Until upgrading I was able to connect with Bluetooth and BLE devices on Parallels virtual machines by checking the "Apple Bluetooth USB Host controller" option in the Parallels tool. I can still check it, but for some reason I can no longer see to connect to any bluetooth or BLE devices.
Also, if you have any advise how to downgrade Parallels to a version prior to current I assume it can be of use.
I run Parallels over Mac OS 10.9.5
Thanks, Asaf
Turning to Parallels, alas yields no reply. So I turned to a friend. Here's what worked for me to enable bluetooth and BLE connectivity in a Parallels virtual machine:
2. Turn on Apple Bluetooth USB Host Controller for list of devices
And that's it, basically. You can restart the virtual machine to see the bluetooth icon on the top status bar of your virtual machine but basically - problem solved. Hope this helps someone.
