When RBridge runs on a Raspberry Pi it indicates its mode by several blinking patterns of LED0 (this LED usually indicates flash activity which is disabled when RBridge runs).
This slow on-off blinking pattern indicates that RBridge is either idle or it is running as a registry:
A “single short off” blinking pattern indicates that RBridge has an active connection over IPv4:
A “double short off” blinking pattern indicates that RBridge has an active connection over IPv6, this looks like this:
We hope you like this little feature as much as we do 🙂 !
