I've read your Beginner's Guide but still face this ... how to test if the esp8266 is working (not dead)?
Just got one (nodemcu 12E), when I plug it to the usb port, the blue led blinks twice. Installed Arduino IDE on win10 (I have issues with the serial ports on Linux Mint), loaded the ESP addl libraries (.json), tried the basic blink code, getting error "espcomm upload mem failed."
It would be great if there are some steps I can try, to make sure my esp8266 is not dead.
