In the past two days, the communication between PC and Android mobile phones is limited to the level. There are two methods available: socket based on data packets and Bluetooth. Although it looks simple, it has been adjusted for more than two days. I tested the socket. The latency in the indoor WIFI environment is about 0.1 s. The latency in 3G networks is as high as 3 s, and the port seems to be disconnec
