Detecting Wi-Fi networks with an M5Stack scanner with an LED indicator – part 2

You have investigated two Wi-Fi scanner designs using the M5Stack Core controller. The first Wi-Fi scanner design allowed you to manipulate the C++ code to change the text font size. The second Wi-Fi scanner design provided a quick method to assess your wireless home networks. Having gone through these two design approaches, you now have the knowledge and technical skills to enhance the Wi-Fi scanner. The enhancement will require adding an LED indicator. To make this physical visual feature improvement to the Wi-Fi scanner, a software modification is needed. The concept for the Wi-Fi scanner with an LED indicator is shown in Figure 8.22:

The diagram illustrates a home network in which the LED provides a visual indication of detecting wireless devices. The M5Stack Core Wi-Fi scanner that we investigated in the...
