Direzione di ricerca

Start by reading the UDP sync receive path in wled00/udp.cpp, especially the per-segment sync loop. Check how incoming colour is applied to the main segment versus effect and palette on other segments. Done means changing the sender's primary colour updates every receiver segment in the described setup; verify with two WLED instances and multiple segments.

Descrizione

bug
What happened?

When two or more WLED instances are synced over the network and a segment uses the Solid effect, changing the primary colour on the sender does not update the color on the receiving instances. The receivers stay on their old colour. Effects, palette, speed and intensity all sync correctly — only colour fails to sync. It's most obvious with Solid because the colour is the whole output. I have more than one segment configured, and the segments other than the main segment never get the new colour.

To Reproduce Bug
  1. Set up two WLED instances on the same network with Sync send/receive enabled (same sync group), "Segment options" sync left OFF (default).
  2. On both, create 2+ segments and select them all, set effect to Solid.
  3. On the sender, change the primary color.
  4. The sender updates all segments; the receiver's non-main segments keep the old colour.
Expected Behavior

The new colour should persist across all segments, in the same way effect / intensity etc. do.

Install Method

Binary from WLED.me

What version of WLED?

WLED 16.0.0

Which microcontroller/board are you seeing the problem on?

ESP32 with ethernet

Relevant log/trace output

Anything else?

Not hardware-specific — it's in the UDP sync receive path in wled00/udp.cpp. The incoming color is only applied to the main segment, while the per-segment sync loop applies effect/palette but not color. I have a fix and will open a PR.
