January 2026 monthly performance summary for AMP repositories. Delivered MTU exchange interface enhancements across amp-embedded-infra-lib and amp-hal-st with targeted refactors, tests, and better GATT integration. The changes emphasize maintainability, consistency, and reliability in MTU negotiation, enabling faster feature delivery and improved BLE communication stack.

September 2025 monthly summary for philips-software/amp-hal-st: Delivered reliability and security hardening improvements in the Bluetooth stack. Key features delivered: GapCentralSt Initialization Reliability via asynchronous standby scheduling; this schedules the GapCentralSt standby state using an event dispatcher after setup to improve startup robustness. Major bugs fixed: GapSt Security Policy Enforcement, enforcing mitm=0 and iocaps=none to tighten security posture. Impact: reduced startup flakiness, stronger security baseline, and clearer policy compliance for Bluetooth components. Technologies demonstrated: asynchronous event-driven initialization, security policy enforcement, commit traceability, and robust initialization sequencing. Business value: lower operational risk from startup failures and improved security compliance for critical Bluetooth functionality.

In August 2025, the amp-hal-st repo delivered extended security mode support in GapCentralST, enabling three levels of SecureConnection (notSupported, mandatory, optional) and introducing a mapping helper to translate GapPairing::SecurityLevel to an internal SecureConnection enum. This change clarifies security behavior, enhances maintainability, and paves the way for flexible customer scenarios without API churn.

July 2025 performance summary: Delivered API renames to PairAndBond across embedded infra and BLE stack to standardize secure pairing and bonding APIs, aligning headers, sources, proto definitions, and dependencies. Close collaboration across amp-embedded-infra-lib and amp-hal-st with minimal surface area impact. No critical bug fixes reported; instead focused on API standardization, reliability improvements, and test/mocks alignment. This reduces future integration risk and improves developer experience, security semantics, and system reliability in pairing/bonding flows.
