Trouble with: setAdvertising heart_rate

Ahh, right. So you have 3 specific things:

• Advertising data - data that's broadcast to everyone
  
• Advertised services - broadcasting 'I can do X', but not containing data
  
• Actual services - data once connected
  
  

Unfortunately Puck.js doesn't let you define advertised services right now - but you managed to find a way around it by explicitly setting the raw advertising data, so it looks like you're sorted :)

I've filed a bug and I'll try and add the ability to set advertised services at some point in the future.
