What is the best way to do inter-process communication in Unity?

I have a heart rate device with some custom software I wrote that I want to use as an input to a Unity game. The problem is that the software is written in .Net 4.5 so I can’t put the code straight into my Unity project. So I’ll have to run it as a separate app and get the data to my Unity game, the question is, how?

I assume I’ll have to create a local TCP server, the next step I’m not sure what would be the best option so I thought I’d ask for some help before I dig a rabbit hole.

There’s not a huge volume of data, just BPM etc. So far I’ve looked at local sockets, message queues and Unity’s networking but I’m not sure which would be best.

Any ideas?

I was working with this as well and I ended up using TCP sockets. I tried using NamedPipes but I guess Unity dose not support it, TCP sockets work pretty well. I would recommend you read up on them as much as possible because they have a lot of gotchas. They work fast enough for sending texts through. MSDN
