CAT1 4g+ Ethernet development board 232 data is sent to the server through 4G module TCP

One 、 Test materials

①DTU Development board floor
②EC200T-CN Core module
③ST-LINK Emulator
④USB-232 Serial line
⑤5V-2A The power adapter
Two 、 Equipment wiring
2.1 place 4G card
take EC200S-CN The module core board starts from DTU Unplug the development board from the bottom plate , take 4G Insert the card inward at the notch . And then put it back on the table EC200S-CN Plug the module core board back DTU Development board floor .


2.2 Access the emulator
Access the emulator , For downloading programs .
Connect the simulator with DuPont line according to the following figure DTU Development board floor ,USB End access computer .

2.3 Access USB-232 Serial line
take USB-232 One end of the serial port cable is connected DTU Development board floor , Connect the other end to the computer .

2.4 Connect the power adapter
Connect one end of the power adapter DTU Development board floor , The other end is connected to the socket , After power on , Module lights up .

3、 ... and 、 Server startup Socket Debugging tools
3.1 Log in to the remote server
Search your computer for remote desktop connections .


3.2 open Socket Debugging tools
take Socket Debug tools and other files are hung to the server , open Socket Debugging tools .
take Socket The port number of the debugging tool is set to 9988（ Customize , There is no need for consistency ）.

Four 、 Program download
use Keil open programs .（ open Keil error , Official account of WeChat ： WeChat search nnhptch Or Nanning lakeside Technology ：Keil5 And chip package installation and Keil5 open Keil4 Project compilation error solution .）
open programs .

4.1 Configuration emulator
If you have configured , You can ignore this step .



Download will Cortex-M Target Driver Setup Medium reset and run On the hook , The path is shown in the figure .



4.2 Download program
Modify the program

After the modification is completed , Click recompile , download .

5、 ... and 、 See the effect
Open the computer device manager , Check the port , Then open the serial port tool , Open the serial port .
My computer → Right click → attribute → Device manager .

In developing tools ( The software is here ) Under the folder , open SSCOM3.2 Serial tools , See the effect .
Select the corresponding serial port number , As you can see from the picture above , We choose COM3, The baud rate is 115200, Then open the serial port .
Wait quietly for the connection , Enter server , notice Socket The debugging tool receives the data sent by the board .

232 The interface can send data to the server through our development board .

The server can also receive data through our board 232 The interface is displayed .
