WebSockets_Generic

How To Install Using Arduino Library Manager


Why do we need this WebSockets_Generic

Many Web services require WebSockets library, which is so far written only for ESP8266/ESP32 boards. The ESP boards so far rely on the Markus Sattler's WebSockets Library to connect to Alexa via Sinric or SinricPro skills.

This Markus Sattler's WebSockets Library is a RFC6455-based WebSocket Server and Client for Arduino boards. It is based on and modified from Markus Sattler's WebSockets Library to provide support to many more boards, such as WT32_ETH01 (ESP32 + LAN8720),
Arduino SAMD21, Adafruit SAMD21/SAMD51, nRF52, STM32, Teensy, SAM DUE, etc.
and enable those boards to use WebSockets services, including voice-control Alexa along with Blynk. Those supported boards can also run WebSockets Server. The WebSockets can be used with ESP’s WiFi, WiFiNINA, WiFi101, W5x00, LAN8720 and ENC28J60 Ethernet


Major Release v2.8.0

1. Add support to WT32_ETH01 (ESP32 + LAN8720) boards
2. Add examples with new features

Supported features of RFC6455

- text frame
- binary frame
- connection close
- ping
- pong
- continuation frame

1. Example code ESP32_WebSocketClientSSL

2. This is the terminal output when running WT32_ETH01_WebSocketClientSocketIO example on WT32_ETH01:

Code: Select all
