I used to work in the Group Fitness (gym electronics) space and this is exactly how some BLE heart rate monitors get around the problems with otherwise requiring the host to connect to 20+ devices to capture their data. Put heart rate into the Manufacturer-Specific region of the advertising packet and boom, no one needs a connection.
Problem is that it's non-standard, so every device packages the data a different way.
- qdot76367 2y agoOh lord do I have some stories there. Way back in the nascent Quantified Self days, I ran http://openyou.org http://openyou.org, which was basically "Buttplug for consumer health devices" (I mean I guess Buttplug is Buttplug for a specific type of consumer health device but, well, you get the idea). There's a god damned heart rate profile standard in the bluetooth spec AND YET I'm not sure I ever actually worked on a device that used it. :|
