Description of Change Fixes IPAddress INADDR_NONE declaration when using Arduino WiFi or ETH. This symbol was defined as 0xffffffff by lwip /inet.h, making it impossible to use INADDR_NONE correctly. This PR only works when <wifi-provisioning/wifi_config.h> has a modification to include <lwip/ip4_addr.h> instead of <lwip/inet.h>. This will be done directly to the sdk folder in the github structure and it has been fixed in IDF by a separated Merge Request. This will be reflected in the future, for good. Tests scenarios This PR was tested with all Arduino WiFi examples, including AsyncUDP. Also with ETH examples. It was also tested for #6610 test cases. Testing done for ESP32, ESP32-S2, ESP32-C3 and ESP32-S3. Related links fixes #6610 fixes #6247 fixes #4732
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)
