I just installed the adapter and it seems to be working properly with my Bluetooth 2.0 device, but I’m unable to get my other Bluetooth 4.2 device to properly work.
I’m able to connect to the device, and it shows up under the “Playback” tab of audio devices, but doesn’t let me set as default and is grayed out saying “Disconnected” despite it showing up as connected in the Bluetooth settings.
After looking further into this, I realized that because your USB adapter is 4.0, it may have trouble connecting to 4.2 devices. However, I found this support forum saying that there possibly is a workaround.
I followed all the steps, and here’s a link to the file it created (sorry, don’t see an option to upload it here):
Please know if there’s anything we can do about this, thanks!
