Red Grid Link v1.2.1 — Reliability & Navigation

What's New

Red Grid Link v1.2.1 — reliability and navigation update.

Bug Fixes

• Fixed Field Link session creation — resolved iOS Bluetooth adapter state detection that prevented session start even with Bluetooth enabled. CoreBluetooth's CBCentralManager initially reports unknown state; the app now filters this out and waits for a definitive state.
• Field Link service initialization — transport state listeners now properly wired at startup

New Features

• Persistent waypoint list — save, rename, and manage multiple waypoints (SharedPreferences-backed)
• Relative bearing arrow — arrow now points the direction to turn, not just compass bearing
• Resection and Dead Reckoning tools now integrate with the waypoint system

Improvements

• New app icon design (network-star with corner brackets)
• BLE transport debug logging for connection troubleshooting
• Demo mode for screenshots (Washington DC coordinates)

Stats

• 783 tests passing, 0 warnings
• 0 errors in static analysis
