Hi Om,
Motes send a packet every 10 minutes.
What should the low power listening duty cycle or sleep interval be for
that rate? Any idea what the current draw should be in low power state?
I switched from using duty cycle instruction to sleep interval yesterday
and, although the current draw
Hi,
That question is probably of more general interest. I'm sorry if I
bother you here. I vaguely remember that somebody once said that CTP
does not support LPL, so I have a couple of questions:
Could you briefly explain what you did to get low-power listening to
work? Did you just have to
Hi,
From what I've understood form CTP, yes, Receive.receive is in the Root
node only, as this event only happens in the root node. Snoop I haven't
used, but I understand it is used in the nodes.
Remember that in the root node you have to set the node as root, usually

Hello,
Is there someone who used MIRACL library in a tinyOS application?
How did you include this library in your code?
Please, I am waiting for a response

Hello Omprakash,
As a remainder i used MultihopOscilloscope application.i have three nodes
and data portion of the messages (readings[]) is filled with node id's as
0,1 or 2.
AM_OSCILLOSCOPE = 0x93
AM_CTP_DEBUG = 0x72 (followed with CollectionDebugMsg structure... When i
reset any remote node,
I'm supplying my mote with DC voltage source, to be able to control the voltage.
I've noticed that when the voltage or = 2 V the mote does not work.
My question is, is this means if i used a battery with 3.3 V the mote will work
from 3.3 - 2 v and then will be shutdown, and can not use the
The mote will not work if the voltage is that low. Notice, however,
that the voltage of the battery is not decreasing linearly with time
when the battery is discharging. ( See charts for low current draws at
http://www.powerstream.com/AA-tests.htm )
the mote will work from 3.3 - 2 v and then
Somewhere, something, probably uses a Timer.start() to set
a sample period, and those defines _might_ have something
to do with it. I'd search for them in the code and see what
they are used for. It might be that APP_RATE is the thing
you want and that you can set it in your main program file.
As
If your meter is indeed measuring Amps -- or more appropriately milli-Amps --
the serial connection you describe should work. You may have the meter
set to measure volts, in which case it's impedance will be very high
and it will act more like an open circuit.

The mote
Hi All,
I have three TelosB motes. One mote connected to PC, acts as a Base Station.
Other two motes sends the messages (normal TOS header + one byte field for
the TOS_LOCAL_ADDRESS) to base station. When base station receive the
messages it displays on the PC (used Listen.java for this). When i
You might try using ListenRaw to see the whole byte stream
and look at the checksums. I forget if the basestation code
verifies the checksum. I know the Listen code rejects messages
that fail the checksum, so it looks like you are getting good
messages. Maybe try a longer, predictable, data packet
Hello everyone,
I just started learning TinyOS and I'm having a problem compiling using *make
micaz sim*.
Compiling for Micaz and Telosb works.
This is the output from *make micaz sim*:

Good Night guys,
Im studying middlewares, and Topology Control Protocols and i want to
implement some ideas in TinyOS. I need to meausure Energy Use,
Bandwith/Throughput and Energy Remaining.
Looking through the TinyOS archive i discovered that its really hard to
meausure Energy Remaining , and
hello,
i want to work on tiny-os. but i have problem in installation .i am trying
to install on fedora core 10.Is it because of that?
Please help me in this regard.

Dear All,
I have encountered the following problems.
Once I typed in $java net.tinyos.tools.Listen -comm ser...@com1:micaz
my cygwin got stucked, only one message there:
ser...@com1:57600:resynchronising, then no responses any more
Then I tried another test, after downloaded testserial
