Hello all.
We are currently working on a thesis project which involves implementing two
routing protocols in TinyOS 2, for comparison in a WSN setting.
We have been through all the tutorials and support-pages, but we still have

We are having a problem compiling the TestMCU application (or any other for

We have checked out the latest revision of contrib/cedt from CVS and done a
"make install" according to the instructions. But when trying to
Hi,
I am currently trying to set up a WSN using tinyos-2.x. I have Chipcon's
CC2420DBK with me, it has an onboard temperature sensor LM61 attached to
it with atmega128 processor. I am trying to read the temperature values
from this sensor, I am constantly getting 0x3ff as my data in the raw

Hello everybody,
I need assistance with avrdude.
I work with TinyOS 2.0.2 on Ubuntu 8.04. Avrdude is installed form the

Hi everybody,
I use TinyOS 1.1.10.I get RSSI(unit_16) in Hex as
0x0015.With reference to previous mails on this list.I use the following
formula to get the following values.
Vrssi = (3 * RSSI_VAL)/1024;
RSSI in dBm = -50*Vrssi -45.5 ;
what should we substitute for RSSI_VAL
Hi,
if I remember right Port 10001 is for programming only. Try port 10002.

Hi,
When I was trying to program my telosb motes on an Intel Mac, I got
the following error:

Yes, it's because you are using a multimeter. With a 1 ohm resistor, you
will be reading about .02 volts difference. You should read the voltage
across the resistor, not measure on both sides and take
the difference. Most multimeters do some autoscaling.
You may have more success using the am

a.)The environment variables are set up correctly (TOSDIR and MAKERULES in
particular). If you have some environment variables left over from some older

i also find a strange problem .

0x3FF is the maximum value you can get from the 10 bit ADC.
So either you have _way_ overheated your board, in one way
or another, or you are not reading it correctly. Put the board
in the freezer or try a different ADC channel to see what you get.

RSSI_VAL == the ADC reading == 0x0015 in this example.
But that gives -95dBm which seems like a noise value...

Yes, in fact, this is what I'm implementing on the CC1100 and CC2500 radio
stacks. The trick is getting the transmit branch of the radio stack to hold
off for awhile if a packet was recently received. This allows one node to
completely dominate the channel while it sends back-to-back packets with
Hello Eric ,
Thank you for your reply. You mentioned - " *You should read the voltage
across the resistor, not measure on both sides and take
the difference." *I did not quite understand this line. Where exactly
should I place the resistor ,
Is something wrong with my arrangement - one side of
All the current has to go through the resistor, it sounds like you
have it in the right place.
I was addressing this statement: "The readings are 1.5V which is the
battery voltage."
The voltage across the resistor should be very small, or you have a
problem with
your resistor.

Have you disconnected the mote from the battery? The correct arrangement is
as follows:
Let the
battery (power supply) terminals be "A" and "B"
resistor terminals be "C" and "D"
mote terminals be "E" and "F".
Usually the battery and the mote would be connected: i.e., "A" is connected
to "E" and "

Thanks ,
That sounds pretty neat. I will try that .

I can confirm this. My CC1000-based motes work fine with the 2.0.2
release but crash with the latest cvs. I run a modified BlinkToRadio
to test, with one node only transmitting and the other node only
receiving. The transmitting node works ok. The receiving node seems
to crash. As a test, I turn on
Hi
I have some question regarding how to measure power consumption on sensor
motes.
1. Is current is the best way to measure power consumption?
2. Can someone recommend me some tools to do it? It seems that multi-meter
can not achieve high accuracy.
3. Does someone try to measure current consumpt
dear all
does tossim work normally in tinyos-2.x just like in tiny-1.x?
could somebody give me some advice about how to use tossim in tinyos-2.x?
thanks!

No. It does not work the same (although it uses similar concepts).
For example, there is no TinyViz and the primary interface is Python
scripting (in TOS 1.x Jython was an add-on).
Start with the TOSSIM T2 overview: http://docs.tinyos.net/index.php/TOSSIM
