Hi,
I have wrote some code for my esp8266-12 and it worked fine. But i had to change my windows. After windows installation I downloaded and completed arduino setup and I complied and upload my previous sketch but it doesnt work. I got this error from serial debugging when WiFi.disconnect() going to run in setupAP function.
