Support 4 socket connections at the same time
It supports simultaneous connection with 4 sockets,each socket can be individually configured as TCP server,TCP client,UDP Master,UDP Slave,
TCP-ZSD,UDP-ZSD,to meet users`various applications.
TCP Server Mode
The serial server listens on the local port and waits for the client to connect. After the connection is successful, data can be transmitted in duplex mode.
TCP client mode
The serial server actively connects with the user's server, and data can be transmitted in duplex mode after successful connection.
UDP Master mode
The serial server sends UDP data to the configured remote IP and port and only receives the data from them.
UDP Slave mode
The serial server listens for UDP data locally, and sends and receives data
with the latest communication client.
TCP-ZSD UDP-ZSD mode
The TCP / UDP protocol encapsulated by MIND is compatible with all 2G / 3G / 4G DTU of Mind, and different devices can be mixed in the same data center.
Using SDK kit to build center quickly.
Support dynamic domain name resolution
Support dynamic domain name resolution,
you can connect to the server without a fixed IP.
