Ok, that was clear to me. I don't know where you read that i want my
own RSSI? That would just make no sense.

Maybe i should point out, what i am trying to do :)
I need the RSSI values for distance measurements between the nodes. So
what i need is not a "quality value" for the whole network, but the
recieved mW from every reachable point in the network. So i think the
RSSI value for every network node (if i can print them out seperatly)
should do the job.
