I'm sending messages trough a socket connection to a device. The device
sends a message on which i need to respond.
This is my code for opening a socket connection:
var lPORT = 4102;
// Create a server instance, and chain the listen function to it
net.createServer(function(sock) {
// We have a connection - a socket object is assigned to the
connection automatically
console.log('TCP LISTENER hearing on: ' + sock.remoteAddress +':'+
sock.remotePort);
// Event handler: incoming data
sock.on('data', function(data) {
sock.allowHalfOpen = true;
sock.pipe(sock);
var sockwrite = sock.write(data+'\r\n');
if (sockwrite == true) {
console.log(''+data);
}
// Write incoming messages to logfile.
var log = fs.createWriteStream('pin.log', {'flags': 'a'});
log.write(data+'\n\r\n\r');
// Push incoming messages to client
io.of('/process').emit( 'broadcast_msg', ''+data);
});
// Event handler: close connection
sock.on('close', function(data) {
console.log('[LISTENER] Connection paused.');
});
}).listen(lPORT);
Beneath is the code for connecting to that socket connection and sending
the data. But that data is not physicly send to the socket, i checked this
with wireshark. The message send from this code is not send.
var returnsock = net.createConnection(4102, function() {
returnsock.write(msg);
});
The point is, that the data send from "returnsock.write(msg);" **does**
come trough in the code above, i can see that when i view my console.log.
So, "var sockwrite = sock.write(data+'\r\n');" comes back with "true".
My question is: Why is the data that is send from "returnsock.write(msg)"
come tru to the server, but is not send inside the socket with "var
sockwrite = sock.write(data+'\r\n')"?
Thanks in advance!
