Command Control Device SDmay11-02

This project involves developing a short-range wireless control device utilizing Bluetooth technology. The primary goal is to ensure that the transmitter (Tx) communicates effectively with the receiver (Rx) to execute specific commands programmed via a dongle. The system consists of four main components—a Transmitter, Receiver, Programming Dongle, and a GUI for managing programming tasks. Through extensive testing, including unit tests and communication link evaluations, the aim is to establish reliable operation before the project's completion on April 25.
