1.FUNCTION DESCRIPTION

The products to which this document applies have the following characteristics.

➢Connect the device to a PC or other server by establishing TCP/UDP or Telnet to support up

to 3 socket communications.

➢One or Two independent serial ports work.

➢Support IOTService to remotely modify module working parameters.

1.1. Basic Network Protocol

The products uses IP address for network communication. Transmit by TCP, the data can be

ensured without loss or duplication, and reach the communication destination address accurately. And

transmit by UDP, the data can be transmitted to the destination address quickly and efficiently.

Figure 1. Network Application

1.2. Working Mode

1.2.1. Transparent Throughput Mode

The device supports a serial interface for transparent throughput mode. In this mode, the user

only needs to set some necessary parameters (network communication parameters). After power-on,

the device can automatically connect to the default network and server. Use the IOTService software

to set communication parameters.

Figure 2. Transparent Throughput Mode

Under this mode, the user's serial device can send data to the specified server on the network

through this module. The module can also receive data from the server and forward the information to

the serial device.

The user does not need to pay attention to the data conversion process between the serial port

data and the network data packet, and the data transparent communication between the serial port

device and the network server can be realized by simple parameter setting.

This module supports 3 socket connections, which are SOCKA, SOCKB, and SOCKC, which are

independent of each other. Each socket supports TCP client or UDP client.

For TCP connections, users can set the communication method for long or short connections. A

short connection means that the connection is initiated when the serial port data is received, and the

connection is automatically disconnected after a certain period of time. The server resources are

greatly saved, but the connection process takes a certain amount of time, causing data transmission

delay, and the server cannot actively send data to the device. Long connection means that data can

be sent and received at any time, but it takes up server connection resources.

The data transmission case is as follows:

1、After setting the following communication parameters command, the device will restart,

2、Waiting for the network LED shows register to the network. After sending the UART data, the

server replies with the IP address, port number and received data, as shown below:

Figure 4. Transparent Data Example

1.2.2. SMS Throughput Mode

In this mode, the UART data can be sent to and receive from short message.

Figure 5. Transparent Transmission Mode Registration Packet Function Transmission

1.2.3. SOCKA HTTP Mode

SOCKA channel support HTTP protocol. Under this mode, the user's terminal device can send

request data to the specified HTTP server through this module. The module will receive the data from

the HTTP server, parses the data and sends the results to the serial device. The user does not need

to pay attention to the data conversion process between the serial port data and the network data
