Trouble with: setAdvertising heart_rate

Quick update:

1. Using setService doesn't blow away UART (I think this puck was just taking some time to pick up).
   
2. I've got a heart_rate advertising, but…it's not quite there.
   
   

Note that the value is totally wrong. I'm also trying to connect from a webpage, which doesn't discover that this device has heart_rate (I think it's filtering on the service), but baby steps!
