how to invoke pymata_aio socket for web control? about pymata-aio

[MrYsLab]

Hi Tony,
Do you have a Firmata sketch loaded on your Arduino? If not, you can find instructions here:

Also, is your Arduino plugged into your computer?

Thank you for your prompt reply. Firmata is loaded and the pymata-core example works fine. For some reason just the socket does not work. I am using a Mega board.

You are indeed correct. I tried on multiple platforms and they all fail the same way. The problem is that the websocket connection is being refused. I will need to investigate, what is going on with websockets. Hopefully I will have an answer soon.

How embarrassing. I forgot you need to start pymata_iot.py before bringing up the web pages. I just modified the wiki page to say that.
Please let me know if that solves the problem or not. Thanks.
