What Is WIFI MODULE and How Does It Work?

2022-02-19/ By Admin

If you are interested in future technologies, two names that immediately come to mind are Artificial Intelligence (AI) and Internet of Things (IoT). AI is still in its early stages and much more to develop. But WIFI module is in Growth phase and a lot of IoT based products are already in the market.


In addition, there are many tools and hardware available in the market to make your product communicate with 'things' on the internet.

We have developed a lot of IoT Projects using SAILSKY XM285 LTE Module, which not only covers basic communication with other microcontrollers like Arduino, PIC, AVR, but WIFI module also includes many smart projects like Air Pollution Monitoring IOT based gas, Google Maps Vehicle Tracking, IOT based Auto Voice Control etc.

Components needed

  • Board STM32F103C8
  • XM285 Laptop Hotspot & Wi-Fi
  • ESP8266

Is SAILSKY XM285 LTE is a module or a microcontroller?

Most people call the SAILSKY XM285 LTE a module, but it is actually a microcontroller. SAILSKY XM285 is the name of the microcontroller developed by SAILSKY Systems, a shanghai company. This WIFI module is capable of performing WIFI related operations hence it is widely used as a module.

The SAILSKY XM285 LTE Module uses serial communication to interact with the microcontroller. So here TX & RX of SAILSKY XM285 connect to serial2 port (PA2 & PA3) of STM32 board.

Explanation of Code & Working Principle

The job of connecting SAILSKY XM285 LTE Module with STM32 is very simple. You can find the full operation in the video given at the end of this tutorial along with the code.

We use Arduino IDE to write and upload code to STM32

First, we need to make the circuit connections in WIFI module. After uploading the code, open Serial Monitor to monitor the progress. You will see the IP address on the Serial Monitor, copy the IP address from the Serial Monitor and paste it in your browser and click to see our web page. Remember to connect the computer and the ESP8266 module on the same Wi-Fi network.
