Hello,

This error is in serial monitor:

Thx for the help.

You are right @invidia191, latest releases are bugged with ESP8266.

Unfortunally i've tried only to compile and not running, my mistake.

I will fix as soon as possibile

Hi @invidia191 I've just pushed the sources that fix the bug you reported.

I will do further tests before creating a new release. If you want to try it yourself just download the repository as a zip archive and install it manually using the Arduino IDE or you can also overwrite the actual files.

Working perfect, thanks.

But don't understand how to read saved variables and use them in loop. Do you have example ?

[cotestatnt]

@invidia191 in the customOptions.ino the value of variables are loaded at start-up calling the function loadOptions()

For user convenience, the same thing is done when user do a request via the web interface because a GET handler was defined for this purpose dinamically added at runtime as HTML/Javascript option.

As you can see in the source the loadOptions() function use the class method myWebServer.getOptionValue(VAR_LABEL, variable); for each variable you need to load at begin (configurations, tokens, addresses etc etc).

The equivalent method myWebServer.saveOptionValue(VAR_LABEL, variable); can be used to store permanently the value of variable in the config.json file (saved inside flash memory).

Of course this is just an example of how it is possible to use these methods which will then have to be adapted on a case-by-case basis.

However, keep in mind that a flash memory shouldn't be used to save "working variables" which change continuously due to the limit on the number of maximum writes (usually at least 100000)

That is easy. Thought needed arduinojson. Great work !
