I use latest IDE, on home and work PC, original esp8266 library examples working perfectly, easy iot library fail for me.
Can you please tell how to get working IDE ?
ArduinoESP ide developers constantly reuploading new versions, maybe latest is ok now.
and after a bit trial & error also managed to modify and upload a webserver example to an esp-01 module (using my new esp proto PCB and FTDI breakout). Reproducibly, successfully.
Thinking about ditching the whole nodeMCU lua thing in favor of the new, shiny possibilities with many arduino libs for many kinds of sensor...
