Alpha 27

Offline Mission Planning

You can now plan missions without connecting to a flight controller first. Open the map, drop waypoints, set up geofences and rally points — all before plugging anything in. When you do connect, your planned
mission stays intact and the Upload button lights up so you can push it to the board. No more staring at a "Connect First" screen when you just want to prep a flight plan at home.

Higher Baud Rates

Added 230400, 460800, 921600, and 1,500,000 baud options to the connection panel. This matters most for future MavFTP log downloads and bulk parameter transfers where the old 115200 cap was a real bottleneck. If
your hardware supports it, use it.

Collapsible Sidebar Everywhere

The connection sidebar can now be collapsed even when you're not connected. Previously it was locked open and ate up screen space whenever you were disconnected. Now you can tuck it away while working on mission
planning or browsing other offline views.

macOS Intel Builds

CI now produces native x64 builds for Intel Macs alongside the existing ARM builds, so older Macs get a proper native binary instead of running through Rosetta.

Alpha 26

New Features

Receiver Configuration Tab

Full receiver setup is now available directly in the MSP Config view for both iNav and Betaflight boards:

• Receiver type selection (iNav: None/Serial/MSP/SITL)
• Serial RX protocol picker with quick-select presets (SBUS, CRSF, IBUS, etc.)
• Channel mapping (RX Map) with visual drag-and-drop reorder
• RC deadband configuration (stick deadband, yaw deadband, throttle deadband, alt hold deadband)
• Inline receiver wizard embedded in Quick Setup transmitter check step - when no RC signal is detected, users can troubleshoot and fix receiver config without leaving the wizard
• Changes integrate with the global "Save All Changes" button and EEPROM write

Serial Ports Configuration Tab

New Ports tab for configuring UART function assignments:

• Visual per-port function toggles (MSP, GPS, Serial RX, Telemetry protocols, Blackbox, etc.)
• Baud rate selection for MSP, sensors, telemetry, and peripherals
• Board-aware UART labels (MATEKF405SE, OMNIBUSF4, etc.)
• Read-modify-write via MSP2_COMMON_CF_SERIAL_CONFIG

MAVLink RC Channels Telemetry

• MAVLink RC_CHANNELS (msg 65) parsing added to telemetry pipeline
• New RcChannelsData type in telemetry store for up to 18 channels with RSSI
• Receiver tab on MAVLink config view updated to use live telemetry

Bug Fixes

MSP Mode Save (Critical)

Modes appeared to save successfully but were empty after reconnect. Two root causes:

• Wrong payload size for iNav - serializeModeRange() was sending 7 bytes (including Betaflight-only modeLogic/linkedTo fields), but iNav expects exactly 5 bytes. The extra bytes caused a silent failure
• FC acknowledged the command but never persisted the data. Now correctly sends 5 bytes for iNav, 7 bytes for Betaflight.
• BOXNAMES response too large for MSPv1 - MSP_BOXNAMES returns ~308 bytes for 28+ modes, exceeding the v1 255-byte limit and causing checksum failures. Replaced with BOXIDS + static flight mode lookup table
  (ported from iNav Configurator's flightModes.js). Betaflight still uses BOXNAMES (shorter response).

RC Channel Order Fix

• MSP_RC returns raw receiver channels in physical order (not standardized). Added reorderChannels() utility using the rxMap from MSP_RX_MAP to display channels in correct logical order
  (Roll/Pitch/Yaw/Throttle/AUX).
• Fixed TransmitterVisualizer channel order (Yaw and Throttle were swapped).
• BetaflightDashboard now shows properly labeled and reordered RC channels.

Transmitter Detection Baseline

• Channel movement detection now uses a captured baseline from the first reading instead of comparing against fixed 1500. This prevents false positives from FC failsafe/default values when the transmitter is off.
• Detection threshold reduced from 100 to 50 for better sensitivity.
• Detection expanded from 8 to 16 channels.

MSP Mutex Race Condition

• Fixed acquireMutex() using capture-then-wait pattern: the new mutex promise is set BEFORE awaiting the old one, preventing concurrent callers from seeing the same resolved promise and bypassing the queue.

Modes Wizard Fetch Reliability

• Sequential fetch with retry for mode ranges, box names, and box IDs instead of parallel Promise.all (MSP mutex serializes them anyway). Automatic retry after 1s if any fail - gives the FC settling time after
  connection.
• Preset selection is preserved if loadFromFC completes asynchronously after user picks a preset.

Protocol Improvements

MSP v1 Jumbo Frame Support

• Added jumbo frame parsing to the MSP v1 state machine. When the length byte is 255, the parser reads 2 additional bytes as 16bit LE actual payload length.
• Checksum calculation correctly includes the jumbo length bytes per iNav's wire format.
• Future-proofs against any other MSP response that exceeds 255 bytes.

iNav Flight Modes Static Lookup

• New packages/msp-ts/src/modes/flight-modes.ts with all 60 iNav flight mode entries (permanentId to boxName mapping)
• boxNamesFromBoxIds() resolves BOXIDS responses to human-readable names without requiring MSP_BOXNAMES

New MSP Message Types

• MSP_CF_SERIAL_CONFIG / MSP2_COMMON_CF_SERIAL_CONFIG - serial port configuration read/write
• MSP_RX_MAP / MSP_SET_RX_MAP - channel mapping read/write
• MSP_RC_DEADBAND / MSP_SET_RC_DEADBAND - deadband configuration read/write
• Extended MSP_RX_CONFIG to parse iNav receiver_type at byte 23

---

UI/UX Improvements

• AUX channel count expanded from 4 to 12 in modes tab and switch names
• Removed stale RX/TX packet counter from AppShell toolbar
• MSP packet counters now tracked in context for accurate toolbar display
• Receiver type selection moved from SafetyTab to dedicated ReceiverTab
• setRawRc log throttling reduced from every 50 to every 500 calls
• Quick Setup transmitter check step now includes inline receiver troubleshooter with protocol hints
