Hi all, I'm doing some experiments to measure the Rssi value of the telosb motes in TinyOS. I did this by sending blank packet to base station and calling the CC2420Packet.getRssi(msg) command in the receive() method of Base Station and storing the returned value in the packet. Then I get the value in raw packet with java Listen tool. I measured Rssi from different distances and the value I get is either around 0 or 65500.
Am I measuring Rssi correctly in this way? Is the raw value I get from the packets the real Rssi value? I know the value could be influenced by the environment, but could it also be influenced by some default packets (although I didn't set anything on sender mote, just sending some blank packets) ? Anyway, what I want to verify is whether the Rssi value of a sensor mote measured by a Base Station from different distance stable enough to distinguish it from others? Appreciate if you have any comments or ideas. Thanks in advance! -Sean
