Calibration Reference Persistence #34

Open ALEEF02 opened 1 year ago

ALEEF02 commented 1 year ago

https://github.com/adafruit/Adafruit_CircuitPython_SCD30/blob/72c1ccb3c45d6d5cd005bc0bfd792d8e81fc99cd/adafruit_scd30.py#L225 This doesn't mention the calibration persisting on reset like other parameters such as: https://github.com/adafruit/Adafruit_CircuitPython_SCD30/blob/72c1ccb3c45d6d5cd005bc0bfd792d8e81fc99cd/adafruit_scd30.py#L203 I've set the forced recal reference before, and sometimes, but not always it'll reset to the default when I turn off & on the board I'm using. Other times, my recalibration reference persists. Is there sometimes I'm doing wrong or something I can do to ensure it persists? I use the sensor inside & it's a hassle to bring it back outside to recalibrate it.

I have the same issue - it sometimes persists and sometimes resets to 400.
