wlan.connect(ssid, password)

print('Connecting to WiFi...', end='')
while not wlan.isconnected():
    print('.', end='')
    time.sleep(1)

print('\nConnected. IP:', wlan.ifconfig()[0])

app = Microdot()

@app.route('/')

    return 'Hello, world!'

async def main():
    # start the server in a background task
    server = asyncio.create_task(app.start_server())

    # ... do other asynchronous work here ...

    # cleanup before ending the application
    await server
