Here is an example that should work. I think your code above works but note that \x0D and \r are identical and you are sending 2 carriage returns with each command that does nothing except to cause extra processing on the receiver's end.

Put all this code into the Activity Script.


System.setDebugMask(9);

var socket;
var buffer = "";
var CR = "\r";


function onSocketConnect() {
// once connection is established, you can write anything
// write is not done here as we want to send commands based on button presses.
// sendCommand("!1MVLUP");
}

function onSocketData() {
var temp,first;
buffer+=socket.read();
// here, you have to use substring, split, or other methods to get actual messages.
// assuming that each response is delineated by a carriage return \r or \x0d, you can do the following:
first = buffer.indexOf(CR);
while (first >= 0) {
// do something with the data - extract first message up to but on including CR.
temp = buffer.substring(0, first);
buffer = buffer.substring(first + 1);
notifyMessageReceived(temp);
// find next CR.
first = buffer.indexOf(CR);
}
}

function onSocketIOError(e)
{
System.print("sock IO Error error:" + e);
}

function notifyMessageReceived(message) {
System.print("Received:");
// message will not have the terminating \r as it was stripped of as the message delimiter.
System.print(message);
}


function closeSocket() {
if (socket) {
if (socket.connected) socket.close;
socket = null;
}
}

function resetSocket() {
// if currently connected, clean things up.
closeSocket();
// create asynchronous socket.
socket = new TCPSocket(false);
// reset buffer clearing any data from previous socket.
buffer = "";

// assign callbacks for connect, data received, and ioError.
socket.onConnect = onSocketConnect;
socket.onData = onSocketData;
socket.onIOError = onSocketIOError;
}

function sendCommand(command) {
if (socket) socket.write(command + CR);
}

// create a new socket and connect
resetSocket();
// request connect to IP, port with a timeout
socket.connect("192.168.1.6",4999,10000);


Put this code into a button you create on a page in the same activity.

sendCommand("!1MVLUP");


On the same page, create a panel with ProntoScript Name of "_PS_DEBUG_" so you can see the output. See section 14.1 of the ProntoScript Dev Guide 1.4.3 from here [Link: files.remotecentral.com]
