In this tutorial we will check how to obtain the number of stations connected to a soft AP hosted by the ESP32, running the Arduino core. We will also obtain their MAC addresses. The tests were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board.
The objective of this post is to explain how to get started using the WiFi functionalities of the ESP32, more precisely how to scan surrounding WiFi networks and how to connect to a specific WiFi network. All the tests performed here were made on a DFRobot’s ESP-WROOM-32 module, integrated in a ESP32 FireBeetle board.
