Jan 1, 2026January 2026: Delivered a focused cleanup in ArduPilot/ardupilot by removing the RC over network capability in the AP_Periph module. The change reverts the prior RC networking addition, eliminating initialization and update paths for network-based RC inputs and removing the associated class and methods. This streamlines the codebase, reduces maintenance burden, and aligns with the project’s stability and security goals.

Aug 1, 2025August 2025 (ArduPilot/ardupilot) delivered high-value flight features, reliability improvements, and expanded testing/telemetry capabilities. The results strengthen safety and operational resilience while enabling richer telemetry and testing workflows. Key features delivered: - CAN frame playback with Lua scripting support and extended DroneCAN frame transmission to support bus playback scenarios using logged CAN frames (CAN_playback.lua). - VTOL/quadplane arming and recovery improvements, including an in_recovery flag on the roll controller and an option to disable IMU consistency checks while ICE runs to improve arming under noisy conditions. Major bugs fixed and robustness improvements: - Parameter handling robustness and concurrency: fixed initialization of flags in AP_Param find() and mitigated data races by hiding parameters during loading to ensure correct visibility. - Build stability and SITL tooling adjustments to suppress non-fatal warnings and resolve SITL build issues. Enhancements to telemetry and logging: - Enhanced blackbox logging for FlightCoach with new BBX1/BBX2 logs and a dedicated Log_Write_Blackbox function to improve telemetry display. Networking and connectivity: - Networking and LTE reliability improvements including non-blocking TCP, pending checks, timeout handling, LTE CMUX/CPSI resilience, is_pending socket methods, RSRQ/RSRP fixes, and a 3-second TCP connect timeout for more robust remote operations. Testing and simulation: - SITL simulation tuning (motorboat throttle normalization -1 to 1) and autotest site expansion with ANUSC coordinates for Lake Burley Griffin. Overall impact and business value: - Increased safety and arming reliability in environments with noisy sensors, richer telemetry for diagnostics, more robust networking in variable conditions, and improved SITL testing fidelity. These changes reduce operational risk, accelerate debugging, and enable more reliable mission execution.
