Hi
I know there is a long discussion about location service using RSSI
value of CC2420 chip.
But when I tried to measure the RSSI values from received packets sent
every second, it seems very instable even in a range of less than 1 meter.

Thanks again for the quick reply!
I asked the original question because there seems to be a lot of

Hi.
I think I need to clarify my question.
I am using BaseStationCC2420 in order to retrieve packet data as well as
find out the delivery in PC through serial cable.
I combined BaseStationCC2420 with my program which needs saving of data
packets for a short time.
When I didn't save data packets
Well, yeah...But doesn't every platform also have the "raw" ADC implementation
which provides exactly the same interface, with a (well, to my low-level mind)
more straightforward connection to the external world? Admittedly there are
some 'tricks' that need to be performed to get, e.g., the micasb

Yes, however every platform has a DemoSensor, which allows demos (not
applications) to be written and compiled irregardless of the platform
(thus the prefix "Demo")
Assuming you already have .../tinyos-*/tools/java in your CLASSPATH,
there's probably nothing more you can do to help.
It seems that the no arg constructor Message() is private in
tools/java/net/tinyos/message/Message.java, and bean-like systems
usually use those constructors as the default insta
Hello,
I've been in the processing of converting the cricket platform file to
behave more like the mica2 to add mesh support. When I go to compile, I get
the following output:
mkdir -p build/cricket
compiling XMeshCountToLeds to a cricket binary, using binary components
ncc -o build/cricket/m
Did deeper into DemoSensor. First of course you have to figure out
which one and where it is...I don't (yet) have a tmote dev environment,
but for the Mica's it's in tos/sensorboards/micasb/DemoSensorC.nc

As far as I know moteIF is pretty much it in Java. You can use it
to connect directly to the serial port on the MIBs, etal. If you
want to slim things down, look at Packetizer.java where most of
the rubber meets the road. Also there are examples in C in the tools
tree, and C# seems to be possible
Actually, I found this

I'm not sure...
But why don't you define a timer to fire 5 seconds in the future?

Hi Everybody,
Does anybody have any code for T2, to read values from Light, Temperature or
Humidity Sensors? I 'm new to TinyOS, and I follow the tutorial, but only
has code for Voltage.
Thank you very much in advance

Hi guys,
I'm using a debian box, with netbeans gui, I've installed tinyos by
apt-get etc.
I get an error in netbeans:

Hi. I'm trying to find a way to write a command that can run a DC micromotor
for 5 seconds before setting the PWM signal to low and stopping the motor. I
know I should use the Timer command, but how do I incorporate the length of

Do you know any method or module can be used to tell whether the radio

A RSSIADC.dataready event is used in tinyos MAC modules, so that I cannot build

Even I can build the event, I cannot make this event to be
