03:00.0 Network controller [0280]: Broadcom Corporation BCM4331
802.11a/b/g/n [14e4:4331] (rev 02)
Subsystem: Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331]
[...snip...]
Kernel driver in use: bcma-pci-bridge
Kernel modules: bcma
lspci doesn't list Bluetooth. I'm not sure what driver is being used,
but I suspect one of these:
btusb 45056 0
snd_hda_codec_hdmi 45056 1
btrtl 16384 1 btusb
btbcm 16384 1 btusb
btintel 16384 1 btusb
bluetooth 491520 36 bnep,hidp,btbcm,btrtl,btusb,rfcomm,btintel
It looks like bluetooth module just drags in generic, Intel, Broadcom,
and Realtek device drivers, whether the hardware is present or not.
I was almost ready to give up on b43/bcma because I don't get even get
802.11n support with that driver. What I found on Broadcom's site for
Linux is hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz but I haven't
gone down that rabbit hole yet.
Try doing googling for this issue. I looked and the bcma driver doesn't
have a bluetooth co-exist flag like the iwlwifi does. I was going to
suggest making sure that was on, but since I don't see that option it'd
be useless.
According to Broadcom:
Do Bluetooth wireless technology and IEEE 802.11 interfere with each other?
Bluetooth wireless technology and 802.11b/g both use the 2.4 GHz ISM
(Industrial, Scientific, Medical) unlicensed spectrum, and in some
configurations can interfere with each other. If the Bluetooth and
802.11b/g antennas are more than 3 meters apart, however, interface in
minimal. Co-existence schemes such as adaptive frequency hopping have
been implemented to address potential interference issues and Broadcom
has introduced its InConcert® coexistence technology, which mitigates
interference problems.
Hmmm. Apparently not in your case. Sorry.
