ESP8266 Community Forum

- Tue Apr 18, 2017 3:49 am #65045 Hello I flashed my ESP8266 ESP-12E with NodeMCU by raspberry Pi 3 B. All was okay. On

Code: Select allminicom -b 115200 -o -D /dev/ttyS0

I can normally connect but if I want to upload some files by exec command:

Code: Select allpython luatool.py --port /dev/ttyS0 --src init.lua --dest init.lua --verbose --baud 115200

then I get:

Code: Select allStage 1. Deleting old file from flash memory
->file.open("init.lua", "w")Traceback (most recent call last):
File "luatool.py", line 272, in <module>
 transport.writeln("file.open(\"" + args.dest + "\", \"w\")\r")

self.performcheck(data)
File "luatool.py", line 61, in performcheck
raise Exception('No proper answer from MCU')
Exception: No proper answer from MCU

I have connect only RXD and TXD pins, when I'm connecting GPIO0 to GND and run it by baud 9600 its the same, please help me. When I try to the same on ESPlorer then I get double sending a command but not all command. Something like this:

Code: Select allprint('TEST')
print('TES

Guys please help me!
