Level up with LoRa
summary
Prototype: battery-powered LoRa electronic door plates built from a Raspberry Pi Zero with LoRa HAT and later compact LoRa modules, connected to multiple gateways and a network server. Software requires porting Arduino examples, available C libraries are thin, and circuit diagrams sometimes omit critical pin links. Surprises: adaptive data rate (ADR) breaks range during walks, a gateway firmware bug broadcasts downlinks to all nodes, and a development board shows 10× higher power draw than expected, slowing tests under duty-cycle limits. Raspberry Pi Zero with LoRa HAT worked but is awkward for low-power final units.
