setting properties- UDP or Telnet

[bob755]

Hello,
I want to set a number of properties such as ailerons, rudder throttle etc from an exterlan Python script which receives inputs from an Arduino controller acting as a Joystick. I've been testing both the generic protocol with UDP and Telnet.

UDP is supposed to be more efficient than Telnet but is it possible to set certain properties using the generic protocol or do I have to send all the properties each time when only one changes?
Is this going to create an overhead? With Telnet one can set a single property when needed.

I'm wondering if there would be a performance issue when continuously sending 10 or so properties.
Which is the best approach?

Hello,

With generic protocol, I didn't find a way to send only part of properties describe in the xml protocol file.
But i am sending to FG only when almost one property have change.
I am building the "string" with value of each properties to be sent, compute a MD5 hash of the string and compare with the old one from previous loop process.
if the hash is different, data are sent
