MIT app inventor Android App, connected with board by TCP/IP

I like support to design an Android App using MIT App Inventor, the App should manage a slave controller connected by an interface to Android Tablet via TCP/IP and Supports 24 electronic signals. Project MUST to be developed using [login to view URL] Specifically, I like to make a program using Blocks editor (by myself), but I need the freeleancer provides to me: 1. Provide the extension (delivering extension code) to allows the communication between App Inventor and the Slave Controller, allowing to send the output signal in each channel. 2. Provide a blocks software (delivering blocks code), which request the number of the channel, and, according to it, send the output signal to the slave controller. 3. After the success of this sprint, I'll request other developments.
