I am trying to find the UUIDs of all connected bluetooth devices on MacOS Big Sur 11.6.2. I have the MAC addresses of all connected devices (obtained running: system_profiler SPBluetoothDataType) but not the UUIDs. I need the UUIDs because I would ultimately like to connect to specific devices programmatically using the bleak library in python3 which requires a UUID when run on MacOS.

I tried using this answer:

$ xcrun xctrace list devices
xcrun: error: unable to find utility "xtrace", not a developer tool or in PATH`

I do have XCode CLT installed (and just reinstalled it today to attempt a fix):

$ xcode-select -p
/Library/Developer/CommandLineTools

but it does not have the xctrace utility:

$ pwd
/Library/Developer/CommandLineTools/usr/bin
$ ls -al

I have also used the bleak library example to scan for all devices in range:

import asyncio
from bleak import BleakScanner

async def main():
    devices = await BleakScanner.discover()
    for d in devices:
        print(d)

asyncio.run(main())

but the devices to which I would like to connect do not have any identifying names / vendors / models:

One of these is the device to which I would like to connect programmatically using the UUID that corresponds to the MAC address that I already know from using the (Option key + Bluetooth) menu shortcut.

I would like to avoid downloading and installing the full XCode package if at all possible. Thanks for your suggestions.
