Hello,

I've tried to work with DS18B20 and the 0.9.6 firmware. Fot this I used this example script https://github.com/nodemcu/nodemcu-firmware/wiki/nodemcu_api_en-(dev096)#owselect . The "search address" part works well. I got different addresses from my DS18B20. But the ow.read and ow.read_bytes function returns only 255 (FF). With different ESP modules. With/without external pullup resistor. With ow.skip or ow.select. Nothing works. Only a 0.9.5 firmware works well.

Has someone an idea.

Thanks Detlef.

Hello.

I'm facing same issue.
The device address and information is received well, but versions 0.9.6 return just 255 when using any read methods. That didn't happen in previous releases.
