@Foxy7 @dirceusemighini @wwwired I looked at the xDrip+ code yesterday and found that it is storing heart rate in a data base. I can see it on my xDrip app and it's steady and consistent. xDrip send glucose readings to Aaps, so I'll look at that next to see if heart rates can be sent in a similar way.
Interesting, this data came from the watch integration? AAPS send data to xdrip using notifications, I don't know how this work, but If you are looking for it I would look for the sensors that are plugged into xdrip to send this bg data.
