Python: How to get connected bluetooth devices? (Linux)

I need all connected bluetooth devices to my computer. I found library, but i can't get connected devices

Simple inquiry example:

    import bluetooth

    nearby_devices = bluetooth.discover_devices(lookup_names=True)
    print("Found {} devices.".format(len(nearby_devices)))

    for addr, name in nearby_devices:
        print("  {} - {}".format(addr, name))

The snippet of code in the question is doing a scan for new devices rather than reporting on connected devices.

The PyBluez library is not under active development so I tend to avoid it.

BlueZ (the Bluetooth stack on Linux) offers a set of API's through D-Bus that are accessible with Python using D-Bus bindings. I prefer pydbus for most situations.

The BlueZ API is documented at:

https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc/org.bluez.Adapter.rst

https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc/org.bluez.Device.rst

As an example of how to implement this in Python3:

import pydbus

bus = pydbus.SystemBus()

adapter = bus.get('org.bluez', '/org/bluez/hci0')
mngr = bus.get('org.bluez', '/')

def list_connected_devices():
    mngd_objs = mngr.GetManagedObjects()
    for path in mngd_objs:
        con_state = mngd_objs[path].get('org.bluez.Device1', {}).get('Connected', False)
        if con_state:
            addr = mngd_objs[path].get('org.bluez.Device1', {}).get('Address')
            name = mngd_objs[path].get('org.bluez.Device1', {}).get('Name')
            print(f'Device {name} [{addr}] is connected')

if __name__ == '__main__':
    list_connected_devices()
