Guys plz healp me. I have finished flashing Esp8266 esp12e with Nodemcu frameware, with standed flasher. Now when i start the device an error message (Can’t open init.lua). What is that error? how to install it?

Am sure that the device was not broken because it was responding for some commands runned with esplorer.

Checked with the blink code with esplorer and working nice.

But not responding to AT commands?

Any one plz help me what to do?

Thanq

@Gary_Dobbins Thanq for you speed responce

But it was not responding to AT commands, is there any other way to make it work.

Thanq

Nodemcu only takes lua code, not at commands. You could try using the http://ChiliPeppr.com/nodemcu workspace instead of esplorer and it may be more intuitive as to the lua code.

First check what files you have in memory.
I think without being aware of it you hit format.
You simply have the clean memory of files and you must introduce a new file http://init.lua

Nodemcu firmware completely replaces the default firmware, which uses AT commands…

you write LUA code and apply it to the esp8266 to perform the functions you would normally use AT commands for:

The AT command interpreter is just one of the bits of software you can install and run on the esp, so when you replaced that software with nodemcu they went away.

You can enter Lua commands directly into NodeMCU and they will run immediately, or you can use the various tools to create an init.lua file containing the scripts to run at boot time.

or you can replace the whole thing with custom software you write yourself using for example the Arduino IDE with the ESP8266 Board type installed.

Please try John Lauer’s http://chilipeppr.com/nodemcu it makes it trivial to learn NodeMCU and Lua which is a very friendly language.
