So I just tested this with nRF toolbox on iOS and the HRM example from SDK 10.0. The Heart rate is only updated when a notification is sent from the peripheral.

My peripheral is a BT earphone with heart rate sensor, but let's make it simple. If I stop sending HR data to Nordic APP (HRM from nRF Toolbox) but still be connected, will APP keep repeating the heart rate with last HR value? Is it normal ? I've tried both iOS or Android based smart phone , but both will keep repeating the last value even in my code , I forced to stop sending the HR data.
Thank you

What peripheral application is this? For a normal heart rate strap you would usually stop sending notifications when the HR sensor detects that there is no skin contact. However I'm not sure what sensor you have.

Please be more specific about what you are doing. Which app is this, central, peripheral, nRF51, iOS or Android? thanks.
