Radiotap headers supported with WICED ?

[MiTo_1583836]

Hello,

Is it possible to confirm if the radiotap headers are supported by WICED ? Radiotap - Defined Fields

If yes, is there a document or file that would provide a list of the ones that are defined and available?

Radiotop headers are not standard and may or may not be available. I understand this is based on the driver as well as the radio. I am thinking Broadcom/Cypress may have carried the information one way or another, just need some confirmation.

Thank you!

May I know the Wi-Fi chip that you are using? I could only find information on radiotap headers in /43xxx_Wi-Fi/libraries/test/wl_tool/43012C0/shared/bcmwifi/src/bcmwifi_radiotap.c. Also why do you need radiotap headers? Please elaborate your requirement.

Thanks for the reply. I do not have the path mentioned above in the 5.1 SDK. The 43012C0 is not listed. The only file that I can find on radio tap is under: ./43xxx_Wi-Fi/WICED/platform/MCU/BCM4390x/peripherals/include/proto/ieee80211_radiotap.h

I think at this point we are trying to interpret the extra data coming back from the radio. There are extra bytes that have been identified as radio tap information and we are trying to figure out the meaning of it.

I just need to know if the file above is the only information available currently on this.

Any extra information is welcome.

Thank you!

It's in SDK-5.2.0.

The radiotap fields are defined in ieee80211_radiotap.h. If you are using WICED SDK 6.0, there are functions defined in \libraries\test\wl_tool\43012C0\shared\bcmwifi\src\bcmwifi_radiotap.c for parsing.

Hi grsr​

The file is not available in the latest SDK (see picture). I also ran a search on the whole folder for the bcmwifi_radiotap.c it is nowhere to be found (see picture). The 43012C0 is removed from the folder.

I still can find the header file in: /WICED/platform/MCU/BCM4390x/peripherals/include/proto/ieee80211_radiotap.h

Would you be able to send me this bcmwifi_radiotap.c file?

Your initial statement appears to assume the user has the Early Adopter version of the SDK as the 43012 is not supported in the broad market today.

I checked WICED Studio 6.0 which is available to the community and found that the information for radiotap headers is only found in \WICED\platform\MCU\BCM4390x\peripherals\include\proto\ieee80211_radiotap.h. The WICED SDK version in which I checked previously is not available to the broad market.

Radiotap headers are not supported within the Broad Market.

Actually, the libraries/test/wl_tool/43012C0/shared/bcmwifi/src/bcmwifi_radiotap.c

is in sdk-5.2 (As I mentined in previous post).

Somehow, it's no longer exist in sdk-6.0.x.
