TCP / UDP - Server / Client A simple Server - Client app which can be used for testing purposes. A server can be started which listens for incoming client connections. The server's IP address is the device's IP address. A port number between 0 and 65535 can be freely selected. The server is not limited by 'one' client connection, several clients can connect to the server. There are 2 Log windows where one is the event log and text sending/receiving and the other window shows the Hex values for sending and receiving. The server can respond to received data from a Client: - By sending received data back to the Client (echo) - Send an entered text back to the Client - By looking up a table you have defined and finding a match in this and then sending the associated data back to the Client The app is primarily developed for use on an iPad, but it can easily be used on an iPhone, although the screen is a bit small for this.
