I first bought one nodeMCU dev kit 1.0

then recently bought 2 boards V3

so, the first one I was able to control its GPIOs with LuaLoader control interface and couldn't run codes

with esplorer I could upload blink code


then, I changes to work with Arduino boards, and now I tried to setup the new boards and couldn't get them to work

I don't know what is the problem??

I tried to upload blink code with Arduino IDE and there was red dots while uploading the code, and the uploading fails with Arduino IDE

I don't know if I ruined the boards burning them with Arduino IDE ..

and I now i'm focusing on esplorer and lualoader with not so much success

last night I could control GPIO with lualoder control interface and today I can't upload codes and can't control the led with lualoader interface

also, working with esplorer give not success messages

1. when connecting esplorer I get this message:
"Can't autodetect firmware, because proper answer not received."

2. when uploading a lua file which contain blink code, I get this message:
"Uploading to ESP file ledblink.lua...Waiting answer from ESP - Timeout reached. Command aborted."

any suggestions?

Termite is pretty good. http://www.compuphase.com/software_termite.htm

Try 74880bps to see if the boot loader is saying anything when you press the reset button. Try some other rates - 9600 and 115200 are the others most likely to reveal something.

74880 is a non-standard rate but termite and some other apps will let you type it into the field and will work with it.

second, I had the first board working before months. now it's not working and I get the fail messages I post earlier.

they should show up on your computer as an rs232 device. a com port.
