MATLAB installed on macOS 12 (Monterey) does not detect nearby Bluetooth Low Energy devices when you run blelist without arguments or with any arguments other than the "Services" name-value pair. The command returns an empty table. Connecting to a Bluetooth Low Energy device by using the ble object also fails because the device is not discoverable using blelist.

Update the macOS to macOS Monterey 12.3 or a later version, and then start MATLAB. You can then run blelist with or without arguments to scan for nearby Bluetooth Low Energy devices.
