Please make sure you selected the right board.

Thanks !,

I was using the video on youtube, Testing the file, But a bit further in the video. Doas he the settings of the board. after that the code "D1" Error wiln't show,

Now i am only stuck at Serial Montitor with the message>

failed, rc=-2 try again in 5 seconds Attempting MQTT connection...failed, rc=-2 try again in 5 seconds Attempting MQTT connection...failed, rc=-2 try again in 5 seconds... ... ..

It's likely an issue with the MQTT server or credentials you are using. Verify your MQTT adress and the username/password info and try again. Cheers!

I picked this board and I think my problem is fixed.

If that fixed your issue, make sure you hit close issue on this thread

I too had this "issue".

I was using an ESP-01 board and put D0 and D2. But they're not defined as data pins on the ESP-01. So if this is the case you have to just put 0 and 2 for these boards.

Tks. I was using ESP8266 and had the same problem. Changed to ESP-12 1.0, as sudgested by bbrandon, and it all workrd.
