- Sun May 01, 2016 1:25 pm #46628 I have an ESP-12 that I would like to program with the Arduino IDE. Is this possible and what firmware would I need on the device e.g. NodeMCU or AT?

Some people got same kind of confusion : they uploaded Blink sketch, and were still trying to use AT commands.
Only one firmware can be uploaded at one time. But that doesn't means that you can not write your own AT commands parser builtin into you sketch, or any other parsers.
