Here to introduce Android network communication
We know that Java provides the socket to complete the communication between the two PC computers. TCPServer needs the client and server, the server uses Socketserver and the socket completes, the client uses the socket to complete ... We are all familiar
Task
After completing the socket client's communication to the server, let me do two-way communication, and then let me use the app to control the height and gpio of the mouth. Efforts for three days, from the socket learning to multithreading learning, step-by-Step completion of the task, Test the flow of data from app to server on the small board. Record it before work. Train of thought

Signal communicationThe signaling (signal) mechanism is the oldest inter-process communication mechanism in UNIX systems, and there are many conditions that can produce a signal:1 . When the user presses certain keys, the signal is generated.2, the hardware abnormal generation signal: Divisor is zero, invalid storage access and so on. These signals are usually detected by hardware, notified to the kernel, and then the kernel generates an appropriate s
