Ulfi-Bus is a field-bus protocol for connecting home, office or industrial devices, providing easy address configuration even on very constrained devices.
Ulfi is intended to be used on broadcast-like bus architectures, like RS-485 or radio. Using double addressing mode to fulfill contradicting requirements of globally unique addresses and supporting extremely constrained devices at the same time. Security and authenticity is supported optionally in a very thin layer, requiring minimal processing capacity – thus latency – when it is not used.
Ulfi-Bus is currently under development with working prototype, going to be disclosed soon.
