socketIo server on SAMD board (nano iot)?

[sdetweil]

I have an environment where multiple Arduino devices send status and a mobile app also collects status. 3-4 times a second.

socketIo would make this a lot easier. but, I need one board to be the server that every other thing connects to. it is also the wifi ap.

I see clients, but no servers for SAMD. all the messages are JSON text, so ws would be ok too, altho I like the path triggering in socketIo.

You can try WS Server for SAMD by using WebSockets2_Generic Library. You can also use much better ESP32 as WS Server using this WebSockets_Generic Library.

I don't know when the SIO Server will be implemented, for ESP32/ESP8266, etc. But I think you can use cheap Raspberry Pi Zero W, running Raspbian Linux and SIO server easily and reliably.

yes, pi02w.. was just thinking the same. my reason for Arduino is gone.
