This hands-on workshop introduces the LoRaWAN® Relay feature using STM32CubeWL and the NUCLEO-WL55JC development board. Attendees will configure and test relay-based communication, send live data to a ChirpStack network server, and explore how LoRaWAN Relay can help extend network coverage. The session also demonstrates how STM32CubeWL simplifies rapid application development and end-to-end LoRaWAN validation.
