Hi all,

Im currently using the heartrate sample projects notification function on Btool by writing 01:00 to handle 0x0013, i was wondering how can i change the rate of notification and sampling thank you.

    Hi Husain,

    I'm not familiar with handle 0x0013 offhand, but the logic applies to any notification characteristic. For example, in heartrateservice.c,

    // send heart rate measurement notification
    heartRateMeasNotify();

    Is sent by the heartRatePeriodicTask. So, you would just increase the rate of the periodic task (timer). However, you should be aware of the sampling/reporting requirements if you are intending to be compliant to the Heart Rate Service adopted specification.

    Best wishes

    You can change "#define DEFAULT_HEARTRATE_PERIOD 2000" in heartrate.c, in which 2000 means 2000 mill-seconds.
