Hello, I am experiencing an issue with Pysense 2.0 Light sensor LTR329ALS01, I am attaching the steps to reproduce the issue:

1. turning on the power
2. running the main.py (added just main parts):

   import pycom
   from pysense import Pysense
   from LTR329ALS01 import LTR329ALS01
   ...
   py = Pysense()
   lt = LTR329ALS01(py)
   light = lt.light()
   print(light) # --> (145,23)
   ...
   time_milliseconds = 10 * 1000 # ten seconds
   pybytes.deepsleep(time_milliseconds)

3. the FyPy goes to deepsleep
4. the FyPy wakes up and execute again the code at point 2 as expected
5. the print returns (0,0)

I was expecting at point 5 a tuple with the new light readings instead of zero values.

Hi, Could you post this issue to the pycom-libraries repository instead? We maintain the sensor libraries over there: https://github.com/pycom/pycom-libraries Also, it might be worth mentioning the related forum thread you posted in: https://forum.pycom.io/topic/1462/solved-pysense-light-sensor-shows-zero-after-cycling-through-deep-sleep/ I will close the issue here

sure, thanks for the suggestion!

@StefanoOrdine I am facing a similar issue with the light sensor(LTR-329ALS). Did you find the root cause?
