Hi
I see on the "To be done list" for both the fullmac and softmac chips
is to add support for monitor mode. I was wondering how realistic is
that task. If it is definitely going to occur, any idea what it will
support, e.g. capturing management frames. Also any kind of hint what
kind of time frame are you looking at? Any info would be greatly
appreciated.
V/r,
Daniel Smith

For brcmsmac it has already been done just using the radiotap
functionality. I did not implement it, but I think this functionality is
provided by cfg80211. Not sure if that is sufficient info.

Hi,
I need to correct my words after some digging. The Android version does
*NOT* fully support monitor mode. It has some partial support there for
P2P implementation. But some packets are held by the dongle because of
filter offload. Sorry about the wrong info.

Hi Robert,
It's a firmware limitation instead of hardware to be more precise. There
is no firmware out there support monitor mode so the support can not be
done by changing the host driver only.

Thanks for the quick response and that is excellent to hear! Is there
any word on the fullmac side? I am actually interested in both as I
will be dealing with both standard and mobile devices. Due to the
popularity of your chips, it would be great if I could add Broadcom to
my list of viable chips.
Thanks!

Monitor mode is not supported in fullmac at the moment. I am afraid we
don't have an ETA as well. But if for mobile devices you mean Android
devices using Broadcom wifi chipset, current Android driver does have
monitor mode support.

Thanks for the answer!
I have read somewhere that the Broadcom 4330 chipset on Samsung Galaxy
S II cannot be put to monitor mode because of some hardware
limitation. Is that true? Can someone confirm that?

Hi,
Does that mean that the Android driver for bcm4330 has a working
monitor mode already? Where can I download that?

With fullmac chip management frames are normally not sent to the host so
there is a bit more work involved, but still realistic. At this moment I
can not really give a date when to expect it.

Hi,
Is there any hope in the near future for a brcm80211 firmware which
supports monitor mode? If I got it right, it is either Broadcom who
could release such a firmware or someone else who has infinite free
time to reverse engineer the blob firmware, right? Is there any
initiative for that? Maybe some progress on it? I ask it because I'd
like to contribute to such a project if it already exists.
Cheers,
Robert

There is no plan for adding monitor mode support since it's not
requested by any products. And it's impossible to release the firmware
source code at the moment. I am not aware of any reverse engineering
project for Broadcom fullmac dongle. However, I do plan to work on the
monitor mode support on the firmware for SDIO dongle as a leisure
project although I don't have a schedule for it. I will announce it on
the mail list when it's ready. Stay tuned :)

No, I still don't have time get to it.

Sorry, wrong answer. :(

Any news on this? :)
Seems like the Galaxy S3 uses BCM4330 as well.

Since there are no messages on this, I guess you did not get to start it?
There is a RE effort on https://code.google.com/p/bcmon/ that looks very
hacky.

The Samsung Galaxy S3 (i9300) uses BCM4334 (again SDIO interface, so fullmac).
I have not tested the brcmfmac driver, but if anyone tries to do so, you might
need the patch at http://marc.info/?l=linux-wireless&m=136881782700636.
