This week we finished our full draft SLDR and delivered a practice presentation to get early feedback from coaches and peers. We refined our messaging, tightened the architecture slides, and clarified the system-level interactions between the LoRaWAN node, the environmental sensors, the gateway, and cloud. Outside of SLDR prep, we also made significant progress on firmware and hardware development for our RAK3172-based environmental node. Firmware has been successfully brought up and we have begun the schematics for some initial custom PCB designs.
