Newbie Question. Trying to get Parameter List

[GoogleCodeExporter]

Hi Guillaume,

This is the first time I'm trying to interface into the Mavlink libraries and 
I'm running into some road blocks.  The first thing I want to try to do is read 
the parameter list.  Below is a code snippet.  I am always getting null 
messages when I try to getNextMessage.  Any thoughts?

            //open the port
            CommPort cPort = CommPortIdentifier.getPortIdentifier("COM4")
                    .open("testApp", 5000);
            DataInputStream dis = new DataInputStream(cPort.getInputStream());

            MAVLinkReader reader = new MAVLinkReader(dis, IMAVLinkMessage.MAVPROT_PACKET_START_V10);
            MAVLinkMessage msg;

            requestParameterList(cPort);
            while (true) {
                msg = getNextMessage(reader);
                if (msg != null) {
                    // Do your stuff

                }
            }

private static void requestParameterList(CommPort cPort) throws IOException {
        msg_param_request_list pr = new msg_param_request_list(1, 1);
        byte[] result = pr.encode();
        DataOutputStream dos = new DataOutputStream(cPort.getOutputStream());

        dos.write(result);
    }

Hello,

the project has moved here :
https://github.com/ghelle/MAVLinkJava 

Have a look to TestMavlinkReader.java in org.mavlink.library to read Mavlink 
messages.
