  Ok thank you so much it works ! Just a last question : if I want to use another service than that of heart rate should I use heart service and just change the name or there is a specific service ?

  When i delete the NRF.updateServices function I get no error. But I still can't see the service.

  Ok, I understand I can't put the characteristic I want in a random service.
  I tried to follow the requirement for the heart rate service but I still have the same problem. It's says Unable to find the service with UUID 0x2A37.

  var Ruuvitag = require("Ruuvitag");
  
  Ruuvitag.setEnvOn(true);
  
  NRF.setServices({
    0x180D: {
      0x2902:{
        value: 0,
        read: true,
        write: true,
      },
      0x2A37: {
        notify: true,
        value : [Math.round(Ruuvitag.getEnvData().temp)]­,
      }
    }
  }, { advertise: [0x180D] });
  
  setInterval(function () {
    NRF.updateServices({
      0x180D: {
        0x2A37: {
          value : [Math.round(Ruuvitag.getEnvData().temp)]­,
          notify: true
        }
      }
    });
  }, 1000);

  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.

  When I'm connecting to RuuvTag with nRFC app on android I can see service but I can't see the characteristic.

  Hello,
  I'm trying to set up a GATT service on the Ruuvitag. I used the Espruino's documentation to find that code :

  var Ruuvitag = require("Ruuvitag");
  
  Ruuvitag.setEnvOn(true);
  
  NRF.setServices({
    0x1800: {
      0x2A6E: {
        notify: true,
        value : Ruuvitag.getEnvData().temp,
      }
    }
  }, { advertise: [0x1801] });
  
  setInterval(function () {
    NRF.updateServices({
      0x1800: {
        0x2A6E: {
          value: Ruuvitag.getEnvData().temp,
          notify: true
        }
      }
    });
  }, 1000);
  

  But when I run it on the Ruuvitag, I got the following error from the javascript console :

  Uncaught Error: Unable to find service with UUID 0x2a6e
   at line 8 col 4
    });
     ^
  in function called from system
  

  I don't know what i'm doing wrong. Thanks for helping me.
