HIDS, ANCS and HRS. How to stop heartrate measurements when app closed?

[Vladimir]

Hi

I am use hids, ancs and hrs services together with bonding. Phone should hold the connection with device. I am enable heart rate sensor when notification is enabled, but the notification state will not change to disabled if app is closed. I can't measure the heartrate continuously because of battery.

1). How to solve this conflict good?

2). Is there some methods to disable notifications when app is closed?

3). Is it possible to do not save cccd in fds using peer manager or reset cccd when disconnect?

Thanks

1) Depends.

2) Just disable notification when you close the app.

3) Yes. But you may need to modify nrf SDK files or a clever BTLE event filter.
