Bluetooth Dongle for Ageing Linux Laptop

[doctormann]

I just updated my old Lenovo Ideapad Z370 from Mint 20.3 to Mint 22 as support for 20.3 will end fairly soon.

 

Most things seem to work OK, although some software packages that I was using are no longer available.  I've found substitutes for just about everything but I can't get Bluetooth to work.  It may be that the Mint 22 kernel is not fully compatible with my hardware.  I have purchased a Bluetooth dongle - very cheap. CSR 4.0 - that according to reviews is supposed to be Linux compatible.  No joy - the system recognizes the dongle but it doesn't connect.

 

So, the question is, has anyone out there found a Linux compatible Bluetooth dongle that actually works out of the box?

 

I don't really use Bluetooth very much but it would be nice to have it.  The laptop will be replaced soon anyway so it's not a big deal.

 

Any help or suggestions would be much appreciated.

Mint 20.x doesn't natively support the drivers necessary to use the dongle and trying to install the necessary drivers is a PITA. Speaking from experience.  LM 22 works just dandy.  Upgrade on you're gold.

This one will work TP-Link-UB500.  ฿239  There is "cheap" and there is really "cheap." When really cheap doesn't work, quality is the issue.  A CSR 4.0 is like ฿49.  You got what you paid for.  Shell out $7 bucks and get one that is both cheap inexpensive and of known quality. A TP-Link device is going to work if your system supports the drivers.

Thanks for the reply.  I might just speculate the 239 Baht on the TP-Link dongle.  I'm not sure if the system supports the drivers or not.  Probably worth the risk though.

The laptop certainly has Bluetooth support - worked perfectly on Mint 20.3, using the built-in adapter.
