I am using a plugable Bluetooth USB Adapter. More information is available at: plugable.com/usb-bt4le
I can connect and recognize my iPhone using the Bluetooth adapter.
I'm not sure how to check versions of CLI but I just downloaded and installed it. It should be the latest.
I have the build tools installed. Got these messages from Command Prompt:
Waiting for installers... \Successfully installed Python 2.7
Waiting for installers... |Successfully installed Visual Studio Build Tools.
ERROR: No compatible USB Bluetooth 4.0 device found!
Any other suggestions?
