- Sat Sep 26, 2015 10:15 am #29925 I'm trying to set a simple project - esp01 with the dht11 module (temp. + hum.)

when flashing the default FW: nodemcu_integer_0.9.5_20150318 I'm able to connect to my router, but the dht module is not recognized. ( dht.read11() fails).
when I was trying other FW versions - I tried custom builds and dev builds - the dht module worked, but I couldn't connect to the router. ( getting Incorrect Password error).
these are the FW binaries I was trying to flash:
nodemcu_integer_0.9.6-dev_20150704
nodemcu-master-9-modules-2015-09-07-19-50-36-integer


in both cases I was using the same init.lua + dht11.lua files.

I'm not aware that wifi is broken in current dev or even master. Maybe you suffer from old/outdated configuration data when you switched from an old firmware version to a newer one.
If you haven't done already, please download blank.bin as well when flashing a new firmware. This should erase all configuration data in the flash and will allow you to set up the wifi connection from scratch.
