I figured out the basic idea in CountSleepRadio application is to start and
stop the CommStdControl() or CommControl() at appropriate times, say 2 seconds.
And this application works.
I have one basic same question and problem, which I was having in implementing
the alternate application,
I am using Tinyos-1.x with a MicaZ mote and trying to do some work at high
rates. But when I use the TimerC, it seems that the timer couldn't work when
the interval is below 4 milli second. It means that when I use codes as
follows,
command result_t StdControl.start() {
Hello all,
I've been writing code to send messages using the Sensornet Protocol.
I'm struggling with sending a large buffer (don't want to use Spram)
of data from a mote to matlab. Anyway, I send chunks of the large data
buffer, residing on the mote, and combine the chunks in matlab to
rebuild
There are timing problems when a timer is below 4 ms - I
believe it was due to the microcontroller not being able
to keep up with executing code that quickly. If you look
at the code that gets executed when you call
Timer.start(..), one of the first tests is to make sure
you're not trying to
Ok, I'm Beginning to See the Light here...
I was using TOS1.7 to make my robots on mica2's and a 1ms interval
setting worked just great. But then I tried the code on micaz
(and had to upgrade to 1.10 to do so) and there indeedy is the
if( ... interval = 2 ) no-go;
So I gave up and stuck like
Quick answer: If you need timing resolution on the order of ones of
milliseconds, you should be using a hardware timer in TOS1 or an Alarm in
TOS2. Also note, for Telos/Tmote the 3 check is in 32khz units, not 1khz
units.
Response to the odd comment: Atomic sections cannot prevent the issue
to whom it may concern,
I am a graduate researher at The City College of New York of The City
University of New York(Cuny).I would like to actuate an external sensor using
the sloid state relays of the mda300ca sensor board. I would like to know how
to program the mote to trigger the
Hi list,
I've got three questions concerning TinyOS 1.1.15:
1.) Clock and Time: Is there a simple way to obtain some sort of time (in ms)?
I does not matter, if it is the time since boot or a global time. It's just
some relative time in ms I need and does not have to be exact, i.e. it does
I suppose it's all moot at this point as (it sounds like) T2 uses
some different approaches. But...I remember distinctly using T1.7
on mica2 and timing my ADC conversions vs 1ms TimerC ticks quite
solidly with a logic analyzer. And that was with a fair amount of
calculation taking place in each
The architecture described in TOSSIM: Accurate and Scalable Simulation of
Entire TinyOS Applications is also valid for Tossim in TinyOS 2.0?
Thanks a lot for any help.
Salvo

I see it now, you are right, it was a bug in my code causing it to send the
same message over and over again.
Thanks :)

Hi all,
I'd like to know how to calculate the values of lqi in metadata header of
CC2420 in tinyos 2.0. Is it relevant to the value of rssi? I got some values
listed as follows from experiments:
rssi 3A 3E 3F 40
lqiDF D9 D7 CE
Thanks in advance

Hi,
Does anyone know if there is a way to use the dbg() statements to have
TOSSIM run arbitrary commands in python?
