HRS demo UUID values

[Bret Foreman]

I've got the HRS demo running on my nRF51 DK board and I can see it updating heart rate info using nRF Toolbox on my phone.

I've got some (Python) test code running on my Windows 11 laptop trying to get heartrate notifications. I can scan and see the "Zephyr Heartrate Sensor" and I can connect to the device to see the services which I print below:

0000180d-0000-1000-8000-00805f9b34fb (Handle: 25): Heart Rate


Now I want to get notifications from one of the characteristics (like Heart Rate or Battery).
What UUID should I use when I register my notification callback?

My Zephyr version is 2.3.0. My DK version is 3.0.0.
