Success (I think)!
As noted above, I have been searching for a reliable Bluetooth dongle for my desktop PC. I think I finally found it! And very cheaply, from AliBaba!
Details: UGREEN Bluetooth 5.3 Adapter, model CM591, A2DP / HSP / AVRCP / HID / PAN / GAV / US $7.45 only! Alibaba store link1.
This dongle has the following profiles:
A2DP / HSP / AVRCP / HID / PAN / GAVDP / DID / IOPT. As far as I can see, the GAVDP is the important profile that potentially allows broadcast streams in theatres, but I am unable to test if that works yet. If you want to get down and dirty with BT Profiles, see this link6
Like any consultant, I’m only one page ahead in the manual, but if anyone wants help, just yell.
I’m just delighted to have found something that actually works!
