From Sensor to Dashboard — Without a Line of C My previous projects used the STM32F446RE — a capable workhorse, but one that needs an external LoRa radio module wired up separately. When I decided to go deep on LoRaWAN, I wanted a chip where the radio was part of the silicon itself. The STM32WL55JC1 delivers exactly that: an ARM Cortex-M4 application processor and a sub-GHz radio coexisting on the same die, talking to each other over an internal SPI bus that never leaves the package. ...

When industrial facilities need to monitor equipment and environmental conditions, they often face a challenge: different systems speak different languages. A temperature sensor in one part of the building might use Modbus TCP, while the HVAC system uses BACnet/IP, and wireless sensors communicate via LoRaWAN. Getting all this data into one place typically requires expensive proprietary gateways or complex integration projects. I built a solution that brings these three protocols together on a single platform, using open-source tools and commodity hardware. ...
