I've been collecting data with TelosB motes for the past few days, and when
I started to analyse the data, I found some weird points where calling
LocalTime.get() would return values about ~1 earlier.
Has anybody experienced this before, and is this an expected behaviour?
I've been relying on i
hi I'm a student and I work on wns, I'm implementing a Mac protocol and I have
some unclear concepts, help plz!
1)What is CC2420_TIME_ACK_TURNAROUND? and what is the difference between it and
CC2420_ACK_WAIT_DELAY?
2)In my protocol I want to use the preamble, I read in the cc2420 datasheet
that
Am trying to interface Telosb mote with ADXL345 accelerometer sensor. Am
using the sample program available from

No clue, I don't know what modifications you have made... around those
lines there should be the components and wirings of the interruptions,
did you define it? (see tos/platforms/z1/chips/adxl345)
A more updated test example application for the ADXL345 accelerometer is
already merged in TinyOS t
Dear all,
I downloaded from sourceforge all the minitasks\02\vu\ CVS folder to try the
AcousticLocalization application of ISIS Vanderbilt University. I have put the
folder vu in :
cygwin\opt\tinyos-1.x\contrib\vu\
and I have set the environment variable VUTOS as explained in the ReadMe file

Giacomo:
The code in contrib/vu/apps/AcousticLocalization does compile for
mica2. If you need to get it work on another platform, you'll have to
figure how the makefiles need to be adapted to include the required
interfaces.
Please note that this code was written 10 years ago, that is, it
predate
Hi,
I am a bit confuse. I am not really clear how a call to
CtpInfo.setNeighborCongested(from, congested) can set the neighbor as
congested (in the BeaconReceive.receive() event in CtpRoutingEngineP)?,
because I found that a call to CtpRoutingPacket.getOption(msg, CTP_OPT_ECN)
returns FALSE, there
Dear all,
I am using the AcousticLocalization app from the Vanderbilt University.
I am trying to run the java app AcousticLocalization as is described in the
README.txt file in:

To get to the actual TOS release for the nescc builds under T1,
I think what you need is something like this in your environment
(on Windows):
# Set main pointers used by TOS build system to find files
# TOSROOT is for external programs, TOSDIR for makefiles

Hello,
hardware-acknowledgements have been reported to work on real devices
(AFAIK), but while trying to simulate a TOS application using HWACK with
LPL, i stumbled upon following behaviour:
Phase A: The driver puts the radio into RX_AACK_ON mode. All is fine
until
Phase B: A transmission gets sta
Hi Markus,
On page 89 of the datasheet there is a workaround that shows that you
can switch between TRX_CMD=TX_START the to TRX_CMD=RX_ON and then to
TRX_CMD=TX_ARET_ON. So even in the manual they use this (at lease in
one of the published workarounds of an errata). I do not know how
slower the "p
Hi Miklos,
thanks for pointing this out. I did not simulate errata and ignored them
therefore - Until now.
I will have to think about how i can handle this very special behaviour
in my simulation. Silicon bugs suck.
Regards,
Markus

I have seen many silicon bugs (both in the RF230 and SI4432) and bad
documentation. Miklos
