to knxd

Hi there,

I have several embedded linux running same configuration on both product.

They share the same individual adress and one of them became deaf and mute to the knxd bus.

Could someone can explain where is the mistake in my configuration ? I know that i'm doing wrong by having two products with the same individual address but I try to understand why knxd seems to filter frames

Why do you share indiv.addresses? That basically never make sense. Stop doing it.

To prevent cycles. When it *knows* that a packet with source address A must arrive from bus X, because that's where it has seen it coming from previously, a packet with the same address suddenly arriving from bus Y will get dropped.

This is reported when you turn on log output.
