I have been played for few hours with my new NodeMCU board.
I was able to flash FW using esptool.py (I'm under Linux)
Then I played a bit with ESPlorer by connecting NodeMCU on /dev/ttyUSB0 ; uploaded lua script successfully..

But suddenly, I don't know exactly what I did (but I certainly did something wrong) ; but the Node MCU is not responding like before (1/2 hours before):

Code: Select allTry to open port /dev/ttyUSB0, baud 9600, 8N1
Open port /dev/ttyUSB0 - Success.
sending:<CR><LF>
sending:<CR><LF>


CRLF is sent without endless, and I can't upload Lua scripts anymore.

I can bypass that "error" by disabling "FW autodetection" from ESPLoarer, but then §I fails with "Waiting answer from ESP - Timeout reached. Command aborted."

What should I do?

Thank for suggestions/support.

I don't know what is the difference between Windows "nodemcu-flasher" mode compared to esptool..

So topic is Fixed.
