Hi @lixy123

Currently, the WebSocketServer features of this library is not working due to similar issues in

1. No free space new client / Counting of clients wrong? #2
2. Major issue with WiFiNINA - Arduino IoT 33 #3

The timeline when to fix is not determined yet.

I'll post a warning in README about the WebSocketServer issues.

Hi @lixy123

Please try the new WebSockets2_Generic Library I believe there is no WebSocket Server issue as this WebSockets_Generic Library.

This is terminal debug output when running SAMDUE-Ethernet-Server on SAM DUE board with Ethernet W5100 shield using EthernetLarge library, and receiving WebSockets connection from an ESP8266 board.

Why do we need this WebSockets2_Generic library

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 WebSockets2_Generic library is based on and modified from Gil Maimon's ArduinoWebSockets Library to provide support to many more boards, such as 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, W5x00/ENC28J60/LAN8742A Ethernet, ESP8266/ESP32-AT modules/shields.

---

New in v1.0.1

1. Add support to SAM DUE boards.
2. Add support to Ethernet W5x00, using either Ethernet, EthernetLarge or Ethernet2 library.
3. Restructure code to provide flexibility to support many more WiFi/Ethernet modules/shields in the future. Please delete the *.cpp files, replaced by *.hpp files, in the src directory, if *.cpp files still exist after installing new version.

New in v1.0.0

1. Add support to nRF52 boards, such as AdaFruit Feather nRF52832, nRF52840 Express, BlueFruit Sense, Itsy-Bitsy nRF52840 Express, Metro nRF52840 Express, NINA_B302_ublox, NINA_B112_ublox, etc..
2. Add support to SAMD51 (Itsy-Bitsy M4, Metro M4, Grand Central M4, Feather M4 Express, etc.).
3. Add support to SAMD21 (ZERO, MKR, NANO_33_IOT, M0, M0 Pro, AdaFruit CIRCUITPLAYGROUND_EXPRESS, etc.).
4. Add Alexa / SINRIC examples and supports to those boards as well as ESP8266/ESP32

[khoih-prog]

The new WebSockets2_Generic v1.0.6 has been released with these new features to fix the blocking action of WebSockets Server that prevents the concurrent running of WebServer and WebSockets Server you experienced so far.

New in WebSockets2_Generic v1.0.6

1. Add non-blocking WebSockets Server feature to enable WS Server and WebServer running concurently. See Support as Http server and the Websockets server on Arduino DUE and Running Http and Websocket Servers concurrently. Thanks to bug report and persistence of Jake.
2. Add non-blocking WebSockets Server and WebServer examples.
3. Add Ethernet Library Patches
4. Add Arduino SAMD Packages_Patches to fix compiler errors when using Standard Template Library STL

Please try the example SAMDUE-Ethernet_AdvancedWebServer or similar to have feelings. Then modify it to fix your purpose.
