I’v been doing some tests with the harmony gateway app. This does appear to be able to connect. I put a packet sniffer in between so I could see what exactly is being sent. So first off, you are right about the 0 char terminator, which I can’t simulate in fiddler.
Second, I noticed that you are sending 224 data bytes, so that packet is using unix line terminators and puts a couple of spaces in front of the xml elements. I am currently sending 204 bytes as I removed all the spaces and newlines from the xml string. Other than that, I don’t immediately see much of a difference between the requests. Do you know of something else I can perhaps try?
