Broadcom bluetooth problem

Bluetooth functions fine with a USB bluetooth dongle plugged in. I can’t get the internal Broadcom bluetooth to function though - it cannot be turned on using the Settings app (whose window remains empty). I think I need firmware for it. The Broadcom chip I think is both wifi and bluetooth. Wifi is working fine.

Budgie 18.04 64 bit
Broadcom BCM2046B1

Bus 003 Device 014: ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth)

dmesg | grep -i blue
[ 7921.131683] Bluetooth: Core ver 2.22
[ 7921.131735] Bluetooth: HCI device and connection manager initialized
[ 7921.131744] Bluetooth: HCI socket layer initialized
[ 7921.131748] Bluetooth: L2CAP socket layer initialized
[ 7921.131762] Bluetooth: SCO socket layer initialized

sudo rfkill list
1: compal-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no

sudo service bluetooth status
This confirms that the service is running - though I already know this as the USB dongle works.

I installed Ubuntu Budgie desktop from standard Ubuntu 19.04. Budgie flies compared to the standard Ubuntu. I had exactly the same Broadcom bluetooth problem with standard Ubuntu of course.

An help would be appreciated - particularly to get the necessary firmware.

Hi and welcome

This is more of a generic question readily answerable through the wider ubuntu community forums and

Having said that, this thread looks interesting since it is your chip

Thanks for that - I’ll try over there.
