Well, without additional info all I can do is to provide a (useless) suggestion that your either your sensor is bad, or some connections are incorrect.
Please go to README and scroll down to HOW TO REPORT BUGS section for a more useful info.

I don't believe it's a bug in your code but just wondering if during your time working with the max30102 you saw this same situation.
from max30102_by_rf.
Yes, I did see this happening when I mistakenly connected the INT port to a wrong MCU pin. :)
So here is another suggestion: buy or borrow the M0 Adalogger (or an equivalent MCU), download free Arduino IDE, and prove to yourself that all the hardware and connections work properly. Then you will be able to debug your Python code on Raspberry Pi. Is it interrupts? Maybe the I2C communication is faulty? I have never used Raspberry, thus I have no idea how this platform handles I2C.

Appreciate the feedback about the interrupt pin. I've modified my setup to not require the interrupt pin, instead it reads the FIFO read and write pointers to determine if data is available. But it's a good idea to try to completely copy your hardware setup, I will see about getting an M0 adalogger.
Did you ever encounter issues with cold fingers not producing proper red and ir signals?
from max30102_by_rf.
No, I have not noticed any issues tied to finger's temperature. But, on the other hand, it's quite difficult to find extreme cold here in California. :)

Ok, just wondering. Thanks for your help!
