✅Okay, I got what you want exactly. I am a senior embedded systems and IoT hardware engineer with over 10 years of experience, providing STM32 firmware development, low-power device architecture, LTE/5G integration, GNSS systems, secure bootloaders, and production-ready PCB design. In my opinion, the key to this project is balancing aggressive power optimization with reliable 5G/GNSS performance, especially to achieve the 20-day battery target. I would design a modular STM32L or STM32U + 5G/NB-IoT hybrid architecture with intelligent wake cycles, motion-triggered reporting, adaptive GPS sampling, and secure MQTT over TLS with a lightweight FreeRTOS task structure to keep the firmware scalable and OTA-ready from day one. This project is very similar to my previous works. Recently, I developed a battery-powered LTE-M asset tracker built around STM32L476 with GNSS + 6 sensors, achieving 24-day runtime on a 4200mAh Li-ion battery using motion-based wake-up and adaptive reporting intervals. I also designed a 4-layer PCB with external flash logging (16MB QSPI), implemented secure boot + dual-bank OTA, and reduced BOM cost by 18% during DFM optimization for a 3,000-unit pilot run. Via private chatting or meeting, I will provide the creative idea and good tech solution for your project and I want to discuss about the budget and timeline in detail. Best regards. Yaroslav
