- Sun Feb 15, 2015 11:45 am #9845 I wrote, not too long ago, yet another Python-based ESP8266 lua script uploader for the NodeMCU Lua firmware.
Get it here.
One of the cool things that my script, LuaUpload can do is upload through Telnet to a ESP8266 running the telnet server lua script.
I'd appreciate bug reports, feature requests, and most of all, pull requests. I've not been very active on this project, but I intend to continue developing it, now that I'm not bogged down with work.

EDIT: managed to find it, here.

Tried running it in Win32, under an elevated cmd prompt. Errors:

No sweat. Was just trying things. I think that you might want to add a binary upload option.

Sorry about that, I've updated the readme to be easier to understand

Tried running it in Win32, under an elevated cmd prompt. Errors:

Code: Select allD:\esp8266\luaupload\luaupload.exe upload --port COM1 --baud 115200 text.txt
Could not open serial port COM1 at 115200

This is a general problem with Pyserial, and many Windows programs that use serial.
One of the solutions I've seen is to disable and then reenable the serial port in Device Manager.
Also, could you install pyserial and try using miniterm.py to open a connection?
That would tell me if it's a problem with PySerial or with my program's usage of PySerial.

I think that you might want to add a binary upload option.

Could you elaborate on that? I'd be happy to implement it if I knew more about what you want

BTW thanks for testdriving my code!
