• Added support for connecting to Twitch Chat
• Added basic example for twitch chat
• Re-organized examples
• Updated version number to 0.2.0

Thanks for the library!

I will like to enterró IRC channel with my register user into a channel. Then I will monitorized the messages and when a messages be the same a text, for example "help" then a led will turn ON and I will enter.

In the same way I will like to send some predefined text with buttons.

What do you think about this?

The third field of keywords.txt is used to provide Arduino Language/Libraries Reference links, which are accessed from the Arduino IDE by highlighting the keyword and then selecting "Find in Reference" from the Help or right click menu. Adding values to this field that do not match any existing reference pages results in a "Could not open the URL" error.

I know this is setup for an ESP8266, however I can't seem to find anywhere else to help with the error message I am getting:

Description

Basically, this all works without issue on an ESP8266, but using the 32 I am able to connect to the twitch chat then my wifi disconnects and I get:

[I][WiFiClient.cpp:548] connected(): Unexpected: RES: 0, ERR: 119

Troubleshooting

Removing all the twitch code so it is just simple code to connect to the internet with wifi works without issue. I have serial confirm the IP address every 5 minutes and can confirm it is connected to my router. Could be related to the wifi.h and IRCClient.h being used together?

Board

I'm using a Wemos Lolin32 Lite , DOIT ESP32 Dev Kit V1 generic ESP32 etc. Arduino 1.8.12

Lastly

This code and the things you provide have been so helpful in learning about Arduino and have helped me make a bunch of things I would never have dreamed of without the ideas and functionality of code like this !!! you ROCK!
