Bluetooth doesn't work with Ubuntu 18.04 [BCM20702A1-13d3-3411]
I installed Ubuntu 18.04 in my Alienware 17, everything is running fine except the Bluetooth. It's active but I can't connect with my headphones, telephone and mouse.
sudo dmesg | grep -i bluetooth

Try executing the following command in the terminal.
This will download the Broadcom Bluetooth firmware for Linux kernel to /lib/firmware/brcm.
sudo wget --tries=3 --timeout=120 -P /lib/firmware/brcmAfter installing the firmware, simply reboot to load the driver.
