Bug fixes

**BambuFarm 1.5.0 is out ** This one's the big quality-of-life update. **The reopen bug is gone.** You know the one — close the app, open it back up, and everything's empty / "disconnected" / acting like you got logged out. Pull-to-refresh would fix it but it shouldn't have happened in the first place. Fixed at the root. **Widget text is finally readable.** Big complaint from a few of you with farm-mode setups: 9pt grey text on the home-screen widget was hard to read at a glance. Now you can pick S/M/L/XL and toggle high-contrast white. Settings live in your Profile. **Camera sync modal is way smaller** and scrolls cleanly on iPhone SE / mini. **History tab no longer crashes** when you open it (Moti + React 19 incompat — fixed by removing it; functionally identical, just no fade-in animation). Cancelled prints now correctly show as completed instead of "Printing now" forever. Color filter handles every filament code now. **Login is less rage-inducing:** - Email auto-trims and is case-insensitive (no more invisible-space wrong-password) - Tells you when Bambu's servers are down vs. when your credentials are actually wrong **Lock-screen Live Activity:** - Timer no longer resets after a pause (huge for long prints) - Ghost activities that wouldn't go away → finally cleaned up automatically **Big farms get the love too** — smoother scroll on older devices, less battery drain when the app's open with many printers, less network chatter on every refresh. **Power user tip:** if anything ever feels stuck in cache, tap "Version" in your Profile 5 times to wipe it. Update via the App Store. Feedback always welcome — drop it here or in Discord.

Live Activities — Fully Reworked Live Activities now work entirely from the backend. Start a print and track progress right on your Lock Screen and Dynamic Island — no need to keep the app open. Progress updates automatically with real-time percentage, countdown timer, and estimated finish time. Pause, resume, cancel, and finish events update instantly. Live Activity Thumbnails Your Live Activity now displays a thumbnail image — either a live camera snapshot from BambuBridge or the 3D model cover from Bambu Lab. Live Activity Customization New settings to personalize your Live Activities: Choose between camera snapshot or 3D model cover Toggle ETA finish time on or off Toggle layer count display HMS Error Codes — Complete Overhaul Upgraded from 268 to 4,239 error codes using Bambu Lab's official database. AMS Lite errors now properly decoded instead of showing raw codes. Pause reasons display the actual issue (filament stuck, AMS error, front cover removed) on both notifications and Live Activities. Stability & Crash Fixes Fixed app showing "No printers found" after long background or cold start Fixed crash on startup from corrupted token storage Fixed crash from TcpSocket write on closed connections Added global error handler to prevent silent crashes LAN camera retry now uses exponential backoff instead of spamming every 5 seconds Fixed SecureStore access errors when app is backgrounded Fixed progress bar hidden when print is at 0% (preparing state) Remote Camera Improvements Cameras now properly reconnect when returning from background Auth token refreshed on reconnect (fixes stale token after hours) Zombie socket detection — forces reconnect even if connection appears alive BambuBridge Updates Bridge now connects local MQTT to all printers for command relay Improved network scanner reliability Command relay infrastructure for future printer control features Under the Hood 67 unit tests covering critical server logic Automated pre-push testing on every deploy Cleaner server logs — noisy camera/WebSocket logs moved to debug level Server memory leaks fixed (frame cache and throttle maps cleaned on disconnect) Orphaned database records cleaned up on user unregister Token refresh triggers 5 minutes before expiry React Query retry with exponential backoff on failed API calls

What's New in BambuFarm 1.4.4 Live Activities — Fully Reworked Live Activities now work entirely from the backend — no need to keep the app open. Start a print from your Bambu printer and the Live Activity appears automatically on your Lock Screen and Dynamic Island. Progress updates every 2.5 minutes with real-time percentage, countdown timer, and estimated finish time. Pause, resume, cancel, and finish events update instantly with accurate status. Live Activity Thumbnails Your Live Activity now shows a thumbnail image. If you're running BambuBridge, it displays a live camera snapshot from your printer. Otherwise, it shows the 3D model cover image from Bambu Lab. The image is captured when the print starts and displayed throughout the entire print. Pause Reasons on Lock Screen When a print pauses, the Live Activity now shows the actual reason — filament runout, AMS error, front cover removed, or user-initiated pause. No more guessing why your printer stopped. Live Activity Customization New "Live Activity Appearance" section in Settings: • Choose between Camera snapshot or 3D Model cover for the thumbnail • Toggle ETA finish time on or off • Toggle layer count display on or off Improved Layout The Live Activity lock screen banner has been redesigned with the thumbnail on the left, printer name and job title clearly visible, and the countdown timer left-aligned for easier reading. Reliability & Stability • Added 55 unit tests covering critical server logic • Automated pre-push testing — every deploy is verified before going live • Cleaned up server logging for better debugging and less noise • Fixed multiple edge cases in activity token synchronization • Fixed incorrect 1-hour ETA fallback when remaining time wasn't available yet Under the Hood • Activity tokens now sync via the AppDelegate during background launches • Push-to-start tokens used correctly for LA creation only • Progress updates throttled to stay within Apple's Live Activity budget • Server includes cover URL in push payloads for NSE image download • Camera frame endpoint added for BambuBridge snapshot serving

What's New in 1.4.2 Real-Time MQTT Sync Print status now syncs directly with Bambu's cloud MQTT broker. Progress, pause, resume, and completion are instant and accurate — no more stale data. Live Activities & Dynamic Island Live Activities trigger automatically when a print starts, even with the app closed. See real-time progress, countdown timer, and job name on your Lock Screen and Dynamic Island. Pauses show the reason, cancels display correctly, and activities dismiss when the print finishes. All server-driven via push notifications. Pause Reasons & HMS Alerts See exactly why a print paused — filament runout, AMS jam, clogged nozzle, motor overload, and more. Error codes decoded into plain English. Shown in push notifications, Live Activities, and the printer detail view.
