hoi,
ik werk sinds kort met linux mint 18.3 kde, wat mij zeer goed bevalt maar ik krijg mijn bluetooth niet in orde. De installatie is wel gelukt... denk ik maar ik kan apparaten vinden. Na wat gegoogle is volgende info voor een oplossing te zoeken belangrijk denk ik... Kan er hier iemand mij verder helpen ?? ( ... van programmeren e.d. ken ik niets...
)
mark@mark-HP-Pavilion-17-Notebook-PC ~ $ lsusb |grep Bluetooth
merci.

[ 7.442682] bluetooth hci0: Direct firmware load for brcm/BCM.hcd failed with error -2
You need the firmware for that Broadcom Bluetooth device. Here's a prior forum post with instructions. Use the terminal commands there and post back if you have any problems.

If you run the following command from Terminal and copy-paste back the results, it should show if the broadcom firmware file was copied to the folder.

Code: Select all
wget https://www.dropbox.com/s/r6q9zt59darq80n/BCM43142A0-0a5c-216c.hcd
sudo cp BCM43142A0-0a5c-216c.hcd /lib/firmware/brcm/BCM.hcd
sudo modprobe -r btusb
sudo modprobe btusb
You may have to power off the computer and boot

ark@mark-HP-Pavilion-17-Notebook-PC ~ $ ls -a /lib/firmware/brcmBCM-final.hcd brcmfmac43241b4-sdio.bin brcmfmac4334-sdio.bin brcmfmac4350c2-pcie.bin brcmfmac43570-pcie.binBCM.hcd brcmfmac43241b5-sdio.bin brcmfmac4335-sdio.bin brcmfmac4350-pcie.bin brcmfmac4358-pcie.bin
OK, file is there and I marked it with color Blue. I see where prior attempt was wrong file name and marked it with color Red.
Have you tried a reboot of system?

Need to ask you which kernel you are running, as I've been checking on file name issues.
If you run the following command from terminal, it will provide the kernel version.
The reason I'm asking is due to file naming requirement may operate differently with different kernel versions. This article at ubuntu explains.

I've been assuming that the error message showing missing file BCM.hcd was correct for name. The article helps explain why Broadcom Bluetooth is a complicated problem.

Some of these bluetooth devices have had issues loading firmware recently, I would just remove the fiirmware wit
Code: Select all
sudo rm /lib/firmware/brcm/BCM.hcd
You might be able to find a different hex file from the Windows driver to convert so it can be used in Linux by seeing
