drone-kit Python is not connecting with Iris+
Question: I'm trying to build my first dronekit python program, and I'm doing some tests
with some examples but I couldn't connect to my UAV(Iris+). I plugged the usb
radio(3DR 915 MHz) and I put `vehicle = connect('/dev/ttyUSB0',
wait_ready=True)`. Actually I have no idea which string I should put in.
Thanks in advance guys, I need some help!

My code:

    
    
    print "Start simulator (SITL)"
    from dronekit_sitl import SITL
    sitl = SITL()
    sitl.download('copter', '3.3', verbose=True)
    sitl_args = ['-I0', '--model', 'quad', '--home=-35.363261,149.165230,584,353']
    sitl.launch(sitl_args, await_ready=True, restart=True)
    
    # Import DroneKit-Python
    from dronekit import connect, VehicleMode
    import time
    
    # Connect to the Vehicle.
    print "Connecting to vehicle on: '/dev/ttyUSB0'"
    vehicle = connect('/dev/ttyUSB0', wait_ready=True)
    
    # Get some vehicle attributes (state)
    print "Get some vehicle attribute values:"
    print " GPS: %s" % vehicle.gps_0
    print " Battery: %s" % vehicle.battery
    print " Last Heartbeat: %s" % vehicle.last_heartbeat
    print " Is Armable?: %s" % vehicle.is_armable
    print " System status: %s" % vehicle.system_status.state
    print " Mode: %s" % vehicle.mode.name    # settable
    
    # Close vehicle object before exiting script
    vehicle.close()
    
    # Shut down simulator
    sitl.stop()
    print("Completed")
    


Answer: Best place for getting dk support now is probably here:

In answer, I have not tried this on Linux. I suspect the connection string is
correct, but you may have to also set the baud rate using baud=57600
