Trouble with: setAdvertising heart_rate

@Gordon yeah, I've been reading through the specs (and parsing existing data).

I know (hmm "know", not sure that's accurate!) that sending a value of 0x06, 0x2c should send the right flags to say the heart_rate monitor is connected and the heart rate is 44bpm.

I was thinking something like this:

NRF.setServices({
  0x180D: { // heart_rate
    0x2A37: { // heart_rate_measurement
      broadcast: true,
      readable: true,
      notify: true,
      indicate: true,
      value : 0x2C06,
    }
  }
})

Which does kinda work, but I also believe the device needs to advertise it has heart_rate services - which this doesn't seem to be doing, otherwise filtering for the service doesn't seem to work (or certainly the demo page I'm working from doesn't see it)
