Summary

macOS can keep showing a BLE RNode as Paired in System Settings while CoreBluetooth has already rejected the bond (Peer removed pairing information / LTK desync). That left Reticulum stuck “offline”, LoRa GATT (MeshCore/Meshtastic) fighting the adapter, sticky “Bluetooth bond invalid” banners after a successful re-pair, a dead-end Open Admin Bluetooth CTA, and Disconnect & Quit hanging when exclusive GATT release respawned the sidecar.

This PR recovers that path end-to-end:

Sidecar / OS bond recovery

  • Classify Peer-removed / LTK-desync errors (reticulum-sidecar/src/ble/error_classifier.rs).
  • Dispose the cached btleplug CBCentralManager and hold recreation during exclusive RNode bond recovery so dual-central races stop.
  • New /api/v1/ble/handle-ltk-desync path that attempts OS unbond (macOS via blueutil with name/MAC resolution — CoreBluetooth UUIDs alone are insufficient; Windows UnpairAsync; Linux best-effort) and verifies the device is no longer paired when possible.
  • When automatic purge fails, surface copy that sends users to System Settings → Forget (and optionally open OS Bluetooth settings from Electron).

Electron / GATT coexistence

  • Exclusive LoRa GATT hold while RNode bond recovery owns the adapter; MeshCore/Meshtastic connect aborts via shouldAbort instead of spinning on scan_busy.
  • Quit-safe exclusive clear: skip ensurePort / sidecar respawn when the port is already gone or the app is quitting, so Disconnect & Quit exits cleanly.
  • Issue tracker latches LTK desync → recovery IPC; clear bleBondRemoved / pairing-timeout banners when a BLE RNode comes online again (no 5‑minute stale wait).

UI / Admin focus

  • Open Admin Bluetooth expands Flasher → Bluetooth and scrolls to the pairing controls (reticulumAdminBluetoothFocus).
  • Updated i18n for Forget / LTK desync / exclusive-pause hints (brands preserved across locales).

Test plan

  • macOS LTK desync: With a BLE RNode that System Settings still shows as Paired but the sidecar reports unpaired / Peer removed, start the Reticulum stack and confirm exclusive recovery runs (logs: dispose central / handle-ltk-desync / unbond attempt).
  • If blueutil can unpair by MAC/name, confirm OS bond clears and re-pair via Admin → Bluetooth works without a manual Forget; if not, confirm Manual Forget copy + open Bluetooth settings.
  • After a successful re-pair and interface online, confirm the sticky “Bluetooth bond invalid” banner clears without restarting the app.
  • Open Admin Bluetooth from the sidecar issue banner opens Admin, expands the flasher Bluetooth section, and scrolls to pairing controls.
  • With MeshCore or Meshtastic BLE active, trigger RNode bond recovery and confirm LoRa GATT pauses/aborts cleanly (no hang), then resumes after recovery clears.
  • Disconnect & Quit while exclusive GATT hold is active exits the app (no sidecar respawn loop).
  • Regression: healthy BLE RNode connect still works; USB/Wi‑Fi RNode paths unchanged.
  • pnpm run check:reticulum-sidecar / pre-commit green on this branch.

Summary by CodeRabbit

  • New Features
    • Added automatic recovery for Bluetooth pairing desynchronization, including bond cleanup and guidance to Forget and re-pair devices when needed.
    • Added controls to release the Bluetooth adapter during recovery and prevent conflicting connections.
    • Added support for opening Bluetooth settings on macOS and Windows.
    • Admin Bluetooth alerts now open and focus the relevant configuration section.
  • Bug Fixes
    • BLE bond and pairing alerts now clear when interfaces recover or become online.
    • Reconnect attempts pause safely during bond recovery.
  • Tests
    • Expanded coverage for recovery, settings, alert clearing, and reconnect behavior.

…ed state

Detect Peer-removed / LTK desync during exclusive LoRa GATT hold, purge the
stale OS bond when possible, clear sticky alerts after online, and keep
Disconnect & Quit from respawning the sidecar on exclusive release.

📝 Walkthrough

Walkthrough

The change adds BLE LTK desynchronization recovery across the sidecar, Electron IPC, GATT ownership, issue tracking, reconnect logic, and Reticulum Admin UI. Bond removal uses platform-specific implementations, and stale bond alerts now clear after recovery or expiry.

Changes

BLE bond detection and removal

Layer / File(s) Summary
Sidecar bond recovery API
reticulum-sidecar/src/ble/*, reticulum-sidecar/src/api/*, reticulum-sidecar/src/stack/mod.rs
The sidecar classifies BLE errors, removes bonds on Linux, macOS, and Windows, exposes the LTK desync endpoint, and emits BleLtkDesync.
GATT central recovery
reticulum-sidecar/src/gatt/*, src/main/gatt-sidecar-proxy.ts, src/main/index.ts, src/preload/index.ts, src/shared/electron-api.types.ts
The GATT adapter can be disposed and held during bond recovery. New IPC and HTTP paths release the central and clear the recovery hold.
Issue latch clearing
reticulum-sidecar/src/reticulumSidecarIssueTracker.ts, src/main/reticulum-sidecar-manager.ts, src/main/ipc/*, src/renderer/lib/reticulum/*
Bond-removal alerts now use the stale window and can be cleared for interfaces that return online. Renderer interface tracking sends the online names through IPC.
Reconnect and recovery UI
src/renderer/runtime/*, src/renderer/lib/bleReconnectHelper.ts, src/renderer/components/*, src/main/bluetoothSettings.ts
BLE reconnect paths stop while bond recovery holds the adapter. The Reticulum Admin Bluetooth section can be expanded and focused, and supported systems can open Bluetooth settings for manual removal.

Merge Risk: 🟡 Moderate · up to ef9a1

BLE recovery can intermittently leave reconnects blocked or allow Meshtastic activity during exclusive RNode recovery. These material recovery-path races should be fixed before merge; macOS users also retain a manual fallback when automatic unpairing fails.

🟠 Major · Stop the reconnect cycle during RNode bond recovery. · useMeshtasticRuntime.ts:2526-2538

src/renderer/runtime/useMeshtasticRuntime.ts:2526-2538
🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Stop the reconnect cycle during RNode bond recovery.

When bond recovery becomes active, the scheduled callback still invokes attemptReconnectRef.current(). Each invocation increments reconnectAttemptRef.current, enters the RF controller backoff/open cycle, and then fails because connectGattWithScanBusyRetry aborts before GATT connection. The next scheduled attempt continues until the budget is exhausted, after which the BLE exhaustion latch disables automatic reconnect.

BLE_ADAPTER_LEASE_RELEASED_EVENT can clear the latch and start a new cycle, but only when Reticulum releases the adapter lease. The bond-recovery path holds that lease, so clearing bond recovery does not guarantee an automatic restart. Otherwise, the user must reconnect manually or resume from power state.

Add the matching guard:

🛡️ Proposed fix to mirror the MeshCore guard
 const scheduleMeshtasticReconnectAttempt = useCallback(() => {
   meshtasticRfReconnectRef.current.scheduleOwner(() => {
+    if (connectionParamsRef.current?.type === 'ble' && getReticulumBleBondDesyncActive()) {
+      console.debug(
+        '[useMeshtasticRuntime] abort reconnect schedule — RNode bond recovery holds the adapter',
+      );
+      isReconnectingRef.current = false;

+      meshtasticRfReconnectRef.current.endAttempt();

     }
     void attemptReconnectRef.current();

Document the name request field.

BleUnbondBody in reticulum-sidecar/src/api/interfaces.rs accepts an optional name, and src/main/reticulum-sidecar-manager.ts sends it. On macOS the UUID address cannot be unpaired without it. Add it to the body column so callers know it is required for CoreBluetooth UUID addresses.

Track recovery-hold application separately from the desync flag.

If the BleLtkDesync handler runs before the reticulum:status update, the shared flag is already true. The status handler then skips prepareReticulumBleRnodeConnect(), so it does not acquire the Reticulum scan lease for that recovery. The main-process latch still releases the LoRa GATT central separately.

🔧 Proposed fix
-        const firstLatch = !getReticulumBleBondDesyncActive();
+        const firstLatch = !bondRecoveryHoldAppliedRef.current;
         setReticulumBleBondDesyncActive(true);
         if (firstLatch) {
+          bondRecoveryHoldAppliedRef.current = true;

Clear bondRecoveryHoldAppliedRef.current in the existing branch that releases the recovery lease. Also clear it alongside each existing setReticulumBleBondDesyncActive(false) reset so sidecar teardown cannot leave the ref latched.

Pass the newly latched interface to recovery. When another bond-removal alert is already latched, the handler can select that existing interface instead of the interface from the triggering line. It then sends the wrong address and name to /api/v1/ble/handle-ltk-desync, which can unpair the wrong RNode.

Derive the newly added interface name at recordSidecarOutputLine and pass it to handleBleLtkDesyncLatch. Match the /api/v1/interfaces row by that exact name.

application separately from the desync flag, and document the optional
macOS display-name field on handle-ltk-desync.
Lock the bondRecoveryHoldAppliedRef firstLatch path so BleLtkDesync cannot
silently skip the Reticulum scan lease without a source-contract failure.

Invalidate stale bond-recovery work before reacquiring the scan lease. The recovery IIFE can resume after status cleanup, disconnect, or teardown has reset the latch and released the lease. It can then acquire the Reticulum scan lease with no guaranteed later release. Add a recovery generation, increment it on each recovery clear, disconnect, and teardown, and check it before and after prepareReticulumBleRnodeConnect().

- Around line 2528-2536: Update the BLE reconnect flow around
attemptReconnectRef.current() and GattSidecarProxy.connect() so activating the
bond-desync latch supersedes the active reconnect generation and controller.
Recheck getReticulumBleBondDesyncActive() after each asynchronous open boundary
and before retaining, wiring, or configuring the device; when active, invalidate
the attempt and clean up the late transport instead of continuing.

bondRecoveryHoldAppliedRef and prepareReticulumBleRnodeConnect to track a
recovery generation, incrementing it whenever recovery is cleared, disconnected,
or torn down. Capture the generation when starting the async recovery IIFE and
validate it before and after reacquiring the Reticulum scan lease; if stale work
acquired the lease, release that acquisition with notify: false.
