data_data[0] 		= adv_manuf_byte;

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

		init.advdata.name_type          		 = BLE_ADVDATA_FULL_NAME;
		init.advdata.include_appearance 		 = false;
		init.advdata.flags              		 = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
		init.advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
		init.advdata.uuids_complete.p_uuids  = m_adv_uuids;

		adv_manuf_data_array.p_data 							 = adv_manuf_data_data;
		adv_manuf_data_array.size 								 = sizeof(adv_manuf_data_data);
		adv_manuf_data.company_identifier 				 = APP_COMPANY_IDENTIFIER;
		adv_manuf_data.data 											 = adv_manuf_data_array;
		init.advdata.p_manuf_specific_data 				 = &adv_manuf_data;

		init.config.ble_adv_whitelist_enabled      = true;
		init.config.ble_adv_directed_enabled       = true;
		init.config.ble_adv_directed_slow_enabled  = false;
		init.config.ble_adv_directed_slow_interval = 0;
		init.config.ble_adv_directed_slow_timeout  = 0;
		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;
							
		err_code = ble_advdata_set(&init.advdata, NULL);
		APP_ERROR_CHECK(err_code);	   
}


But in SDK15 the function ble_advdata_set() has been deprecated.
The migration guide is says to use ble_advdata_encode() and sd_ble_gap_adv_set_configure() instead.

So I changed it to something like this

static void advertising_data_update(uint8_t adv_manuf_byte)
{
		ret_code_t err_code;

		ble_advertising_init_t 		init;
		ble_advdata_manuf_data_t 	adv_manuf_data;
		uint8_array_t            	adv_manuf_data_array;
		adv_manuf_data_data[0] 		= adv_manuf_byte;

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

    init.advdata.name_type          		 = BLE_ADVDATA_FULL_NAME;
    init.advdata.include_appearance 		 = false;
    init.advdata.flags              		 = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;
    init.advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
    init.advdata.uuids_complete.p_uuids  = m_adv_uuids;
			
		adv_manuf_data_array.p_data 							 = adv_manuf_data_data;
		adv_manuf_data_array.size 								 = sizeof(adv_manuf_data_data);
		adv_manuf_data.company_identifier 				 = APP_COMPANY_IDENTIFIER;
		adv_manuf_data.data 											 = adv_manuf_data_array;
		init.advdata.p_manuf_specific_data 				 = &adv_manuf_data;

    init.config.ble_adv_whitelist_enabled      			= true;
		init.config.ble_adv_directed_high_duty_enabled 	= true;
    init.config.ble_adv_directed_enabled       			= false;
    init.config.ble_adv_fast_enabled  				 			= true;
    init.config.ble_adv_fast_interval 				 			= APP_ADV_INTERVAL;
    init.config.ble_adv_fast_timeout  				 			= APP_ADV_FAST_DURATION;

		//err_code = sd_ble_gap_adv_stop(m_advertising.adv_handle);
		//APP_ERROR_CHECK(err_code);
			
		err_code = ble_advdata_encode(&init.advdata, m_adv_data.adv_data.p_data, &m_adv_data.adv_data.len);	
		APP_ERROR_CHECK(err_code);

		err_code = sd_ble_gap_adv_set_configure(&m_advertising.adv_handle, &m_adv_data, NULL);
		APP_ERROR_CHECK(err_code);
		
		//err_code = sd_ble_gap_adv_start(m_advertising.adv_handle, APP_BLE_CONN_CFG_TAG);
		//APP_ERROR_CHECK(err_code);
}


And of course... it's not working. :)
I'm getting a very strange error at sd_ble_gap_adv_set_configure() --> app: ERROR 12801 [Unknown error code]

Any idea why?
What I'm doing wrong?
What I have to change to get this working like in the SDK14.2?

  • I understand your confusion, the new APIs can be confusing at first. A colleague has made a function to demonstrate how it should be done:

    /* PARAMS
    [IN] p_advertising: Pointer to an advertising instance, usually m_advertising in 'main' context.
    [IN] p_adv_data:    Pointer to an advertisment data instance.
    [IN] adv_data_len:  Length of advertisment data in bytes.
    [IN] p_sr_data:     Pointer to an scan respose data instance, set to NULL if no SR data.
    [IN] sr_data_len:   Length of scan response data in bytes.
    */
    void update_advertising_data(ble_advertising_t *p_advertising, ble_advdata_t *p_adv_data, uint16_t adv_data_len, ble_advdata_t *p_sr_data, uint16_t sr_data_len)
    {
        ASSERT(p_advertising->initialized);
    
        uint32_t ret = NRF_SUCCESS;
        ble_gap_adv_data_t *new_advdata;
    
        new_advdata->adv_data.len = adv_data_len;      
    
        ret = ble_advdata_encode(p_adv_data, new_advdata->adv_data.p_data, &new_advdata->adv_data.len);
        APP_ERROR_CHECK(ret);
    
        if (p_sr_data)
        {
            new_advdata->scan_rsp_data.len = sr_data_len;
    
            ret = ble_advdata_encode(p_sr_data,
                                   new_advdata->scan_rsp_data.p_data,
                                   &new_advdata->scan_rsp_data.len);
            APP_ERROR_CHECK(ret);
        }
        else
        {
            new_advdata->scan_rsp_data.p_data = NULL;
            new_advdata->scan_rsp_data.len    = 0;
        }
    
        ret = sd_ble_gap_adv_set_configure(&p_advertising->adv_handle, new_advdata, NULL);
        APP_ERROR_CHECK(ret);
    }
    

    I've not been able to test it, but I believe this function will operate as intended.
