I want to send a variable number (e.g. int 1) from a lua script to Pure Data? How can I do this?
I'm trying [receive] object, but nothing happens.

This is my code in Lua. We also need pdlua to works.

local ginga = pd.Class:new():register("ginga")

function ginga:initialize(sel, atoms)
self.inlets = 1
self.outlets = 1
return true
end

@romulovieira-me In your Pd/bin folder you will find an executable.... pdsend.exe for windows...... or pd.darwin or pd.linux (I think) for other os's.
You can tell Lua where to find it (maybe just copy it into a folder that Lua uses), and call it within your script.
In Pd you would then use [netreceive] to receive the message.
It will probably be a lot easier than creating a socket in Lua.
I don't know Lua.
You would use pdsend (in Python) and [netreceive] (in Pd) like this........ https://guitarextended.wordpress.com/2012/11/03/make-python-and-pure-data-communicate-on-the-raspberry-pi/
You will need to work out how to script the Python equivalent in Lua.
