What happened to BluetoothConnection, and how do I replicate functionallity with BluetoothClient?

Hi, this is probably an obvious mistake but I'm new to the MIT App Inventor ecosystem.

I'm trying to bring up a Bluetooth connection so I can talk to an Arduino via an HC-05/06. Looking at an example called Connect_STARTER which invokes an object called BluetoothConnection, which does lovely things like StartScanning for available connections, etc.:


This object is not available in the pallet of MIT Inventor I'm using. I don't see this functionality available from either the BluetoothClient or BluetoothServer objects. And I can't just copy the object from the example project into mine.

Can anyone offer some advice??? Is this a now deprecated function?

Doh! It looks like this is a BluetoothLE object, which the authors of Connect_STARTER just renamed to BluetoothConnection!

Thanks, all...
