@marcosinigaglia I am also getting “XXXX” as uuid Below is the details, I got from retrieveServices method.

{ characteristics:
    [ { properties: { Indicate: 'Indicate' },
        characteristic: '2a05',
        service: '1801' },
      { properties: { Read: 'Read' },
        characteristic: '2a00',
        service: '1800' },
      { properties: { Read: 'Read' },
        characteristic: '2a01',
        service: '1800' },
      { properties: { Read: 'Read' },
        characteristic: '2aa6',
        service: '1800' },
      { descriptors: [ { value: null, uuid: '2902' }, { value: null, uuid: '2901' } ],
        properties: { Notify: 'Notify' },
        characteristic: '2a37',
        service: '180d' },
      { properties: { Read: 'Read' },
        characteristic: '2a38',
        service: '180d' },
      { properties: { Write: 'Write' },
        characteristic: '2a39',
        service: '180d' } ],
   services: [ { uuid: '1801' }, { uuid: '1800' }, { uuid: '180d' } ],
   id: '7B:E7:B4:3E:AF:3D',
   name: 'Default' },

Is this is possible to read/write with this data ? If possible can you please tell me which characteristic and services uuid to pass as an argument to retrieveServices method. I was using one IOT device which gave 16-bit binary value, so I could able to read/write with that device. But now I am trying to get data from an Android device(version 6.0.1) which returns XXXX as uuid.

Thanks in advance.

@vldgeorgiev In my case i am trying to scan a smart wrist band. I am actually unaware of the advertised services and characteristics. Other than the app developed by the wrist band firm . I am facing the same issue even in native android built applications
