Broadcom bluetooth no adapters found

#1 Post by TopKek »

Hello, I've been trying to get bluetooth to work for the past couple days now on a new Debian 9.1 install. I installed the correct Broadcom bluetooth firmware (mine being BCM20702A1-0a5c-21f1.hcd) to /lib/firmware/brcm.
Using

Code: Select all

dmesg | grep -i blue
it looks like it does load the firmware.

Code: Select all

However, in KDE, it reports "No Bluetooth adapters have been found." in bluetooth system settings.

Maybe try backporting a more recent kernel. If this does not work, you may be out of luck.

Edit: Second option, at own risk.

Code: Select all

# apt-get install build-essential git
# git clone https://github.com/jeremyb31/bluetooth-4.8.git
# cd bluetooth-4.8
# cp /usr/src/linux-headers-$(uname -r)/.config ./
# cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
# make -C /lib/modules/$(uname -r)/build M=$(pwd) modules
# cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
# depmod -a && reboot

Hallvor suggested trying a newer kernel, did that work for you?
