Bluetooth devices not found

[chelo]

Hello there,
I have installed linux mint 21 on my laptop (HP ENVY TS 15 Notebook PC).
My problem is that it doesn't find bluetooth devices. I just try

Code: Select all

sudo dmesg | grep -i bluetooth | grep -i firmware

but not working.

Run <sudo lshw> in a terminal - look for usb controlller for bluetooth and post here

Example output:

The output does not say Bluetooth anywhere.
I.E. *-usb:1 description: Bluetooth wireless interface

Did Bluetooth previously work? Does the Bluetooth work with another OS or on the Mint USB install? Are you sure your laptop has Bluetooth? It may not have a Bluetooth device or the device may not be working. You may need a Bluetooth dongle. Maybe someone else can give you more help.

Hmm.

lsusb shows your Bluetooth adapter:

Bus 003 Device 004: ID 0a5c:21fb Broadcom Corp. BCM20702A0

and

rfkill list all shows that it's not switched off by hardware or software.

Someone with experience with Bluetooth will have to come along and advise. The forum has a few experts on it. Sorry I couldn't help.

If it will be interesting, wifi not working also and I'm using wired connection.

I have had a Broadcom driver before and have had issues as it is proprietary. I do not have Broadcom now, but here is a list of Broadcom drivers in Synaptic, I am not seeing support for your Broadcom Corp. BCM20702A0 device but only for BCM43????.

BCM20702A0 as all seem to be for

These post may help you:

echo "19ff 0239" >> /sys/bus/usb/drivers/btusb/new_id
fixed it.

From this forum:

[solved] Unable to get bluetooth adapter BCM20702A0 up and running

It seems to have problems on Kali and Arch also. Try this search if the other two fail, there are a lot more posts, some about kernel patches.
enter <Broadcom Corp. BCM20702A0 supported for Linux> in the search box.
Again maybe someone with more experience will be willing to help.
