Tp-Link UB500 reports wrong Bluetooth version
The UB500 Bluetooth dongle from Tp-Link reports Bluetooth 5.1, but it is capable of at least Bluetooth 5.3. I verified with both
btmgmt and hciconfig.
I've managed to make it use a more up-to-date firmware in Bazzite by putting the firmware rtl8761bu_fw.bin in /usr/local/lib/firmware and adding the kargs rpm-ostree kargs --append-if-missing="firmware_class.path=/usr/local/lib/firmware".
I downloaded the driver directly from Tp-Link's site for this. The BT dongle I bought is version 2. There's at least 3 versions, and I even managed to use the firmware from v3 and it reports Bluetooth 5.4, but I don't really know if it is actually compatible with it since I can't find if a Bluetooth 5.3 device can be updated to 5.4. I also did this in Windows and it worked too so there seems to at least not be an apparent problem.
Is this the correct place to report this or should I report it somewhere else?7 replies
