CC3120: Capture probe request packets CC3120/CC3220

Hello,

I want to capture probe request packets using CC3120/CC3220.

Here is the similar question e2e.ti.com/.../354462

But CC3120 does not have sniffer example. And CC3120 SDK API does not have sl_WlanRxFilterSet() like CC3100 SDK only sl_WlanRxFilterAdd() function.

Is it possible to capture probe requests using CC3120 SDK?

Thanks.

Hello,

I need to listen to WiFi broadcasting messages from Phones and response from Access Point.
I want to capture this data:

I think I can get this information from probe request/response and beacon frame packages.

Best regards,
Michael

Hello,

I found that Transceiver mode can be used to capture all packages.

In my case i need only prob request and response.

Is it possible to apply some filters in RxFilters module to capture only this type of packages?

Thanks
