Customer:

I cannot upload a sketch to my Croduino NOVA. The upload fails with an error that suggests the libraries may not be installed correctly.

Soldered Support:

This is a compile error, not an upload error. Try updating your Arduino IDE. Your version may be outdated for the new esptool (needed to compile and upload). The latest version is available at https://www.arduino.cc/en/Main/Software

Customer:

I have already updated to the latest version 1.8.5 but the error persists.

Soldered Support:

Check what version of esptool you have by going to Tools > Board > Board Manager, search for “esp”, and update if needed.

Customer:

I updated esp8266 to the latest version and now it works with the Hello Server sketch.
