This app allows you to send custom commands via a TCP connection. You input the IP address and port number for the TCP connection you would like to create, and then you can customize the ten buttons to have ten saved commands. The “Any Command” text field can send any message that is typed into the text field. A carriage return and linefeed are appended to all messages. It was originally developed for the NCSU Embedded Systems course ECE 306, but it works for any TCP connection you would like to create!
