I'm working with PX4 firmware (the last one) and JmavSim as simulator.
I've enabled the UDP ports

INFO [mavlink] mode: Normal, data rate: 4000000 B/s on udp port 14570 remote port 14550
INFO [mavlink] mode: Onboard, data rate: 4000000 B/s on udp port 14580 remote port 14540

I've found an interesting nodejs project here :
https://github.com/kvenux/nodegcs

that uses this library to decode mavlink messages

https://github.com/omcaree/node-mavlink#readme

and I'm trying to rewrite it using dgram library instead of "net" in order to use UDP connection.

And it seems to works pretty well as a listerner of data.

I create the socket (here connection_port :14570 ):

mav_port_receive = dgram.createSocket("udp4")
mav_port_receive.bind( connection_port,connection_path);

mav_parser.on( 'ready', function () 
 mav_port_receive.on("message", (msg, rinfo) => 
 if(msg[0]!= 0 && msg[1]!= 7)
 var radio_status = 
 rssi: parseInt(msg[2]),
 ;
 
 mav_parser.parse(msg);
 );
..

But when I try to send commands using this code
-> here PORT : 14550

mav_parser.createMessage("COMMAND_LONG", 
"param1": param1,
"param2": param2,
"param3": param3,
"param4": param4,
"param5": param5,
"param6": param6,
"param7": param7,
"command": command,
"target_system":1,
"target_component": 1,
"confirmation": confirmation
,
function (message) 
 mav_port_receive.send(message.buffer, 0, message.buffer.length, PORT, HOST, function(err, bytes) 
 if (err) 
 LOG(err)
 

 );

 return;
);
}

It return me an error in the px4 console

"WARN [mavlink] ignoring CMD with same SYS/COMP (1/1)"

I've tried to change the way it creates buffer, but the problerm persist.
I've tried to change the ""target_system":1, "target_component": 1" using different numeric values but it does nothing ( even no message errors)

I've tried to use a different udp socket ( a new one ) ... same problem

Even with basic command as "arm" it doesn't work and returns the same error.

function port_send_message(message) 


 mav_port_receive.send(message.buffer, 0, message.buffer.length, PORT, HOST, function(err, bytes) 
 if (err) throw err;

 // mav_port_send.close();
 );

 return;

Can u help me to fix ?
