Hi Markus

In that case, I don't think we'll be able to help you, as there is no way to "forbid" the SoftDevice from sending a scan response when a request is received.

Best regards,

Simon

Hi Simonr,

I never has use the whitelist but im correct that only Centrals can connect which are within that whitelist? At the end we will have some special central's which will connect to our Tag but we will never know the address on our Tags

Hi Markus

In order to disable the scan responses completely, you will have to use the whitelist advertisement feature, as per the core spec "The Host shall set the advertising filter policy to 'process scan and connection requests from all devices'." It is common that the scanner will ignore advertisers that don't respond to scan requests, which is why the scan response replies with an empty data packet.

You can check out this thread which has a great discussion on the matter.

Best regards,

Simon

Not sure would it help or not but I'd try to set scan response data pointer to NULL manually after calling ble_advertising_init() function.

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

m_advertising.adv_data.scan_rsp_data.len = 0;
m_advertising.adv_data.scan_rsp_data.p_data = NULL;

Hello,

Have you tried to set ble_adv_extended_enabled flag to false ?

Like this:

  ble_advertising_init_t init;
  
  init.config.ble_adv_extended_enabled = false;
