From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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.

Actually I haven't been able to get Bluetooth 5 dongles to work on Linux. I only have success with Bluetooth 4 dongles.

What are you going to use the Bluetooth dongle for? Connecting Bluetooth peripherals, or headphones? If it's exclusively for Bluetooth headphones, using a Bluetooth audio dongle (which is detected as a USB audio device in Linux) works much better than using the Bluetooth 4.0 usb dongle for audio purpose because you can use low latency aptx codex and Bluetooth 5 without messing with random drivers from some github repos

Would this give latency comparable to wired?

No but it's way better than the standard SBC codex. The latency is supposed to be ~32ms: https://soundsightheadphones.com/guides/bluetooth-5-0-codecs-and-other-bluetooth-formats/

I would like to connect Bluetooth headphones and a DualShock controller to my PC for gaming purposes. Cables are annoying

I'm pretty sure you can use aptx codecs using a Bluetooth 4.0 dongle and pipewire/bluez5. Just be aware when using them for gaming, if the game is cpu-bound and starved the system out of CPU time, the bluetooth audio might start to stutter. A Bluetooth audio dongle never stutter because they have their own independent Bluetooth stack, but they're about 10x more expensive than a Bluetooth 4.0 dongle (~$50) and can only be used for audio only.

This is super helpful, thanks!

Neat, didn't think of that!

The Asus BT500 dongle works quite well in my experience as long as you're running a kernel from the last 1-2 years, it's only BT 5.0 though.
