I feel like there’s enough commonality in the problems that we could drive people toward a fast solution instead of toward the forum.
In the specific case of deprecated mesh, the firmware and hardware is still out there and we can certainly hope that Particle will continue to provide documentation even if there is no support. In a calculator, it would only be a fork in the internal state machine and that fork would only be operational for deviceOS v0.8(?)-1.6.
From a more global perspective, I feel like there have always been undocumented LED codes. For instance, the following all contain some kind of pattern which was relevant but is not currently documented:
- Photon setup flashing cyan with a "quick red burst" (now orange burst) [Solved]
- Spark core doesn't goes from white pulse to flash blue (blue light never appear)
- Borron 2G/3G Blinking 12s blue at start, than endless blinking green
- Spark core doesn't goes from white pulse to flash blue (blue light never appear)
- Flashing White LED, Can't Connect
