@jakespeed1311

Thanks for your interest in the library.

Currently, SAM DUE is not supported. The WebSockets Server for many other boards is still not ready.

I'm in the process of porting the WebSockets library to Teensy, SAM DUE and STM32 running with W5x00, ENC28J60 and WiFiNINA, as well as make WebSockets Server working in those supported boards.

I think by next week, the new version will have those features added. But I can't promise everything is working as planned.

The library will hopefully provide the WebSocket Server feature for the SAM DUE, but you have to write the application to use the feature for your purpose (SD Card, HTTP Server, etc.).

Hello,
thank you for the good news, i hope for good things to come. The Http server and the SDCard output are already running. Now add the websock server, that would be really cool.
I keep my fingers crossed for a smooth adaptation to the new hardware
thanks
Jake

Some preliminary good news for SAM DUE, Teensy and STM32F

The WebSocket Server example has just been compiled smoothly, but it needs some important mods in the Arduino hardware package.

Still need some more tests to see if anything is broken. If you're willing to test, I'll post some fixes for you here early next week to have something to start working on.

Hi @jakespeed1311

Good news. Just posted the new release v2.2.2

New in v2.2.2

  1. Add support to Teensy boards, such as Teensy 4.1, 4.0. 3.6, 3.5, 3.2/3.1, 3.0, LC..
  2. Add support to STM32 (Nucleo-144, Nucleo-64, Nucleo-32, Discovery, STM32F1, STM32F3, STM32F4, STM32H7, STM32L0, etc.).
  3. Add support to SAM DUE
  4. Add WebSocketServer examples to those supported boards.

Remember to follows instructions in

Important Notes to add support to SAM DUE

The Generic_WebSocketServerAllFunctionsDemo_W5500 example will show you how to run both EthernetWebServer and WebSockets Server for Generic boards (including SAM DUE) with W5x00 Ethernet.

Please post your test results if OK.

Good luck,

from websockets_generic.

Hi @jakespeed1311

The WebSockets Server currently has severe bug, and currently is not working.

I think you got the similar issue as the other 2 issues

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

I'm working on that now. But the outcome and time frame to fix is not determined, and can be quite long. If you can find another quicker solution, I suggest you go with that.

Hi @jakespeed1311

Thanks for your help. The same issue also happens while using other Ethernet/WiFi such as WiFiNINA, etc.
I'm narrow it down to the same client number issue, but still haven't had a solution yet.
Any more help will be appreciated.

Hi @jakespeed1311

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

You can start from this modified sketch for SAM-DUE and WebSockets2_Generic Library.

You have to spend more time to improve it. Currently the modifications are just to show you how to make it working basically.

You have to run the posted sample code (with the IP address modified) successfully to be sure your board / settings are OK before changing the code gradually to fix your purpose.

If not OK, you have to fix your hardware / settings first.

Do you have to use

IPAddress serverIP(192, 168, 33, 85);

or it's better to use DHCP IP

 // start the ethernet connection and the server:
  // Use Static IP
  //Ethernet.begin(mac, serverIP);
  //Configure IP address via DHCP
  Ethernet.begin(mac);

I can't help any further

Probably it works because your clients are constantly querying the websocket and can do that ?

If you specify your problem early, it'll be helpful and save time

OK, if I understand correctly now, your problem is that

  1. the WebSocketServer is in blocking mode
  2. you don't have any WebSockets Client
  3. WS Server is blocked, waiting for Client before moving forward
  4. The HTTP WebServer can't continue.

If so, I think I can fix the problem by modifying the WebSockets2_Generic Library.

Please wait until I find out the fix and post the new release.

I'm moving the issue to the correct place of WebSockets2_Generic Library as Running Http and Websocket Servers concurrently

From now on, please post to the new place.

Hi @jakespeed1311

The new Version 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 to have feelings. Then modify it to fix your purpose.

Please be noted that your bug report and persistence, resulting in the new Version v1.0.6, has been noted in Contributions-and-Thanks

from websockets_generic.
