ESP32 Libraries

arduino-esp32 includes libraries for Arduino compatibility along with some object wrappers around hardware specific devices. Examples are included in the examples folder under each library folder. The ESP32 includes additional examples which need no special drivers.

ArduinoOTA

Over The Air firmware update daemon. Use espota.py to upload to the device.

AsyncUDP

Asynchronous task driven UDP datagram client/server

BLE
