GATT service on RuuviTag

I tried several times but nothing changed. Here is my new code :

var Ruuvitag = require("Ruuvitag");

Ruuvitag.setEnvOn(true);

NRF.setServices({
  0x1800: { // heart_rate
    0x2A6E: { // heart_rate_measurement
      notify: true,
      value : [Math.round(Ruuvitag.getEnvData().temp)]­,
    }
  }
}, { advertise: [0x1801] });

setInterval(function () {
  NRF.updateServices({
    0x1800: {
      0x2A6E: {
        value : [Math.round(Ruuvitag.getEnvData().temp)]­,
        notify: true
      }
    }
  });
}, 1000);

Here is what I get with my phone :

It's says no service. And in the section "TX characteristic" I can see an error from the javascript interpreter but I'm not able to read it because it goes too fast.
I don't understand why there is an error even with the IDE disconnected. The code looks very simple.
