Problem getting my computer's Bluetooth working

[Usr1]

Hi, i am having a problem getting my computer’s Bluetooth working. The Bluetooth was working fine when i was using Ubuntu. Here is my hardware details:

HW probe of Dell Inspiron 15-3567 #c8723d2dd9

Scroll down and you will see that the bluetooth marked is light red.
Here is the drivers list:

Qualcomm Atheros Communications Qualcomm Atheros Bluetooth Device

I think that the driver is installed on my system.
I did:
modinfo ath3k
and the output:

I appreciate any help. Thanks.

Have a look at the latter parts of this thread:

Bluetooth not working out of the box

You can download and install it manually. https://packages.debian.org/stretch/all/firmware-atheros/download You’ll have to update it manually, though.

That helped a lots, thanks

Bluetooth not working out of the box

Thanks. For those who will join this thread in the future (and they will until BT is available out of the box): In the end I went with adding deb http://deb.debian.org/debian bullseye non-free to the (PureOS byzantium and Debian bullseye-backports main) repo list, and using the Synaptic package manager to install just that single package from outside the Byzantium/Bullseye main structure. This has pulled in the most recent (stable) version from bullseye (20210315-3) as opposed the one mentio…

[jvoros]

Glad to hear it That was the idea

[Usr1]

That package firmware-atheros is not free and open-source, right ? Is that the reason why purism does not have it in their repos ?

[jvoros]

Right. The very earliest part of the thread quoted above goes into the ins and outs of that. It seems no-one has (yet) stepped up to produce a suitably FOSS Bluetooth driver, hence the need to utilise the non-free section of the debian repo.
