e131 support?

[cobyhausrath]

Hi-
Are there any tricks to using e131 input vs OPC? I thought I had it working once before but now the only LED output I see is all off. The demo mode stops so I do think it is receiving some kind of data.

I see where you mentioned before that this was an 'experimental' feature - so maybe my issue is not something you've run across yet.

I'm using Lightjams, which outputs e131 & Artnet but not OPC. I've had some success with using OLA on the Beaglebone to bridge Artnet->OPC but I've been running into some addressing limitations (and some inconsistent startup states) there, so that's not been a great total solution either.

Here's the log from ./opc-server:
