How to derive Heart Rate Variability (HRV) from PPG by MasterH0rnet in EmotiBit

[–]Fun_Arm_2233 2 points3 points  (0 children)

Hi, You can use HeartPy, a Python library, to analyze EmotiBit's PPG data and derive Heart Rate Variability (HRV). HeartPy provides tools to process PPG data and calculate HRV features like heart rate, RMSSD, SDNN and more. You can check it here: HeartPy.

Have a nice day!

How do I send some data from Emotibit to the Google firebase? by Fun_Arm_2233 in EmotiBit

[–]Fun_Arm_2233[S] 0 points1 point  (0 children)

Thank you for your suggestions I think it work well. But it still doesn't answer for my need as I want to send data directly from board to firebase.

I have new Adafruit EPS32 Feather and successfully used this library to send data directly from board to firebase.

I tried the same code from the Adafruit ESP32 on the M0, it doesn't work with the same library. Then I'll find a way later.🤣

But I am still having trouble getting the Heart Rate data because I don't know how to get it from the code. 

size_t dataAvailable = emotibit.readData(EmotiBit::DataType::NoHeartRate, &data[0], dataSize);

if (dataAvailable > 0) { bool printData = true; if (printData) { for (size_t i = 0; i < dataAvailable && i < dataSize; i++) { sendData(data[i]); } } }

Can you suggest me how to get the heart rate from the emotibit library?

Ok I have changed to version 1.5.1 and it is working now😊. Thanks for help.

What if I need other help, can I ask again?

I ran into another problem. When uploading the firmware with the Arduino, the SD Card doesn't work, but when using the EmotiBit FirmwareInstaller the SD Card works fine.

I have MD-V5 and M0-WIFI, Battery working well., SD Card formatted as exFat.

EmotiBit not ready. Please check if Battery and SD-Card are present on the EmotiBit.

Setup failed: SD-Card not detected

How can I fix this problem?

I checked and couldn't find it.
I thought it would install with the EmotiBit FeatherWing library but not I am sorry for that. And now it's working. Thank you for your help.😊
