How to get the puck.js to refresh its battery level during adverising

Hi all,

I am using puck.js in advertising mode with the firmware version 2v01 an I am pretty new in using puck.js. I started with the code:

NRF.setAdvertising({
  0x180F : Puck.getBatteryPercentage()
},{name: "puckName", interval: 1000});

I used a constant voltage generator to simulate the drop of the battery level. After I had changed the voltage from 2,9 V to 2,7 V, I waited days along but the puck.js didn't refresh the battery level (it stays 100%). On the other side, if I connect to Espruino Web IDE and upload the code, than the battery level is refreshed immediately, showing some 80% for 2,7 V.

How can I get the puck.js to update the battery level during advertising? Is it possible to configure the interval, like once per day.

I have also tried the solution suggested in this Forum:

NRF.setServices({
  0x180F : { // Battery Service
    0x2A19: {  // Battery Level
      readable: true,
      notify: true,
      value : [Puck.getBatteryPercentage()]
}}},{
  advertise: [ '180F' ]
});

In this case I get the empty service data (i.e. any battery level shown)

Thank you in advance!
