Hi,
Sorry for the spamming. In fact it works alright. I have revisited the
tutorial, updated my script (I wasn't using this "heavy-meyer" and noise
model before) and now it works fine.. Maybe there were some changes in
TOSSIM since 2.0.0.
Best regards,
Alban

Although the "LOW_POWER_LISTENING" compiler flag will add in the low power
listening layer into the radio stack, some other functionality needs to
exist to tell it what to do.
Currently, CTP does not instruct the radio stack to use low power listening.
To make it happen, right now developers have
Hi all,
I use mica2,tinyos 1.1.10.I receive the following RSSI values
in Hex for Max and Min Transmitter power :
00 4f(Tx power =5dBm) and 01 31(Tx power=-20dBm)
When 2's complement is taken we have:-79 and -305
To these values,-45 should be added.So, we have -124 and -350 respectiv

I'm trying to run some power measurements of motes running CTP

Right. But I think this is that memory problem I ran into. Cutting the trace
down just to identify if its the same problem.

Hi,
I am trying to read rssi values for my application (on basestation). The
algorithm I use calculates ambient noise by reading the rssi value just
after the packet is received at basestation. This seems to work fine on
telosb, but on micaz 3-4/10 times I get a strange reading of -135 dBm. (at
Hi all,
I'm using Crossbow's MDA320 as my sensor and trying to modify the
code"XMDA320" with "SenseToLeds" code so this code can send signals to
toggle my LED at the receiver mote. Then the receiver mote will receive the
toggling signal by "RfmToLeds". But when I'm compiling it, I don't know

That brings up another question. I believe TOSSIM stores the noise trace
for each node even after the noise model is generated. This is because
you can use sim_real_noise(...) to recall the noise trace later.
However, (maybe I am missing something here) is anyone actually using
sim_real_noise(.

Let me know how it goes.
If you make the trace 100 lines long, it's pretty meaningless.

Hi,
I have been trying to implement the in-line AES encryption/decryption on
Tmote using Tinyos 1.x. I managed to use the stand-alone encyption. However,
according to the notes from Kun Sun, I have to perform the following:

Hi
I wish to sample a 2-axes sensor that is mapped to channels 6 and 7 of the

am not sure how exactly I should use it. In particular

Hi all,
Is there any ongoing work or research on QoS support in TinyOS? Or is there
any QoS routing protocols implemented on TOS?
I would like to know if there is anything implemented on TOS that is related
to QoS support.
Thanks a lot.

I am running the Cygwin installation, and am having the same problem with
the TestSerial tutorial. I dug into the scripts a little, and it appears to
be looking for .dll files in the /usr/lib/tinyos directory that match
'*-32.dll', but there are no files in that directory that meet that
criteria.

I have the last cvs update of T2 and Python 2.5 on Ubuntu 7.10.

The execution of the test seems to never happen..

Can SysTime be used from TOSSIM? Is there any way to use the SysTime for

I've also seen issues with incorrect timestamps. Like David says, a
problem may be how a packet can be identified as dropped (by the
address recognition), because currently this is done by calculating
the time between rising and falling SFD (which may not be a 100%
reliable approach). I have two ad
Hello,
yes I have it for my compiler under
"C:\jennic\cygwin\ba-elf\libexec\gcc\ba-elf\4.1.2"
and I can compile Null for msp and avr normaly.
and with this compiler I can copile jennic programs normaly
so I want to understand what's wrong ? are the libraries used the correct ones ?
Thanks
