Hi!

Sorry, I misunderstood the meaning of RSSI values. So if I'm bringing 1 mote far away and it must increase it's transmission power to maximum, than after some distance I can't distinguish any more between distance changes, however the packets are well transmitting. It's sad that it becomes so early.

P.S. Sorry, if my answers are still being posted as new thread.
I click on answer/answer all button in the web interface of my mail server,
and I'm not changing the topic, but something goes wrong :(
Maybe any advices?
