The Android mobile terminal App applies the socket technology to the communication with the server. The server program sends commands to the ZigBee coordinator by USB serial communication, which has solved the fusion problem between TCP/IP protocol and ZigBee protocol stack. The ZigBee coordinator analyzes the commands, and transmits the corresponding control signal in the form of broadcasting to all ZigBee terminal nodes.The terminal nodes drive the HV9910B PWM dimming circuit, and implement a variety of LED lighting effects according to the control signal received. Experiments show that the system has good practicability, scalable and robustness.
