Can you please tell why do you want to send the heart rate with such small time interval?
>>"I am getting heartRate value using HrssSetHeartRate(heartRate); function. Now heartRate values are printing per second on CySmart App screen."
--> How frequent your function HrssSetHeartRate(heartRate) is setting heart rate? Are you using any dedicated hardware to measure the hart rate?
The idea is in the code example, you have to call the API HrsSimulateHeartRate() which calls HrssSendHeartRateNtf(connHandle);
at a desired interval you want to send the heartrate notification from the PSoC 6 device to your phone.
Thanks and regards
