February 2026 monthly summary for Asset-Tracker-Template and SDK NRFXLIB. Focused on stability and correctness in power management and battery modeling, with contributions linked to two critical fixes across repositories. Delivered targeted fixes with clear commit references, improving reliability in production systems reliant on accurate power channel behavior and battery state restoration. Key features delivered: - Power Module Channel Subscription Deduplication fix in Asset-Tracker-Template (commit df1fb35046670e5137dd1c252accc1ebbe082dfd). This eliminates duplicate subscribers to PRIV_POWER_CHAN, reducing runtime churn and potential channel misbehavior. - NRF Fuel Gauge Initialization Precedence Fix in sdk-nrfxlib (commit af7ca900c8ab00cef24c4991d151f70c1d687855). Upgrades to v1.1.1 and ensures a provided battery model pointer overrides stored state during initialization for correct restoration of battery state. Major bugs fixed: - Duplicate subscriber issue in Power Module channel leading to redundant subscriptions; resolved to improve stability. - Initialization precedence bug in NRF fuel gauge library that could cause incorrect battery state restoration when restoring from stored state; fixed by ensuring pointer precedence during init. Overall impact and accomplishments: - Improved power management reliability and battery state accuracy across production deployments, reducing runtime failures and debugging time. - Facilitated smoother state restoration and more predictable battery behavior in critical power scenarios. Technologies/skills demonstrated: - Embedded C development, patch coaching, and rigorous commit hygiene (signed-off commits). - Cross-repo coordination between Asset-Tracker-Template and sdk-nrfxlib, including version upgrades (NRF Fuel Gauge to v1.1.1) and initialization ordering. - Focus on business value through stability, reliability, and predictable state management in power/battery subsystems.
