@ho-dor i don't think 0x0f is the correct I2C address for DHT11 sensor. I checked on this link where address for all I2C sensors are specified https://learn.adafruit.com/i2c-addresses/the-list . @CloudyPadmal please guide. Also some of the sensors in #1840 are not I2C. How to communicate with such sensors?

[ho-dor]

@neel1998 what about DHT11, is it i2c? It's not in the list you have mentioned

[neel1998]

@ho-dor i am not sure. But mostly all the i2c sensors have SDA and SCL pins. Which are not there in DHT11. Still we have to check once. But mostly it might not be i2c

DHT11 is not an I2C sensor. Checkout Arduino library and see how it's implemented.

Not I2C

I suggest we close this for now and work on it later. DHT11 sensor works in a different principle and I think a direct firmware support would be more appropriate than trying hard with Android. I'll follow up with this issue later and closing this for now
