bangle.js: pairs-only support - #358
Conversation
adds a notify-class entry for nordic uart service (the generic serial pipe bangle.js exposes over an espruino JS repl, no byte-level record format at all). pairs anything advertising the service, connects, archives every chunk raw. zero derivable signals — same shape as the oura/ble_hrs entries.
Reviewer's GuideAdds experimental Bangle.js support by matching the generic Nordic UART Service, subscribing only to TX notifications, and banking every received chunk as raw bytes without writes, decoding, signal declarations, or offload checkpoints; the pairing and profile UI clearly communicates the broad device match and undecoded behavior.

Hey - I've reviewed your changes and they look great!
Sourcery assessment
Needs a human reviewer. The adapter persists every notification chunk as raw bytes, so reverting stops future collection but does not remove data already written to raw_archive; that accumulated data would need a bounded cleanup. It introduces no decoded measurements or irreversible device actions, so an ordinary implementation problem should otherwise be repairable.

📝 WalkthroughWalkthroughAdds experimental Bangle.js support through Nordic UART notifications. The adapter forwards raw notification chunks without decoding or handshakes. The registry, BLE sync host, background sync, and pairing UI expose Bangle.js as a generic notify-only device. ChangesBangle.js support
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to Bangle.js background sync can wait indefinitely for a BLE secondary-link slot, which may cause headless synchronization to exceed its allowed runtime.

adapter passed to BandHost.

yielded by link.notify(kNordicUartTxChar) and pass it through the emitted event

raw_archive.captured_at instead of _nowSeconds() when available.

- Around line 273-276: Update the banglejs category description branch in the
category blurb mapping to use the established AppLocalizations string instead of
a hardcoded English literal, matching the localization pattern used by the
surrounding branches.

BangleJsLink connects, gives the watch a bounded window to print whatever it prints, banks every chunk verbatim, disconnects. Wired into the profile devices screen's sync button and the background sync piggyback, same shape as the ring. forgetDevice now tears this link down before dropping the row instead of falling through to a disarm() that knows nothing about it. Also localizes the picker's Bangle.js blurb (it was the one branch bypassing AppLocalizations).

Mid-window disconnect used to hold the secondary-link slot for the full 20s regardless, since run() was fire-and-forget. Future.any against the window lets an early stream end (host.run never rethrows a stream error, only completes) finish the sync sooner.

Every runHeadlessSync wake paid the full ~20s window unconditionally, sequentially after the WHOOP drain, even for a paired watch that has nothing to say. Gate it behind a 20-minute cooldown persisted in SharedPreferences, same pattern as the staleness cooldown above it.

adds Bangle.js as a pairable band. pairs, connects, banks raw notifications, never writes to the peripheral. no decoded signals yet, experimental until real hardware confirms it.
Summary by Sourcery
Add experimental, pairs-only support for Bangle.js and other devices exposing Nordic UART by connecting briefly and preserving notifications as undecoded raw data.
