Spectre v0.1.2

Accuracy and feature improvements across cellular, Wi-Fi, Bluetooth, and GNSS.
This release focuses on correctness, with better identifiers, frequencies, and security labels, plus new filters and a richer GNSS view.

Notable Changes

• Cellular channel numbers now map to their real downlink frequency, including 3G
• Fixed cellular band mapping and neighbor-cell identity
• Wi-Fi security shows accurate WPA3 / OWE labels with the cipher, instead of a risk flag
• Added Wi-Fi 7 channel-width support, and hardened Wi-Fi capability parsing
• Vendor lookup from the device MAC for both Wi-Fi and Bluetooth, with a new Wi-Fi vendor filter
• Bluetooth manufacturer names now resolve from the complete company-id list
• Fixed BeiDou orbit classification, and added range rate, ephemeris, and almanac to the per-satellite view
• Added GNSS range rate
• Request local-network access at runtime on Android 17

Spectre v0.1.0

Lots of reliability and correctness improvements over v0.1.0-beta.
The app has been tested on a few different Android devices.

Notable Changes

• Improved GATT connect reliability for random-address BLE devices
• The Bluetooth list stays frozen while a row is expanded, so devices don't move during inspection
• WiFi access points gray out by missed scan count instead of elapsed time
• Cellular scanning recovers automatically when a SIM / subscription sync comes back empty
• Fixed the GSM timing-advance range and step, correcting distance estimates
• LAN host scan rewritten on NIO sockets for faster discovery
• Thread-safety and off-main-thread fixes across WiFi, Bluetooth, and readiness tracking
• Scanners reorganized into per-radio packages
