During February 2025, Håkon Hanssen focused on improving the reliability of modem initialization for nRF91 development kits in the sdk-nrf repository. He addressed a startup failure issue by adjusting the timing in the modem_shell sample, specifically increasing the pre-read delay from 1500ms to 2000ms to allow additional PDN activation time. This targeted firmware change, implemented in C, enhanced stability for developers working with embedded systems on affected hardware. While the work was limited in scope, it demonstrated careful analysis of device behavior and a practical approach to firmware development, resulting in a measurable improvement in system startup reliability.
