I should add that 'lsusb' shows the device is: Bus 001 Device 004: ID 0a5c:21d7 Broadcom Corp. BCM43142 Bluetooth 4.0
The USB vendor:device ID is 0a5c:21d7 and I see in the github repository the file: brcm/BCM43142A0-0a5c-21d7.hcd so you should be able to install it using: sudo wget -O /lib/firmware/brcm/BCM.hcd https://github.com/winterheart /broadcom-bt-firmware/blob/master/brcm/BCM43142A0-0a5c-21d7.hcd After a reboot the Bluetooth device should work. ** Package changed: bluez (Ubuntu) => linux (Ubuntu) ** Summary changed: - bluetooth devices are not getting found + Broadcom Bluetooth brcm/BCM.hcd firmware not found -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1743336 Title: Broadcom Bluetooth brcm/BCM.hcd firmware not found Status in linux package in Ubuntu: Confirmed Bug description: bluetooth device search not working.
