Introduction:

A few weeks ago, I wrote a posting about WizFi250-CSI as below.

https://www.instructables.com/id/WizFi250-CSIC-Script-Interpreter-for-rapid-prototy/

And now, I will demonstrate a serial-to-wifi application using WizFi250-CSI.

With WizFi250-CSI, I finished the serial-to-wifi application. (Writing and testing).

Step 1: Description of WizFi250-CSI.h

You can any script with this “WizFi250-CSI.h” file.

This header file includes all API function which you can use for a script file.

For all “WizFi250-CSI.h”, you can refer to the below link.

Step 2: Write “C Script File” for Serial-To-WiFi

Please refer to the below script file.

Or you can refer the below link. http://ilikethisplus.tistory.com/38

Step 3: Upload “C Script File” for Serial-To-WiFi

At first, you should upload(or write) script file as the attached picture.

Step 4: Run “C Script File”

Now, if you reset the WizFi250-CSI, Serial-To-WiFi application will run as attached picture.Data-communication worked well in both Serial-to-WiFi and WiFi-to-Serial.

Step 5: Conclusion

Benefit of Serial-To-WiFi using WizFi250-CSI

  • The user can select TCP/UDP and Server/Client in source code level.
  • It’s very similar standard C.
  • User can define LED indications(GPIO or ADC)
  • The user doesn’t need serial-command(AT Command).
  • The user can implement data-packing of network-packet in socket-API.
  • Multi sockets are available
  • The user doesn’t need any tool or web server for configuration.
