B4R Question DHT22sensor.Read22 not return 0 if failure

[jcohedman]

Hellow!
When I'm reading DHT22 sensor with an ESP8266, if it is connected, gives the values, but if desconnected, don't return 0, continues with the last values measured...
What I'm doing wrong?

DHT22pin1.Initialize(5,DHT22pin1.MODE_INPUT) 
DHT22sensor1.Read22(DHT22pin1.PinNumber)            'Reading the DHT22 measure
    hum1=NumberFormat (DHT22sensor1.GetHumidity,0,0)      'Get humidity from readed measure
    temp1 =NumberFormat (DHT22sensor1.GetTemperature,0,0)  'Get temperature from readed measure

Hi Jcohedman.
when measure pin was sisconnected you must see -999 in hum1,temp1

Hi, Vali!
thanks for your answer, but unfortunately this is the problem, it must return 0, and don´t...
Btw, I'm using DHT22.
Meanwhile, I'm changing the ESP8266 for a ESP32S, to see what happens.

Hi jcohedman
I thought about your problem.
I think your problem will be solve if you Initialize measure breafor each read11.

ok ?
