Santosh Kumar Grandhi worked extensively on system-level service management and build system refactoring across the rdkcentral repositories, including rdkservices, iarmmgrs, tr69hostif, bluetooth_mgr, and meta-rdk-halif-headers. He focused on decoupling deprecated components, such as irmgr and pwrmgr, to streamline dependencies and improve maintainability. Using C++, CMake, and systemd configuration, Santosh removed obsolete code, standardized plugin integration, and enforced reliable startup ordering for services like the Bluetooth Manager Daemon. His work enhanced build determinism, reduced cross-module coupling, and improved power management reliability, demonstrating a deep understanding of embedded systems, dependency management, and cross-repository version alignment.

Monthly summary for 2025-08 focused on the rdkcentral/meta-rdk-halif-headers repository. Delivered essential version alignment for pn-iarmmgrs-hal-headers by bumping PV from 1.0.12 to 1.1.0 and updating SRCREV to f03e69447a6a68905700af07b03ee1f5c0bbd3f2; includes removal of outdated pwrmgr changes as part of a refactor/version alignment task. This work reduces upgrade risk and improves downstream compatibility for dependent projects.

In July 2025, delivered a reliability-focused enhancement to the Bluetooth subsystem by enforcing startup ordering with the power management service. The Bluetooth Manager Daemon (btmgr) now depends on the power manager service (wpeframework-powermanager.service) via a Requires relationship, and the previous After dependency has been removed to ensure the power manager starts first and is required for bt_manager operation. This aligns with RDKEMW-3905 and is implemented through two commits: d5db274d492b09eb59aa0f127b1e45bc0d2f1b22 and 1c14ece6390a4c79d6a3992a7956799cff9cd44a. The change reduces startup race conditions, increases boot determinism, and stabilizes Bluetooth initialization across reboot scenarios.

June 2025 monthly summary focusing on key accomplishments across rdkcentral/bluetooth_mgr and rdkcentral/meta-rdk-halif-headers. Key features delivered include decoupling Bluetooth Manager from power management, simplifying startup dependencies and reducing coupling; major bug fixes include power management headers cleanup to prevent misconfigurations and build issues by updating iarmmgrs-hal-headers, with corresponding SRCREV update. These changes improve startup reliability, build determinism, and cross-repo maintainability. The work demonstrates proficiency with systemd service directives, Yocto/BitBake metadata, and header/version management across repos.
