Using ESP8266 with an Arduino about pubsubclient

[knolleary]

Good question @ymaglaras

@tomn46037 could you give some pointers on what lib you used on the esp8266? I can get that added to the docs.

I used the latest version of the Arduino IDE (1.6.5) and I installed the ESP8266 toolchain with the Board manager (Tools->Boards->Boards Manager) then search for ESP8266. Mine shows that I have "ESP8266 Community version 1.6.5-947-g39819f0".

With this library, the ESP8266 Wifi uses the "client" interface the same as the ethernet shield.

I created a new repo with my test code. It should compile and connect to the MQTT server. It should subscribe and you should be able to publish to it. Again, this is very rough.. but it does compile and will connect to the MQTT server and publish/subscribe and print incoming messages. The repo is at

Thanks @tomn46037

@ymaglaras : does that answer you questions?

Closing as the info from Tom answers the questions. At some point, I'll add as ESP8266 example to the library - once I get some hardware of my own to test with

Using a clean install here, and the ESP8266 board isn't available by default. You need to go into Arduino Preferences, and add an appropriate board manager url to the list, such as https://github.com/toddtreece/esp8266-Arduino/releases/download/1.6.4/package_esptest_index.json
or http://arduino.esp8266.com/stable/package_esp8266com_index.json
Only after doing this was the ESP8266 option available in the Board Manager.
