Creating UPD TCP Connection

[Eugene_200]

Hi all,

I am looking for basic code example of how to initiate a
simple TCP/UDP connection from the mobile phone to a regular PC using a specific ip and port numbers, so that i will be able to transfer any data between the mobile phone and the PC,
(I already know, i need to create socket but i just don't know how to do all that stuff on the mobile phone)

regards,
Eugene

for TCP u can use something like this in client mobile:

// create a TCP socketconnection to the server

SocketConnection obSocketConnection = (SocketConnection)Connector.open(socket://"+URLserver+":"+serverPort);
// Disable Nagle algorithm: 

obSocketConnection.setSocketOption(SocketConnection.DELAY, 0);
// open the input and output streams

InputStream in = obSocketConnection.openInputStream();
OutputStream out = obSocketConnection.openOutputStream();

and something like this in server :

ServerSocket obServerSocket = new ServerSocket(iTCPport);
while(true){
//create a TCP Socket Connection to Client
Socket obClientSocket = obServerSocket.accept();
if (!useNagle)
obClientSocket.setTcpNoDelay(true);

for UDP u can use something like this in client mobile:

DatagramConnection  obDatagramConnection = (DatagramConnection) Connector.open(sURLserver);

Datagram obReceiveDatagram = obDatagramConnection.newDatagram(obDatagramConnection.getMaximumLength());
obDatagramConnection.receive(obReceiveDatagram);

Datagram obSendingDatagram = obDatagramConnection.newDatagram(sendData,sendData.length);                           
obDatagramConnection.send(obSendingDatagram);

in server :

DatagramSocket obServerDatagram = new DatagramSocket(iUDPport);
DatagramPacket in = new DatagramPacket(byteReceiveBuffer, byteReceiveBuffer.length);
obServerDatagram.receive(in);

hope it can help
