How to do it...

The steps for this recipe are as follows:

1. On the device side, import the necessary libraries:

import asyncio
from six.moves import input
from azure.iot.device.aio import IoTHubDeviceClient

2. Create a main() function and connect to the device:

async def main():
    device_client = \
    IoTHubDeviceClient.create_from_connection_string("Connection
                                                     String")
 
    await device_client.connect()

3. Create a twin listener:

    def quit_listener():
        while True:
        selection = input("Press Q to quit\n")
        if selection == "Q" or selection == "q":
            print("Quitting...")
            break

4. Create a listen task:

    asyncio.create_task(twin_patch_listener(device_client))

5. Listen for a quit signal:

    loop = asyncio.get_running_loop()
    user_finished = loop.run_in_executor(None, quit_listener)

6. Wait for the user finish signal and disconnect:

    await user_finished...
