ofRssiNoiseSamplingtoRssiPacketSampling code
I followed your commands but I encounter a problem that I cannot get over. More
specifically when I program Tx and Rx CM 5000 motes, connected via usb port, I
only find the recording RSSI values stored to the noise.txt file when I run the
TestSerial java app during the transmission process between motes. If I run the
java app after the transmission process, rssi recordings don’t pass from flash
(through serial port) to noise.txt. I attach the available files if you can
help me.
Kind Regards,
Tassos.
p.s. Tx_App is loaded to Tx mote and RSSI_Sampling is loaded to Rx mote.

sorry, rssi = msg.get_rssi()- 45 instead of rssi = printMsg.get_rssi()- 45;

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());
}

I am still stuck on how to convert RssiNoiseSampling app in order to
receive packets, store rssi to flash and after retrieve rssi from flash through
serial port. I want your help on how to break this app into two parts because I
want the motes record rssi (powered by batteries) and afterwards to connect Rx
mote with PC to print rssi to file (noise.txt). If anybody wants to cooperate I
can forward my transformed code.
Kind Regards,
Tassos.

I followed your guidance with printfUART but I am getting values with
unrecognizable format:
RSSI [6160292] LQI [17248]
RSSI [5373860] LQI [17248]
Is there any way to print the received RSSI by using TestSerial Java app
that is included in the RssiSampling folder?
Regards,
Tassos.

You must read the RSSI on received packets, you should be using instead:
event message_t* Receive.receive(message_t* bufPtr, void* payload,
uint8_t len) {
printfUART("RSSI [%d] LQI [%d]\n", (call
CC2420Packet.getRssi(bufPtr)-45), call CC2420Packet.getLqi(bufPtr));
You can wire CC2420Packet in your configuration file as:
components CC2420PacketC;
App.CC2420Packet -> CC2420PacketC;
Then in your module:
uses interface CC2420Packet;
Cheers,

Hi,
I am trying to transform HyungJune Lee code
(http://sing.stanford.edu/abbado/RssiSampling.tar) in order to print RSSI
readings from receiving packets instead of noise. I have included Receive and
CC2420Packet interfaces but I can’t bypass noise readings. Any ideas?
King Regards,
Tassos.
