WebSocket Server and Client for Arduino

a WebSocket Server and Client for Arduino based on RFC6455.

max input length is limited to the ram size and the WEBSOCKETS_MAX_DATA_SIZE define
max output length has no limit (the hardware is the limit)
Client send big frames with mask 0x00000000 (on AVR all frames)

Functions called from within the context of the websocket event might not honor yield() and/or delay(). See this issue for more info and a potential workaround.
wss / SSL is not possible.

version 2.0 and up is not compatible with AVR/ATmega, check ATmega branch.

Arduino for AVR not supports std namespace of c++.

supported for:

wss client on the ESP8266
wss / SSL is not natively supported in WebSocketsServer however it is possible to achieve secure websockets by running the device behind an SSL proxy. See Nginx for a sample Nginx server configuration file to enable this.

This libary can run in Async TCP mode on the ESP.

The mode can be aktivated in the WebSockets.h (see WEBSOCKETS_NETWORK_TYPE define).

ESPAsyncTCP libary is required.
