    ESP32-Based Soil Monitoring System Occasionally Loses Sensor Readings After Several Days

    I hadn't considered counter or timer overflows, so I'll definitely review those along with the memory usage over time. The project does use interrupts for sensor sampling and communication, so I'll also double-check that those handlers are behaving correctly. At the moment, I've only been...

    ESP32-Based Soil Monitoring System Occasionally Loses Sensor Readings After Several Days

    Hi everyone, I'm working on a remote soil monitoring project using an ESP32 that measures soil moisture, temperature, and ambient humidity. The system uploads data periodically over Wi-Fi and is powered by a small solar-charged battery pack. The project works well initially, but after running...

    STM32-Based Data Logger Experiencing Occasional Communication Errors After PCB Assembly

    Hi everyone, I'm developing a small STM32-based data logger that collects sensor readings and periodically sends the data to a host system over UART. The firmware appears stable, but after moving from a development board to a custom PCB I'm occasionally seeing corrupted packets and missed...
