Detecting Wi-Fi networks with an M5Stack scanner – part 1

You have seen that the M5Stack Core has a Wi-Fi subsystem consisting of a baseband and MAC electronic circuits. To aid these hardware elements, the software allows the configuration of these circuits with the ESP32 microcontroller core subsystem. The M5Stack Core will allow us to assess a home Wi-Fi network displayed on a 2-inch TFT LCD. The application detection code will help the M5Stack Core cohesively stitch the Wi-Fi circuits to the ESP32 core subsystem. This is all achieved using the Wi-Fi scan code found within the Arduino IDE examples. You will use the M5Stack Core example WiFiScan code to assess and display the wireless networks within your home. To access the C++code, select File | Examples | M5Stack | Advanced | WiFi | WiFiScan with your mouse. Figure 8.15 shows the selection sequence for obtaining the WiFiScan code:
