Blynk server connecting issue

[ajitnayak87]

Dear all

I have used arduino platform and nodemcu unit. I have uploaded the below code earlier its working well.
I have updated IDE Know all arduino option related to Nodemcu setting upgrated.

With this upgrade i could not able to establish connection between blynkserver and nodemcu.

ESP8266 GPIO pins info, restrictions and features

hi blynkers! the esp8266 mcu is widely used in iot projects. however, most gpio pins on this mcu have special / multiple functionality and are not safe to use in all circumstances. these “features” are still not well documented and not explained in a friendly manner for newbies. i see lots of cases when the “issues” are simply caused by not knowing which pins to use in which case.
