I would like to buy a cheap Bluetooth receiver/transmitter for my desktop computer running Fedora 32. I have searched eBay for that, but meanwhile learned that most of them do not work on Linux. So, could you please advise me on that?
Where did you see that most don't work? I think it's the opposite. As far as I know, they all work. It's USB wifi devices that you're more likely to have trouble with (at least 5GHz ones). I recently needed a bluetooth dongle for BLE and picked one of the cheaper ones I could find and it just worked.
Thanks, Samuel and George. I found issues of compatibility with Linux at:

Meanwhile, I bought the following Bluetooth dongle, which was very cheap and therefore the risk is low:
Well, I was like Samuel and thought that all BT dongles work fine under Linux.
However, I just bought one to replace a failed device. It is a newer model which is marked CSR 5 in support of BT version 5. It fails to be recognized by bluez as adapter.
btmon shows...
HCI Event: Command Complete (0x0e) plen 6 #62 [hci0] 12.841706
Delete Stored Link Key (0x03|0x0012) ncmd 1 Status: Unsupported Feature or Parameter Value (0x11) Num keys: 0
So, I would stay away from Version 5 products for the time being.
Side note: The bluez maintainers didn't respond to my query about support for this adapter. :-(
