I installed the wireless driver using this instruction How do I install BCM43142 wireless drivers for Dell Vostro 3460/3560 and I have WiFi working. No problems here.
But unfortunately the bluetooth doesn't work. The ubuntu bar shows the bluetooth sign and I can turn the bluetooth on/off but I can't discover any devices. And I can't find my laptop when I turn visibility On. So, obviously bluetooth doesn't work.
I couldn't find the reports that blutooth can actually work with this adapter in Ubuntu. So, my question is: Is there anyone with BCM43142 adapter that have bluetooth working?
Thank You in advance.
PS. Ubuntu 12.10 x64
After some fiddling around with different drivers from different sources I managed to get bluetooth working. Not flawlessly but at least I can pair a device. Bluetooth started working after installation of this package bt-bcm43142-onereic_0.0+20111116somerville2_amd64.deb Originally I found this package on the disk with Ubuntu which came with the Laptop. What this package does, it installs a firmware loader and a firmware itself. This firmware needs to get bluetooth working.
Still bluetooth sometimes doesn't work even with this package. But manual loading the firmware helps.
brcm_patchram_plus_usb --patchram /lib/firmware/BCM43142A0_001.001.011.0028.0036.hcd hci0
Also I found it strange that this package writes all different ids into /sys/bus/usb/drivers/btusb/new_id because only one from the list matches my device ID
install btusb /sbin/modprobe --ignore-install btusb && echo '0a5c 21d3' > /sys/bus/usb/drivers/btusb/new_id && echo '0a5c 21d7' > /sys/bus/usb/drivers/btusb/new_id && echo '0a5c 21e1' > /sys/bus/usb/drivers/btusb/new_id && echo '0a5c 21e3' > /sys/bus/usb/drivers/btusb/new_id && hciconfig hci0 up && /usr/bin/brcm_patchram_plus_usb --patchram /lib/firmware/BCM43142A0_001.001.011.0028.0036.hcd hci0 &
... Bus 002 Device 003: ID 0a5c:21d7 Broadcom Corp.
In conclusion: bluetooth works not nearly as good as in windows :( once I even got a complete crash of the system because of the btusb module. Luckily WiFi works perfectly :)
