Using Greybus for IoT
summary
Greybus is the modular RPC protocol from Project ARA, reworked here to run over TCP/IP transport and Bluetooth so a Linux gateway keeps drivers and sensor logic on the host while remote modules expose GPIO class, I2C/SPI controllers and other bundles via manifests. Working code lives in staging and uses Avahi for discovery and GB device simulator for testing; demos partially work but show variable latency, missing remote-wake/power features and no built-in security, so further work is needed.
