What would be the best way to change the Android heart rate monitor from the ECG chip to the optical

In my application, the MAX32620HSP is going to be wrist mounted. It is not feasible to attach the leads to a chest strap, so I wish to change the Android app heart rate monitor to the optical chip instead of the ECG one. What would be the easiest/best way to change the code in both the FW and the app so that the heart rate displayed would be from the optical chip instead of the ECG?

Thanks

Glenn

Could you do this ?

Hello Glenn,

Currently there is not an algorithm within the HSP FW to convert the raw optical data into a heart rate value. In the following link under "Design Resources", there is a mbed project that contains an algorithm that could be tailored for the MAX30101 optical chip on the HSP.

Once the heart rate value is obtained, via the algorithm, one could transmit this instead of the ECG value, or add an additional characteristic that contains the value.
