During November 2025, Viric contributed to the meshtastic/firmware repository by developing a power-resilient deep sleep feature with auto-restart for RAK4630 and RAK4631 devices. This work focused on enhancing unattended deployments by enabling devices to automatically recover after power restoration, addressing reliability challenges in remote environments. Viric implemented robust power-loss handling using low-level C++ programming and embedded systems techniques, including system-off states and LPCOMP for brown-out recovery. The update also centralized device-specific configurations in variant.h, streamlining cross-device support and maintenance. Although the work spanned one feature, it demonstrated depth in hardware interfacing and embedded reliability engineering.
