Is there some Espruino example that sends Advertising of state (for example) of 4 analog inputs each 3 seconds ?
In meantime sleeps ?

The easiest is probably just:

function update() {
  var data = [
    analogRead(D2)*255,
    analogRead(D3)*255,
    analogRead(D4)*255,
    analogRead(D5)*255,
  ];
  NRF.setAdvertising({},{
    manufacturer:0x0590,
    manufacturerData:data
  });
}

setInterval(update, 3000);

Thanks to help me! Today i compiled your ESPRUINO to NRF51822 (a chineses beacon) and run it. I can see with your WEB IDE the NRF51822 after scanning. Wheni try to connect say "CONNECTING" and nothing happens! Any tip ? Thanks!!!!!!!!

Which board file you started with?
I tried a the Micro:bit firmware on a Xiaomi humidity sensor with nRF51822, and did work at first try.
What kind of beacon? Can it provide enough energy to the uC? Although a single coin cell should be enough, but still...

Hummm, good tip to use the Micro:Bit firmware :)
I will compile with that! Did you compile it ?
I used this attached!

I had gave up to use the ESPRUINO and choose Nordic SDK C where i make work the NRF51802 and NRF51822.

But, now! I want to back to ESPRUINO!!!! Much better! I will test soon and thanks AkosLukacsPatreon

There is an official downloadable build for the Micro:Bit https://www.espruino.com/Download
I used that first with the 51802, and after that built my own with (removed the microbit specific code).
Here is the thread with more info: http://forum.espruino.com/conversations/333666/ and the board file: https://gist.github.com/AkosLukacs/d37aa8663943dbd976279fc4cfa7c785
