v2.1 — 2026-06-29

A bug-fix release that makes the color flaps work correctly end to end and the calibration tools honor a module's custom flap set. It is a drop-in upgrade from v2.0 — all endpoints, MQTT topics, and module behavior are unchanged.

Fixes

  • Color flaps are no longer turned into letters. The seven color flaps are addressed by the lowercase letters r o y g b p w (red, orange, yellow, green, blue, pink, white), but the gateway was normalising all lowercase ASCII to uppercase before sending — so a request for blue (b) went out as the letter B. Lowercase letters are still uppercased to match the default reel, except those seven colour codes, which now pass through verbatim. Ordinary text is unaffected (hello → HELLO); lowercase is now meaningful for colours (b → blue flap).
  • Calibration Wizard and Character Map now reflect a module's custom flap set. Both were hardcoded to the default 64-flap reel, so a module on firmware v31+ with a custom character set or flap count was still calibrated against A B C …. They now read the module's live character set and flap count (via the combined A dump / /api/flap/all) and use them throughout — the map labels, the Wizard's per-flap glyph and progress, the whole-board walk, and the default per-flap step positions (spaced by the module's actual flap count, not a fixed 64).
  • Live Display renders colour flaps. A flap currently showing a color now appears as a colour swatch on the Live Display wall, matching the Character Map, instead of printing the bare color letter.
  • Lowercase is visible on the Display tab. The Send Text and Send Single Character inputs no longer force-uppercase what you type on screen, so you can enter and see the lowercase color codes you are sending.
  • The web UI no longer serves a stale page after an update. The embedded page is now sent with Cache-Control: no-cache, so a normal reload always loads the new UI after a firmware flash — previously the browser could keep serving the cached HTML/JS, making an update look like it had no effect.

Compatibility & upgrade notes

  • No API, MQTT, or wiring changes; backups are unaffected. The custom-flap-set calibration display requires module firmware v31+ (older modules use the fixed 64-flap default reel, exactly as before).
  • Upgrade the gateway over-the-air as usual (Settings → firmware update), then confirm the version badge in the header reads v2.1. Because of the caching fix, do one hard refresh (Cmd/Ctrl + Shift + R) after this upgrade; subsequent updates refresh on a normal reload.
