Parsing scan response with SDK 15.3

[Lorenzo]

Hi everybody,

I am using nRF52832/40 with SDK 15.3 and softdevices S132/S140 v6.1.1.

One of my devices is performing active scanning, therefore sending scan requests, and the other one is replying with scan responses.

I can see clearly that this is happeing correctly using your BLE sniffer for Wireshark (btw, great tool!).

I am able to set the scan request and parse it on the peripheral side.

I am able to set the scan response, but I'm not able to parse it on the central side, and this is what I'd like to do. 

This is a snippet from my code:

{

if (p_adv_report->type.scan_response)

{

// Parse scan response packet here

led_blink(2,1,200); //This is just for debugging

}

else

{

// Parse advertising packet here

}

}

static void on_adv_report(ble_gap_evt_adv_report_t const * p_adv_report)
{
    if (p_adv_report->type.scan_response)
    {
        // Parse scan response packet here

        led_blink(2,1,200);  //This is just for debugging
    }

    else
    {
        // Parse advertising packet here
    }
}

It seems like I'm never entering the first if, where scan response packets should be handled, while I'm always entering the second one (for regular advertising packets).

What am I doing wrong?

Thank you very much!

Hi Lorenzo, 
I added this to the ble_app_multiplink_central: 

And I can see that it can catch some scan response packets: 

(I changed connect if match = false)

I attached the main.c file (I tested on SDK v15.2 but I don't think it would be much different to SDK v15.3)

Hi Hung, 

thanks. I removed the previous answer because I noticed that the modified ble_app_multilink_central was correctly showing scan responses.

Now I have to understand why I cannot catch them in my project. 

Thank you for your help! I'll keep you posted.
