- Mon Sep 04, 2017 2:12 am #69721 I have download a new lua firmware from the build service and I upload it in my nodemcu(LOLIN). The upload is done correctly (tools for upload Esptool.py). The command which I gave in esptool for upload the firmware is

Code: Select allesptool.py --port COM6 write_flash -fm dio -fs 32m  0x00000 nodemcu-dev-17-modules-2017-09-03-19-48-56-integer.bin


When I open the ESPplorer and try to communicate with node it says:

Code: Select allCan't autodetect firmware, because proper answer not received (may be unknown firmware).
Please, reset module or continue.
boot mode:(3,6)

I can understand what is mean and how I can solve this.
Have any suggestions?

Normally i'd get a response like that if the BAUD rate was incorrect.
Try different settings.
