arduinoWebSockets

WebSocket Server and Client for Arduino

a WebSocket Server and Client for Arduino based on RFC6455.

Supported features of RFC6455

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

Limitations

• 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)
• continuation frame reassembly need to be handled in the application code

Limitations for Async

• 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.

Supported Hardware

• ESP8266 Arduino for ESP8266
• ESP32 Arduino for ESP32
• ESP31B
• Raspberry Pi Pico W Arduino for Pico
• Particle with STM32 ARM Cortex M3
