Hi,
using Raspberry Pi Zero with DHT11 sensor and I am observing this issue:
"A full buffer was not returned. Try again." after running dht_simpletest.py.
I edited values to match DHT11 and P4 (i use)

dhtDevice = adafruit_dht.DHT11(board.D4)

I tested the sensor using the old library and it works (90+ % succ read rate), but using the new library I can barely make one successful request.
Also I tried to increase sleep period to 5 sec with no result.

How should I troubleshoot this?
