Changelog

All notable changes to the BLE-Reticulum project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

[0.2.2] - 2025-11-15

Added

  • pipx installation support with automated D-Bus dependency handling
  • BlueZ LE-only mode configuration in installer (prevents BR/EDR fallback)
  • Scanner watchdog to detect and recover from Bluetooth stack corruption
  • Service UUID filtering for more efficient peer discovery
  • Pre-built wheel support for Pi Zero W Python 3.13 (saves 20+ min install time)

Fixed

  • Connection race conditions from concurrent connection attempts to the same peer
  • BlueZ D-Bus state corruption after connection timeouts/failures - devices can now reconnect after blacklist period
  • Scanner interference causing "Operation already in progress" during connections
  • GATT server race where services weren't available on D-Bus before first connection attempt
  • D-Bus disconnect monitoring switched to ObjectManager with polling fallback
  • Peripheral disconnect cleanup preventing new connections after hitting peer limit
  • Identity mapping cleanup on disconnect (prevents stale peer tracking)
  • RSSI sentinel value filtering (-127 from BlueZ)
  • Columba Android compatibility (filter 1-byte keepalive packets)

Changed

  • Refactored to driver-based architecture (future Windows/macOS/Android support)

[0.1.1] - 2025-11-10

Fixed

  • Release workflow: Use gh release create for atomic release creation to prevent asset upload failures with immutable releases. Previously, softprops/action-gh-release created releases and uploaded assets in separate operations, which failed when repository rules made releases immutable immediately.

[0.1.0] - Unreleased

Added

  • Installation system

    • Cross-platform installer script (install.sh) supporting Debian, Ubuntu, Arch Linux, and Raspberry Pi OS
    • ARM architecture support (32-bit armhf and 64-bit arm64)
    • Custom configuration directory support via --config flag
    • Python symlink resolution for correct interpreter detection
    • Automatic PATH configuration for user installations
  • BlueZ configuration automation

    • Automatic BlueZ experimental mode enablement (fixes BLE connection issues)
    • Bluetooth adapter auto-power-on functionality
    • rfkill auto-unblocking for Bluetooth devices
    • Systemd service integration with proper permissions
  • CI/CD infrastructure

    • GitHub Actions workflows for automated testing
    • Multi-distribution testing matrix (Debian, Ubuntu, Arch, Raspberry Pi OS)
    • ARM architecture testing on Raspberry Pi OS
    • Non-interactive installation mode for CI environments
  • Installer robustness

    • Root/non-root detection with appropriate sudo handling
    • Graceful degradation when systemd unavailable
    • Virtual environment detection and support
    • Compatibility with PEP 668 (externally-managed-environment)
    • Platform-specific dependency handling (libffi-dev for 32-bit ARM)

Changed

  • Improved error messages and user feedback during installation
  • Enhanced logging for troubleshooting installation issues

Fixed

  • Path handling for system vs. user installations
  • Permission issues with Bluetooth capabilities (setcap)
  • Dependency resolution across different Linux distributions
  • PyGObject version conflicts on Arch Linux

[2.2.0] - Unreleased

Added

  • Protocol v2.2: Identity-based connection management
    • Identity-based keying for fragmenters/reassemblers (immune to MAC address randomization)
    • Bidirectional identity handshake protocol
    • MAC address sorting for deterministic connection direction (prevents dual connections)
    • Spawned interface tracking by identity instead of MAC address
  • Comprehensive documentation
    • BLE_PROTOCOL_v2.2.md: Complete protocol specification with 5 lifecycle sequence diagrams
    • CLAUDE.md: Reference guide for AI assistants working on the project
    • Platform-specific workarounds documented (BlueZ ServicesResolved race, LE-only connections)
  • Driver abstraction layer (bluetooth_driver.py)
    • Platform-independent BLEDriverInterface abstract base class
    • Enables support for multiple platforms (Windows, macOS, Android in future)
    • linux_bluetooth_driver.py: Linux implementation using Bleak + bluezero

Fixed

  • BR/EDR fallback prevention: Retry ConnectDevice() on every connection to force BLE-only mode (commit 7809d9c)
  • Advertisement packet size: Removed device name from advertisements to stay within 31-byte BLE limit (commit b503718)
  • Logging consistency: Redirect Python logging to RNS format for unified output (commit ae7c028)
  • MTU retrieval: Added get_peer_mtu() method to driver interface (commit 2a34efc)
  • Identity handshake: Restored detection for peripheral connections (commit 88bb2fc)
  • Redundant reads: Pass peer identity via callback to eliminate extra GATT reads (commit d1d94e5)
  • Service UUID filtering: Re-added service UUID filter in discovery (commit 7af5e2d)

Changed

  • Fragmentation/reassembly now keyed by 16-byte identity instead of MAC address
  • Connection direction determined by MAC address comparison (lower MAC connects to higher)
  • Interface spawning based on peer identity (prevents duplicate interfaces for same peer)

[2.1.0] - Unreleased

Added

  • Initial BLE interface implementation
  • BlueZ support via Bleak (central) and bluezero (peripheral)
  • MTU negotiation with 3-method fallback
  • Packet fragmentation/reassembly for MTU-based transmission
  • Automatic peer discovery and connection management
  • Exponential backoff for connection failures

Known Issues

  • MAC address randomization can cause connection issues (fixed in v2.2.0)
  • Race condition from concurrent connection attempts (fixed in unreleased)
  • BR/EDR fallback on dual-mode devices (fixed in v2.2.0)

Version Numbering

  • Major version (X.0.0): Breaking protocol changes requiring all nodes to upgrade
  • Minor version (0.X.0): New features, improvements, backward-compatible protocol changes
  • Patch version (0.0.X): Bug fixes, documentation updates, no protocol changes
