Abstract: We design a low-power STM32F103-based GNSS terminal that prioritizes NB-IoT uplink and falls back to a LoRa-to-Ethernet gateway when cellular attach or TCP setup fails. An RTC-driven wake → acquire → package → upload → sleep loop with compact, newline-delimited JSON payloads reduces airtime and energy. Layered design and power gating extend lifetime, while the LLCC68/W5500 gateway transparently bridges bytes to a TCP server. Results show robust uploads under heterogeneous connectivity with minimal terminal complexity.
