EnvisaLink 4 TPI Issues: Regular timeouts

[thanatos0801]

I've been working on a TPI application and for the most part everything is working fine. I'm seeing some issues with the reliability of the connection to the EVL, though. After some random amount of time, the socket read times out, and for several seconds after that, I can't connect at all. Eventually I can connect again, but it takes a minute or two before I can connect again.

Here's the code connection log ->

Any thoughts?

I have seen this exact same issue with the EVL3 for Ademco panel, a lot of users of my software have reported this problem.
The problem doesn't seem to occur with DSC panels.

There are no open tickets nor recent bug reports for the TPI (apart for documentation issues).

If you are a developer you can submit a bug report but you need to also send in a PCAP file (tcpdump) capturing the issue.

Also make sure you are running the latest version of firmware too.

What's the latest version of the firmware and how would I update it if I'm behind? I don't see anything to check for updates in the web panel.

I *think* I may have solved the issue on my own... I'm in long term testing now, but if I'm right and this keeps working, then my issue had to do with the "app nap" feature in OS X shutting down my network connections.
