Hello everyone,
I would like to update my advertising data on the fly but actually it doesn't work. Some posts talk about this behaviour but no real answers.
Here's my code :
static void update_advertising_data (uint8_t* p_user_data,uint8_t len_user_data){
ble_advdata_manuf_data_t manuf_specific_data;
ble_advdata_t advdata;
memset(&manuf_specific_data, 0, sizeof(manuf_specific_data));
manuf_specific_data.company_identifier = APP_COMPANY_IDENTIFIER;
manuf_specific_data.data.p_data = (uint8_t *) p_user_data;
manuf_specific_data.data.size = len_user_data;
// Build and set advertising data.
memset(&advdata, 0, sizeof(advdata));
advdata.name_type = BLE_ADVDATA_FULL_NAME;
//advdata.short_name_len = strlen(DEVICE_NAME)-3;
advdata.flags = BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED;
advdata.p_manuf_specific_data = &manuf_specific_data;
uint32_t err_code = ble_advdata_encode(&advdata, m_adv_data2.adv_data.p_data ,&m_adv_data2.adv_data.len);//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_adv_handle, &m_adv_data2, NULL);
APP_ERROR_CHECK(err_code);
}
I see that and I need to respect that :
In order to update advertising data while advertising, new advertising buffers must be provided. => I use a new buffer (m_adv_data2)
Provide a pointer to an existing advertising handle to configure an existing advertising set => I KEEP THE SAME HANDLE SINCE THE BEGINNING
When this function is used to update advertising data while advertising,this parameter must be NULL. => sd_ble_gap_adv_set_configure PARAMETER 3 IS SET TO NULL
The result is an error and no data updated ...
The error I get is the following : sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data2, NULL); return => 0X08
Hope anyone could help me.
Kind regards,
Sylvain.
