+====== STM_IoT_AT: Programming of the WiFi interface with AT commands =====
 The STM32WB55 SoC doesn't have a WiFi network controller so our STM laboratory stands have the WiFi module based on ESP32-C3 SoC connected by serial port and controlled with AT commands. In this scenario, you will learn how to use these commands.

 You should be able to see the "AT" displayed on the upper line of the LCD, and "OK" on the lower line of the LCD. If any error in the communication with the ESP32-C3 module occurs the second line shows "ERROR".
+<note info>
+Because LCD can't properly display some non-visible characters the presented code sometimes shows additional, non-letter characters. It is out of the scope of this scenario to filter these characters out. We leave the task of making visual improvements to your invention.

 ===== FAQ =====
-**Do I need to write the program for the WiFi module?** No you don't have to. The ESP32-C3 module is flashed with the firmware from Espressif which implements all functionality for WiFi and MQTT. There are other modules which offer similar functionality.

-**Can I use a similar WiFi module in my own IoT projects?** Certainly! The universal serial port connects the module so the module can be used with almost every microcontroller as the WiFi network controller.

-**Are AT commands the same for all modules available?** The basing AT command set is in general the same, but advanced functionality as WiFi, MQTT and others can use different syntax for modules coming from different producers. Always refer to the original documentation for details.
