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.

This seems like a good resource for main components, I’ll definitely use it when I upgrade. Seems like for dongles I should need to know the chipset which is not listed on store pages.
