How to send an array from Python (client) to Java (Server)?
Have you looked at BSON?  It's like JSON, but optimised for a little more speed.
I am using OpenCV on my Raspberry Pi to track circular objects. Then, I want to send the coordinate and radius values in an array of floats across the LAN to the Java program
I can send strings all fine with the code I have, but I'm having trouble trying to send numerical datatypes. What is the correct process for this?
