Broadcom 4330 and Intel Edison

[Domeika, Max J]

Hi,

  I could really use some help/expertise.

We are trying to get the Intel Edison which uses the Broadcom 4330 to act as both an AP and client at the same time. Iw list seems to suggest it is possible, but we haven?t figured out the correct process to do so or even if the underlying kernel will allow it (using ubilinux 3.10.17 and the driver is bcm43340-mod-1.141-r47.

Who could provide some expert advice/consultation?

Thanks and regards,

Max

It's some out-of-tree driver and BCM4330 is most likely a FullMAC
chip. It's not really related to b43 driver which support SoftMAC
devices.

bcm4330 is supported by the Linux upstream driver brcmfmac [0], you
could take brcmfmac from backports [1] and try if that driver supports
your requirements. BCM43340 seams to be a different chip, but it is also
supported by brcmfmac.

Doing AP+STA requires MBSS support, which 4330 firmware does not. At 
least not the one in linux-firmware repo.

Thanks. Sorry for the delay. Trying to learn enough to ask the right
questions. My read of this thread is that I could try brcmfmac from back
ports, but Arend is saying the firmware in the linux-firmware repo
wouldn't work anyways. Is that correct?

What it seems we really want is Wifi-direct support. Will the 4330
firmware in the repo support wifi-direct or is Wifi-direct also dependent
on MBSS?

Thanks,

Hi Max,

WFD aka P2P is supported by 4330 firmware in the linux-firmware repo. It 
does not depend on MBSS feature. Are you sure your system has 4330. The 
Intel Edison configuration I came across so far had 43340. What modalias 
does SDIO bus show for this device?
