Can you recommend a Bluetooth dongle that support s version 5.3, not too terribly expensive and available in Europe? Preferably works out of the box on Ubuntu LTS, but compiling my own kernel is also acceptable.
For context my last attempt ended with one that only works with Windows 10, when no other Bluetooth receiver is connected. Cherry on top it needs troubleshooting wizard after each reboot.
Does your laptop have a replaceable wireless card by chance? Could get a combo board with wifi and bluetooth like the intel ax series of boards if you can. I use a m.2 ax200 in my desktop.
It’s a desktop and it’s too old to have m.2. However thanks for the suggestion, it’s something I’ll consider when I upgrade
If your system has a free PCIe slot you should be able to find a wifi card that will work. I personally am using an intel wifi board for bluetooth and have not had any problems with bluetooth. Their driver seems to be really stable on linux and in kernel and should be stable on windows as well. I got my m.2 card for about $20(usd) and wouldn’t expect that big of a difference for a standard PCIe card.
Good luck in whatever you end up doing.
I believe there are m.2 to pcie adapter boards. It’ll feel weird putting laptop components in a desktop, but the important thing will be that it works.
You know what is weird selling desktop components which are laptop components with an adapter https://www.asus.com/networking-iot-servers/adapters/all-series/pce-ax1800/
I can really recommend those cards! They come in several sizes for laptop and desktop. I am not sure about USB. Just make sure you get the regular PCIe version and not the CNVio version (unless you have a compatible Intel Mainboard and somewhat recent processor). They differ in the naming, e.g. AX210/AX211 if I remember that right.
