Let's say I have a few sensors and LEDs connected to a raspberry Pi and I want to make a fully connected GUI on a desktop(PyQT) for it. So I can see the sensor values, toggle the LEDs and so forth.

What is the most optimal way of doing this?

    how do you define optimal? ...... you have provided zero details about the configuration of your system, so the question that you asked is un-answerable – jsotola Mar 22 '18 at 19:25
  • assuming both machines are on the network, a simple client/server method would be pretty easy to pass data back and forth – Chad G Mar 22 '18 at 20:33
  • Sorry for not being clear enough @jsotola. I am just starting out. I didn't explain much about the configuration of the system as I am building it as I go. RIght now there are not even any hardware connected to the GPIO. I was just looking for topics to learn from. – Samiul Hoque Mar 23 '18 at 22:57
  • Thanks alot @ChadG. Took your advice and got the data passing part working. Working on the rest now. – Samiul Hoque Mar 23 '18 at 22:57
  • @scitronboy I found out about PyQT. Looking into it now. Hopefully I can make it work soon. – Samiul Hoque Mar 23 '18 at 22:58

So here was my findings after tinkering around with it all day. Seems I just got the communication part down. Still need to figure out the GPIO end and the client GUI end.

I wrote a simple server/client code using sockets.

server end code:

import socket
s = socket.socket()
host = ''   //IP from the router
port = 12345

while True:
    c, addr = s.accept()
    print ('Got connection from' , addr)
    c.send( 'Response from Orange Pi' )

Client end code:

import socket

s = socket.socket()
host = ''   //IP from the router
port = 12345

I am fairly new to python so I am still digging around to make the GUI for the client end. Will post updates as I progress.
