蓝牙 BCM20702A1 不工作 - Ubuntu 16.04

蓝牙服务正在运行，但无法正常工作。我尝试过这些步骤适用于 BCM20702A1 (ID 105b:e066)，但不起作用。我注意到我的usb-devices产品上列出的是 Broadcom BCM20702A0，但上面lsusb显示的是 105b:e066 Foxconn International, Inc.

有任何想法吗？

答案1

这应该有效 

sudo 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
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo depmod -a

重新启动并查看是否有效

内核更新后，需要再次执行上述步骤 

cd bluetooth-4.8
make -C /lib/modules/$(uname -r)/build M=$(pwd) clean
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
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo depmod -a
重启
