Please add UDP socket to the network module and ad Serial Ports support

Hi Samir,
congratulations for the great work you are doing, it is certainly the most interesting Lua distribution for the Windows platform that is currently in development. Going into detail, I noticed that the net module does not support UDP. Of course, we are talking about an old protocol but still very useful especially in intranet interfacing with microcontrollers (i.e. ESP32) in broadcasting mode, overcoming the complexity of MQTT. Would it be possible to include UDP in the development possibilities? Since we are at it, it would not be bad to have support for serial ports. These two aspects would greatly increase the usability of LuaRT in the development of applications for interfacing with microcontrollers. Thanks for the work you are doing and congratulations.

UDP is already implemented in the native lua socket module:
This is a simple broadcasting sender example:
local socket = require "socket" local address = "192.168.1.255" local port = 12345 local udp = socket.udp() udp:settimeout(0) udp:setpeername(address, port) udp:send("UDP Message 1") udp:send("UDP Message 2") udp:send("UDP Message 3") udp:send("UDP Message 4") udp:send("UDP Message 5") print "UDP message sent (Broadcasting)"

It works very well!

...and this is a simple server:
`local socket = require("socket")

udp = socket.udp()
udp:setsockname("*", 12345)
-- nil or a negative value blocks indefinitely:
udp:settimeout(10)

while true do
data, ip, port = udp:receivefrom()
if data then
print("Received: ", data, ip, port)
udp:sendto(data, ip, port)
end
socket.sleep(0.01)
end`

Yes all Lua binary modules are 100% compatible with LuaRT

I will see to add UDP support to LuaRT Sockets

For serial ports, it's on my todo list 👍️

Thank you Samir,
you are the best!
