Funny -- when I saw the original message I tested the repository myself and was 
able to access it with no problem, so assumed it was a momentary glitch. I 
admittedly tried only from a machine inside Stanford, but given the error 
message didn't think this should have changed anything. Sorry for the 
disruption.

Eric -- your message on the 4th went into my -help folder (because of the 
subject line) which is why I didn't see it immediately.

[Tinyos-help] Problems with SPI

[Prasanna Karthik V]

hi,
Here is an experiment that i performed to compare the idle voltages i
get at pins SO,SI and SCLK.

telosb(tmote-sky) platform {SO=2.4V, SI=2.4V, SCLK = 2.4V}

I attached an external radio to the original telosb platform (disabled the
radio that comes with the tmote-sky) and tried measuring the same.

New platform {SO=2.4V, SI=2.4V, SCLK = 0.7V}

As SCLK is just an input to the radios, attaching a different radio to the
SPI pins should not make any difference to SCLK.


Any idea why this happens?

P.S: In the MotePlatformC.nc file, the initial values of the pins(S),SI
and SCLK) are specified to be the same in both platforms.

[Tinyos-help] Urgent Help Required about TOSSIM

[Saif Ahmad]

Dear All,

I am a newbie to the TOSSIM and am working on a term project that involves
simulating the CTP protocol on TOSSIM. Can somebody please provide a
step-by-step procedure on how I should go about accomplishing my task. I
have already installed TOSSIM on my laptop and am able to compile it for
Blink but how to go about running CTP is my real problem. I have also gone
through the TOSSIM tutorial.

Any quick assistance regarding the above matter is highly appreciated.

Thank You

[Tinyos-help] cc2420 security questions

[Viktor Zsoldos]

Hi,

I'm trying to use the CC2420 security features 
(http://docs.tinyos.net/index.php/CC2420_Security_Tutorial), and have some 
questions.

- I've installed the BaseStation from apps/tests/cc2420/TestSecurity, and 
trying to read the secured traffic with net.tinyos.tools.Listen, but only 
ordinary headers are showing (dst, src, len, gID, hID), I can't see any CC2420 
or security related headers. They must be there, since I can read out 
e.g. the frameCounter field from security_header_t with a mote, and put the 
value to LEDs. What's the trick?
- With CBC-MAC mode if I change the key value of the sender mote, the receiver 
will still happily accept the packet with the wrong MAC. Do I have to 
generate the MAC at the receiver manually to check if it equals to the received 
one?

Thanks for your help!

Viktor

Re: [Tinyos-help] Boadcasting packets once at a time!!

[Sergio Valcarcel]

Regarding the noise floor, you can directly look at the "receiver
sensitivity" on the radio specifications. That is the minimum level
that you will be able to get. I think that is all, unless you mean
about interferences...
But anyway, I would say that you can not measure interference from
other service since I guess the rssi measurement is computed from some
pilot bits of the packet.

Cheers,
Sergio

What you should do is figure out how to send single packets,   This is done
using various Send interfaces.  This is split phase so will be signalled by
SendDone.   Then you can send out the next packet.   Start with the
tutorials, then take a look at real code that does something similar to what
you are trying to do.   A good programmer copies and makes things better.

No clue on this end.  Haven't messed with that so haven't looked at it.

What I would do is start with the chip documentation and figure out whether
the chip can provide this information when not actively receiving a packet.
 Then work up through the driver to figure out a good way to present this
information in a platform independent fashion.

You want to look at how the packets are layed out on each end.  Basically
you need to dig into what is happening and figure it out.

[Tinyos-help] Help me to Run "Surge" application in Micaz

[Nazmul Hossain]

I was trying to run the "Surge" application but was not successful. Using 
MIB520 programming board I programmed surge program onto two micaz motes. To 
program these two micaz motes I used the following commands.

make micaz install.0 mib510,/dev/ttyS3
make micaz install.1 mib510,/dev/ttyS3

Then according to the instruction, I tried to run java application by keeping 
the mode of ID 0 at programming board and other mote of ID 1 far from the board 
(uses batteries in this mote) and using the command

java net.tinyos.net.tinyos.surge.MainClass 

but it asks for groupID. I found groupID "0x7d" in the 
"opt\tinyos1.x\tools\make\Makedefaults" file. 

But if I use this groupID it gives me error in java. 

Can anyone please tell me what I am doing wrong? or how can I run it correctly.
 
Thanks.

[Tinyos-help] Floating point communication between telosb motes

[Mayank Gupta]

Hello everybody,

I am trying to develop an application that sends floating point number
between two telosb motes. I referred to BlinkToRadio application and
saw that it could send integer numbers between motes. I tried to use
nx_float in the nx_struct message structure but it didn't work . I
also tried using normal float. Since communication is between two
telosb motes I do not think there could be platform problems. But i
was not able to send data correctly. Can someone guide me in the right
direction for the same.

Thanking you in anticipation.

Re: [Tinyos-help] Wireless Sensor Networks Simulation

[Michael Schippling]

GA == Genetic Algorithm

Pareto (wave) front == In game theory a Pareto move is one that
gives one or more players a higher payoff without reducing the
payoff to the others. A Pareto optimum is where all the players
are at a point where none can increase their benefit without
reducing that of another. This may (is probably) not a stable
Nash equilibrium point...the Prisoner's Dilemma is a good
example.

In TOS a list of apparently random (phone) numbers is par
for the course...so probably a Nash.

I am not much of an optimizer myself.

Re: [Tinyos-help] Injecting packets for tiny OS 2

[Sergio Valcarcel]

Hi Lyubomir,
Please, could you explain further what you mean with sending more than
one packet at a time? I am sure to be missing something, otherwise
could it be as simple as to make a for-loop?

For setting the power I am only familiar with the CC2420 radio. In
such a case you only have to load the right module.

In your config file...
// Receiver calibration
typedef nx_struct SerialRxMsg {
        nx_uint8_t id;
        nx_uint8_t rssi;
} SerialRxMsg;


In your module...
module CalTxC{
        uses {
                        interface SplitControl as RadioSplitControl;
                        interface SplitControl as SerialSplitControl;
                        interface CC2420Packet as RadioPacket;
                         etc...
        }

        implementation {
        RadioMsg * pointerRadio;
        SerialTxMsg * pointerSerial;
        event void RadioSplitControl.startDone(error_t error){
                if (error != SUCCESS) {
                        call Leds.set(6);
                        call RadioSplitControl.start();
                }
                else {
                        call SerialSplitControl.start();
                }
        }
        event void SerialSplitControl.startDone(error_t error){
                if (error != SUCCESS) {
                        call Leds.set(7);
                        call SerialSplitControl.start();
                }
                else {
                        call Leds.set(0);
                        pointerRadio = call
RadioAMSend.getPayload(&pkt, (uint8_t) NULL);
                        call Timer.startPeriodic(PERIOD_0);
                }
        }
         event message_t * SerialReceive.receive(message_t *msg, void
*payload, uint8_t len){
                call Leds.set(7);
                pointerRadio = (RadioMsg*) payload;
                call RadioPacket.setPower(&pkt ,pointerSerial->rssi);
                return msg;
        }
}

In your configuration...
implementation {
        components ActiveMessageC;
        components new AMSenderC (AM_RADIOMSG);
        components CC2420PacketC;

        components SerialActiveMessageC;
        components new SerialAMReceiverC (AM_SERIALTXMSG);
        ... etc 
}
I assume you know the rest :-)
Cheers!!

Re: [Tinyos-help] help UART

[Eric Decker]

There is a packetizing protocol that is used for communications on the
serial line between the mote and the PC.

You have to have that there for the communications to succeed.   You should
work through the tutorials to understand better what is involved there.  You
will also have to do your homework and try to understand how this works
rather then saying please help me.

Check out the serial forwarder.   It already implements the protocol for
communicating.   You should be able to figure out what is needed from
examining how that works.

[Tinyos-help] help UART

[Edoardo Patti]

Hi, I try to develop an application in C# (under windows) to comunicate with
the root-node (telosB) through the serial port. I can read the messages sent
from root-node to PC, but when I try to send some messages from my PC to the
root-node, it does not received the message.

On the root-node runs the antitheft application.
The message, sent from PC, is a byte array.
The PC-UART configuration, to open the communication,  is:

   - baudrate = 115200,
   - dataBits = 8,
   - parity = none,
   - stopBit = one,
   - RTSenable = true


Please help me.
Thanks in advance

I'm not understanding what you are trying to do.   Can you please try again
and be more succinct.

Are you trying to send a packet stream (one packet, then another packet,
then an another) to the broadcast address?

Work through the tutorials that help you understand how to use the
networking interfaces.   That will probably give
you the insight needed to do what you want.

[Tinyos-help] Boadcasting packets once at a time!!

[Lyubomir Ivanov]

 
Hello, 


Is someone can tell me how to send a stream of packets once at a time, using 
broadcast. Am I supposed to create some special code, or just small 
modification in the message type will be enough? I am using tiny os 2
