receiving and sending mavlink messages using pymavlink library
I have created a proxy between QGC(Ground Control Station) and vehicle in Python. Here is the code:
gcs_conn = mavutil.mavlink_connection('tcpin:localhost:15795')
gcs_conn.wait_heartbeat()
print("Heartbeat from system (system %u component %u)" %(gcs_conn.target_system, gcs_conn.target_system))
vehicle = mavutil.mavlink_connection('tcp:localhost:5760')
vehicle.wait_heartbeat() # recieving heartbeat from the vehicle
print("Heartbeat from system (system %u component %u)" %(vehicle.target_system, vehicle.target_system))
while True:
gcs_msg = gcs_conn.recv_match()
if gcs_msg == None:
pass
else:
vehicle.mav.send(gcs_msg)
print(gcs_msg)
vcl_msg = vehicle.recv_match()
if vcl_msg == None:
pass
else:
gcs_conn.mav.send(vcl_msg)
print(vcl_msg)
I need to receive the messages from the QGC and then forward them to the vehicle and also receive the messages from the vehicle and forward them to the QGC.
When I run the code I get this error.
is there any one who can help me?

If you print your message before sending you'll notice it always fails when you try to send a BAD_DATA message type.
So this should fix it (same for vcl_msg):
if gcs_msg and gcs_msg.get_type() != 'BAD_DATA':
vehicle.mav.send(gcs_msg)
PD: I noticed that you don't specify tcp as input or output, it defaults to input. Than means both connections are inputs. I recommend setting up the GCS connection as output:
gcs_conn = mavutil.mavlink_connection('tcp:localhost:15795', input=False)
