Hi,
Take a look at the tinyos folder, this is basic manip :
/opt/tinyos-2.1.0/apps/tutorials/RssiDemo.
For converting to [dBm] value obtained slightly modify the java code
(RssiDemo) as follow:
public void messageReceived(int to, Message message) {
RssiMsg msg = (RssiMsg) message;
//int source = message.getSerialPacket().get_header_src();
//System.out.println("Rssi Message received from node " + source +
// ": Rssi = " + msg.get_rssi());
int source = message.getSerialPacket().get_header_src(), rssi;
rssi = printMsg.get_rssi()- 45;
System.out.println("Rssi Message received from node " + source +
": Rssi = " + rssi());
}
