Connect to Bluetooth device via terminal

I am struggling to find some (elegant) way to connect my Mac to a (previously paired) Bluetooth device via terminal.

There is a solution using Applescript simulating mouse clicks, but it has some major issues:

• Bluetooth menu needs to be visible in the Menu bar
• Terminal needs access to the Accessibility Controls
• Does not work reliably
• It is slow as hell
• When you use the mouse while the script is running, it fails.

So, this is more or less a no-go..

I don't need to switch Bluetooth on and off in general, I don't need any pairing mechanism, I just need some way to trigger the connection to known devices via terminal.

My use case is a Bluetooth Sound Module - for example I called it "NoiseBox". What I want is this:

./magic-script.sh connect NoiseBox

or

./magic-script.sh disconnect NoiseBox 

Can you help me?

PS: Is it possible to write some small Application in Swift or ObjC which does this?

Solution 1:

As there are some upvotes and many views, I will answer my own question there:

Yes, it is possible to write some small application in Swift or ObjC which does this. And some people did that already:

• BluetoothConnector
• blueutil

BluetoothConnector is written in Swift, which does (currently) only support connecting and disconnecting (It seems to be pretty new, so more features may follow some day).

blueutil is written in Objective-C. In addition to (dis-)connecting it can also toggle power, discoverability, show if you are already connected, etc.

I tried both, and both worked well, currently I'll stick with blueutil - it has more features, which come in handy in shell scripts.
