Hello, My issue is similar to this question . I’m currently using v0.13.1, and as discussed @ here , “multi-segment UDP sync” should work as of v0.13. When the following is set in cfg.json "if":{"recv":{...,"seg":true,"sb":true} (i.e. receiveSegmentOptions and receiveSegmentBounds, resp.) things s…

I probably should be banned from this forum! The issue actually lied in my cfg.json settings – I was directly editing the file (rather than using the browser’s Sync Interface), and it turns out that I had overlooked the "btn":true requirement for the sender! None of the naïve hackery I proposed in …

Sorry guys, Actually sync’ing individual presets works… this is how I achieved this already! It must have slipped my mind as I did it quite some time ago… I’m re-inventing the wheel and I just have to figure out what I’ve messed up in this new implementation… Regards, Gbd

I think I’ve identified the issue. But since I haven’t yet fully analyzed the pertinent WLED internals, I’ll leave the final say to the maestros. When a preset change is due to UI, or API over HTTP, or API over serial communication, callMode == CALL_MODE_DIRECT_CHANGE (notifyDirect == true). This …

One more thing: It seems that with UDP sync, it’s best not to omit the {"stop":0} segment objects when sending preset JSON API. While omitting these objects – in the interests of more compact data transfers – may not cause problems when remotely updating the state of a “stand-alone” WLED instance, …

Thanks for posting this info. @gbd - I’m wondering if you have any pointers for me on firing UDP packets at WLED to control individual segments. I can control basic stuff like brightness and FX, but it only seems to apply whatever the selected segments are, rather than being assignable through the…

@beatKeeper Do you mean explicitly packing WLED multi-segment preset JSON into a UDP message from a custom/stand-alone program (just like udp.cpp::notify() does), and then sending this to a WLED instance?

Would it be heresy to simply replace CALL_MODE_BUTTON_PRESS with CALL_MODE_DIRECT_CHANGE? As in: void decodeIRJson(uint32_t code) { ... cmdStr = fdo["cmd"].as<String>(); jsonCmdObj = fdo["cmd"]; //object if (jsonCmdObj.isNull()) // we could also use: fdo["cmd"].is<String>() { ... …

Basically, yes. I’m using a Python script to fire UDP packets at a WLED instance. Until I figure out what I’m doing, I’m putting this at the byte level, manually creating the data payload to make sure I know what I’m changing. So in that sense I’m pretending that I’m another instance of WLED noti…

@beatKeeper What version of WLED are you using? Multi-segment UDP sync support was introduced in 0.13 . However, you should be using at least v0.13.1 (since v0.13.0 is not recommended – has a “critical” bug w/ presets creation)…

@gbd - Just want to be clear. I can make this work firing JSON at the WLED - controlling individual segements. Just trying to figure out how to get the same result through a UDP packet so it’s faster.
