# 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
  Bluetooth Low Energy v4.2 client/server framework

### BluetoothSerial
  Serial to Bluetooth redirection server\
  Note: This library depends on Bluetooth Classic which is only available for ESP32\
  (Bluetoothserial is **not available** for ESP32-S2, ESP32-C3, ESP32-S3).

### DNSServer
  A basic UDP DNS daemon (includes captive portal demo)

### EEPROM
  Arduino compatibility for EEPROM (using flash)
