ble_advdata_set deprecated

[Juan Moya]

Hello,

I am trying to move the

err_code = ble_advdata_set(&advdata, NULL);

 return err_code;

Looking the documentation the new functions to update the advertisment are:

 ret = ble_advdata_encode(&advdata_, new_advdata.adv_data.p_data, &new_advdata.adv_data.len);
    APP_ERROR_CHECK(ret);
     
        
 ret = sd_ble_gap_adv_set_configure(&(m_advertising).adv_handle, &new_advdata, NULL);
    APP_ERROR_CHECK(ret);

But I don't undestand how use it to modify the 0xFF type data,...

I am trying with a function like this:

uint32_t _ble_update_manuf_specific_data( uint16_t vSize, uint8_t * vData ){
    uint32_t err_code;
        
        ble_gap_adv_data_t     new_advdata;
        ble_advdata_t             adver_data;
    
        memset(&new_advdata, 0, sizeof(new_advdata));
        memset(&adver_data, 0, sizeof(adver_data));
    
        adver_data.name_type                       = BLE_ADVDATA_FULL_NAME;
    adver_data.include_appearance              = true;
    adver_data.flags                           = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
    adver_data.uuids_complete.uuid_cnt         = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
    adver_data.uuids_complete.p_uuids          = m_adv_uuids;
            
        adver_data.p_manuf_specific_data           = &m_manuf_specific_data;
        m_manuf_specific_data.data.p_data         = m_manuf_data_array;
    
        adver_data.p_manuf_specific_data->company_identifier = LULABYTES_ID;
        adver_data.p_manuf_specific_data->data.size                     = vSize;        
        for(uint32_t i = 0; i < vSize; i++){ m_manuf_data_array[i] = vData[i];    }    

          

    err_code = ble_advdata_encode(&adver_data, &(new_advdata->adver_data.p_data), &(new_advdata->adver_data.len));
    APP_ERROR_CHECK(err_code);
    
        err_code = sd_ble_gap_adv_set_configure(&(m_advertising).adv_handle, &new_advdata, NULL);
    APP_ERROR_CHECK(err_code);
    
    return err_code;
}

But it has errors.

Hi!

Maybe you could provide some more specific information?

In general it is very often useful to include a little information about your setup; SDK version, which device, Softdevice version etc.

As for your issue "But it has errors"; could you include some information about which function returns the error code? What error code is returned?
This makes is a lot easier to figure out what the problem is.

Best regards,
Joakim.

Hello!!

I'm using nRF5_SDK_15.0.0_a53641a

I would like to modify the advertise frame every 5 seconds.

I was using this code to modify:

uint32_t _ble_update_manuf_specific_data( uint16_t vSize, uint8_t * vData ){
    uint32_t err_code;
        
        
        advdata.p_manuf_specific_data                                       = &m_manuf_specific_data;
        m_manuf_specific_data.data.p_data                                 = m_manuf_data_array;
    
        advdata.p_manuf_specific_data->company_identifier = LULABYTES_ID;
        advdata.p_manuf_specific_data->data.size                     = vSize;        
        for(uint32_t i = 0; i < vSize; i++){
                m_manuf_data_array[i] = vData[i];
        }
    
    
    err_code = ble_advdata_set(&advdata, NULL);
    return err_code;
}

But in this new version, the function ble_advdata_set is deprecated.

So I would like to know how can modify this information. I found an example in the forum but it doesn't work.

Best regards,

Juan

Hello,

Using this function:
uint32_t advertising_data_update(uint8_t adv_manuf_byte){
    
      uint32_t ret = NRF_SUCCESS;
    ret_code_t err_code;
    ble_advdata_t                                  advdata;       /**< Advertising data: name, appearance, discovery flags, and more. */
    //ble_advdata_t                              srdata;        /**< Scan response data: Supplement to advertising data. */

        uint8_array_t                                    adv_manuf_data_array;
        uint8_t                                          adv_manuf_data_data[2] = {0x00,0x0B};
        ble_advdata_manuf_data_t                         adv_manuf_data;
        adv_manuf_data_data[0]                         = adv_manuf_byte;
    
    memset(&advdata, 0, sizeof(advdata));
    //memset(&srdata, 0, sizeof(srdata));
   
    advdata.name_type                      = BLE_ADVDATA_FULL_NAME;
    advdata.include_appearance             = false;
    advdata.flags                          = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;//BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;
    advdata.uuids_complete.uuid_cnt     = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
    advdata.uuids_complete.p_uuids      = m_adv_uuids;
        
        adv_manuf_data.company_identifier   = LULABYTES_ID;
        adv_manuf_data_array.p_data         = adv_manuf_data_data;
        adv_manuf_data_array.size                     = sizeof(adv_manuf_data_data);
        adv_manuf_data.data                                 = adv_manuf_data_array;
        advdata.p_manuf_specific_data             = &adv_manuf_data;

    ret = update_advertising_data(&m_advertising, &advdata, m_advertising.adv_data.adv_data.len +1, NULL, 0);
        
        return ret;
}


uint32_t 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;
    uint8_t buffer[adv_data_len];
    memset(buffer, 0, adv_data_len);
    
    ble_gap_adv_data_t new_advdata;
    memset(&new_advdata, 0, sizeof(new_advdata));
    new_advdata.adv_data.p_data = buffer;
    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);
        
        return ret;
}

The first time that I call it I have Error Code 0, but the second time I get the ERROR CODE 8.

Best regards,

Juan

Hi again.

Have you seen this post?
https://devzone.nordicsemi.com/f/nordic-q-a/33606/updating-advertising-data-manuf-spec-data-in-sdk15

This contains a long discussion, suggestions on how to do this, and workarounds for updating the advertisement data.

If you haven't already, please take a look at the post.
Please get back to me and let me know if you are not able find any useful information.

Best regards,
Joakim
