Sir...I have a dataset containing red and infrared values... but how many ever times i calculated spo2.... all the values are below 80 only... like 60,70 etc

Hello,

Now the data will be streamed as a character device to the node created at /dev/iio:device1
read the data to a file.

cat iio:device1 > file.txt

I have enabled the MAX30102 sensor in same way, but streaming is not working.

What is the wrong with my flow ?

root@ninou-desktop:/sys/bus/iio/devices/iio:device1# cat in_temp_raw

379

root@ninou-desktop:/sys/bus/iio/devices/iio:device1# cat in_temp_scale
