Hello every one, i have an issue uploading the sketch code from my arduino to ESP8266…
I'am a newbie and i want take data from the sensor and send it to the firebase but I have this error I’m not sure why is doesn’t work ?

Error compiling for board NodeMCU 1.0 (ESP-12E Module).

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

The problem is probably in your code that we cannot see

The easier you make it to read and copy your code the more likely it is that you will get help

Please follow the advice given in the link below when posting code , use code tags and post the code here

If you get errors when compiling please copy them from the IDE using the "Copy error messages" button and paste the clipboard here in code tags

thanks a lot @UKHeliBob this error is due to my syntax, i solved this error,the time to connect to wifi is too long, maybe my wifi is quite slow.

@VienBu, your topic has been moved to a more suitable location on the forum.

BTW, not quite sure how slow wifi can result in compile errors :confused:
