[SOLVED] Sonya on Tablet No Bluetooth Adapters found

[plawrence50]

I have installed Sonya on a Fujitsu Tablet (came with Win 8.1) which has a network card BCM43241b4. I managed to get the WiFi working after installing the file brcmfmac43241b4-sdio.txt into /lib/firmware/brcm. This card should support Bluetooth as well as WiFi, but BT doesn't work due to the error "No Bluetooth Adapters found".

I found a DELL website with firmware for the BCM43421 which supports WiFi and BT but it is for Windows only. I believe the problem may be the firmware file that ships with Mint 18.2 does not allow BT.

Does anyone know of a firmware file for Linux which will allow WiFi and BT? Or does anyone have any other suggestions that I can try?

Thanks for any pointers

I would use the Update Manager using the view/linux kernel menu to install the newest kernel available(4.11.0?) then reboot and see if it works. I have no idea what is required to get the SDIO bluetooth chipsets working as I am more familiar with the USB bluetooth

Thanks for the suggestion , I will give it a try.

Installed latest kernel, but still no bluetooth adapters.
~ $ uname -r
4.12.6-041206-generic

See if

Code: Select all

dmesg | egrep -i 'blue|firm'

Shows us any errors or clues as you may need firmware

[plawrence50]

See output of dmesg, the firmware version does look a little old. I will try to get a later version of Broadcom software from a Windows vendor, break it open and convert the firmware file to a format that Linux can use - I have seen a method for doing this .

Maybe you can snoop through the /sys/bus/sdio directory and see what you find in the subdirectories modalias file, the problem might be that the kernel needs another device added to the source code. Broadcom's vendor ID is 02d0

[plawrence50]

hi,

Poking into the /sys/bus/sdio directory show what looks like 2 devices (the :1 and the :2) but a single driver - brcmfmac. Each of the devices, if that is what they are, have the same modalias.

Code: Select all

> ls /sys/bus/sdio
devices  drivers  drivers_autoprobe  drivers_probe  uevent
 ls /sys/bus/sdio/drivers
brcmfmac
>  ls /sys/bus/sdio/devices/
mmc1:0001:1  mmc1:0001:2
>  ls /sys/bus/sdio/devices/mmc1*
/sys/bus/sdio/devices/mmc1:0001:1:
class  device  driver  firmware_node  ieee80211  modalias  net  power  subsystem  uevent  vendor

/sys/bus/sdio/devices/mmc1:0001:2:
class  device  driver  firmware_node  modalias  power  subsystem  uevent  vendor
> cat /sys/bus/sdio/devices/mmc1:0001:1/modalias
sdio:c00v02D0d4324
> cat /sys/bus/sdio/devices/mmc1:0001:2/modalias
sdio:c00v02D0d4324

I am not sure what this is telling me, but I think I will forget about Bluetooth for the moment.

I did not go down the Windows firmware route as the driver is not complaining about any missing firmware file.

Thank you for your assistance, I guess we can close this thread.

See what happens

Code: Select all

btattach --bredr /dev/ttyS1 -P bcm

Then check

Code: Select all

dmesg | tail -20

Here goes:

Solved...
The guys on linuxium are doing some good work on putting Ubuntu onto Intel Atom and have a script for grabbing the latest Broadcom drivers:

linuxium-install-broadcom-drivers.sh

After installing the latest Broadcom driver I then got a line in dmesg about a missing firmware file BCM4342B3.hcd which I then downloaded from Sourceforge and now Bluetooth is working.
