WiFi Car Remote App is developed for a toy car based on the ESP32 microcontroller module. ESP32 is a highly-integrated solution for WiFi and Bluetooth IoT applications. Currently, the app only supports WiFi connectivity. The controller kit can operate in access point mode or station mode. In station mode, the app and toy car both need to connect to and WiFi router whereas in access point mode the app can directly connect to esp32 WiFi. In both modes, the app communicates with the toy car over a UDP socket.
