Sorry for my misunderstanding, A simple IDE with lua editor and serial console is under development.

No problem, thanks for your reaction.

If you are working on an IDE that means that there is a function in the firmware that allows the uploading of a text file to a lua file on the ESP.

I'm quite happy to use my own editor for editing the lua scripts on my PC, I now just need a way to upload.

Can you please share information on the upload facility in the current firmware with us, or is that a secret?

Thank you for your understanding, the so called IDE is as simple as a serial console plus an editor.
A tool/script read a file(say init.lua) line by line. and send the line to serial with

Code: Select allfile.write([[line text here]]).

example: init.lua has this(in your pc)

Code: Select allprint("hello world")

then the tool read from init.lua, found this line

Code: Select allprint("hello world")

it will send some thing to serial like this:

Code: Select allfile.open("init.lua","w")

Code: Select allfile.write([[print("hello world")]])

Code: Select allfile.close()

there is no black magic, ide just do this automatically for you.
if you are know some language can open a serial and communicate with it, you can write your "IDE".
just make sure do not write to serial too fast, wait for the coming back prompt '>'.

python upload.py filenameonesp filenameonpc ip 8888

now coding a c# project, can list files, can read files and can upload files also can send commands

planning to add an interrupt for gpio0 to start the server, so when you push the button you get into scriptloader mode after download, will restart and close the server used for uploading

mostly done

but no experiance on mac

I'm not sure if this is the best place to ask this but I'm using the lua web server and running into a problem. I can connect but only 2 times before I get a MAX_SOCKET error. I can't figure out how to release the socket after sending the data. I've tried conn:close() but no joy. This is the lua script I'm trying to use:

Code: Select allsrv=net.createServer(net.TCP)
srv:listen(80,function(conn)
conn:on("receive",function(conn,payload)
print(payload)
door="open"
if gpio.read(8)==1 then door="open" else door="closed" end
conn:send("<h1> Door Sensor. The door is " .. door ..".</h1>")
conn:close()
end)
end)

MAX_SOCKET is 5.
A connection will closed in 180 seconds if it's inactive.
I will do more test on net module to find out why conn:close() doesn't work.
My experience is a Chrome will initiate 3 or 4 connections to host, if click on "refresh" too fast, the MAX_SOCKET is reached easily.
