OctoSK6812+Artnet+ 280ledsSK6812 x4: Only first 3 universes ok, next are lagging about artnet

Closing this as was resolved in pjrc thread.
Note: would require implementing artsync

I am having the same issue - I took a look at the pjrc thread and @lagelat ended up using the BlackLED library. Is there no way to leverage your library and have over 3, lag-free universes?

[natcl]

It's totally possible to have more than 3 lag-free universes, it depends on the software that is used for sending. What is your exact setup ? That being said supporting Art Sync packets would be nice. This would be more at the sketch level than the Library level. I'm a bit busy at the time so would welcome a PR for this.

[natcl]

I just updated the library with preliminary artsync support.
I have no hardware to test now so it would be great if you could test:

Make sure you read the full thread on pjrc too as you may need to increase buffer sizes in the Artnet library.

Reopening this issue until I have confimation that artsync works

Hi,
I had a similiar issue today and started debugging it... I'm sending 10 universes (as 10 udp packets with 530 each), but the universes are received in a rather strange order. I printed the incomingUniverse whenever there is an Artnet Packet available - I made a new line whenever Universe 0 appears, so the output looks like this

to me it seems that this is an issue rather with how Arduino handles the UDP packets... any idea about how to workaround this?
