All this happened after the installation of T2 (or upgrading, without
touching T1)..i don't know how i might have messed up the access to that
directory. Anyway, is there any possibility to know what to modify in
/usr/local/avr ?
i don't know exactly how this directory has to be..
thanks very
Hi I was wondering if it possible to edit a .target/.extra or similar file to get ncc to search appDir e.g.(blinkk)/sim directory for tossim specific compenents.I know that it does this in the micaz platform directory, but i have no idea what is telling tossim to search sim specific directorys.if
Hi Michael,
I've found the problem right in usr/local folder.
It's strange but the sub-folders avr, lib, include, info, share and bin
in tinyos-1.x (from a pc which runs only tinyos-1.x) are different than
the tinyos-2.x's ones (for example avr folder is empty here).
So to switch correctly from
Hi Nuwan,
You can see some conversions in the file xconvert.c in
opt\tinyos-1.x\contrib\xbow\tools\src\xlisten and in the file mts300.c in
opt\tinyos-1.x\contrib\xbow\tools\src\xlisten\boards.
I hope this help you.
Andrés.

Hi,I have additional information regarding the problem with the communication from pc to node. If I use transparent base on two nodes and I am sending a message over uart to node a with the address of nodeb it works. But if I want to send a message over uart to nodea, how can I do that? I
Hi Antonio,
There should be a soundrecorder.txt file in the folder. Looking at this, it
says you need a tool called Txt2Wav:
isis.nest.util.Txt2Wav
I've not got this in my CVS tree which I got from Sourceforge fairly recently.
You may be lucky and find it in yours. If not, all I can suggest
Try getting some metal (NOT vynal) screen at a home improvement store and put
the sensor in that. Connect the screen to a ground (a water pipe is good).
That will give you a Faraday cage. Alter it with windows in the sides or
grounding/ungrounding to get the desired signal strength.
It's still
In 802.15.4, the frame format is defined as:| PHY preamble | SFD | length | MAC_header | MAC_payload | MAC_footer
Therefore the previous three (or two) fieldsseem toform the PHY header.
But in tinyos 2.x there is:
async command error_t PhySend.send(message_t* msg, uint8_t len) {
... //
I like to think of it as a retraction period...
I got similar results on micaz and 2, though driven
by a host PC rather than another mote:

I don't know where the time goes, although using ACKs
may help in some cases. It would be interesting to
Hello,
Does anyone know the resolution of SysTime.getTime32() ? Is this in
microseconds? It seems to be a 7 digit number. Any help would be
appreciated.
Thanks,

I dunno why T2 would empty the AVR dir, nor if it works
if one exists. Have you tried switching back? Maybe it
was an install glitch.

It is packet loss at the TOSBase where the serial port operating at 56kbps cannot keep up with the radio operating up to 250kbps. You could try chaning the UART baudrate:

huh, I hadn't considered that...good point. However...
at ~40 bytes (320 bits) per message, 100 messages is

Also I had the same-only-worse problem on the mica2,

Thanks for your response. I have tried out pthread.h with other C

What does that line of pthread.h say?

Dear Sir,Thanks for your advice but I got another alternative. I am using Aluminium Foil to cover the antenna to reduce the signal strength and it worked to some extent. I think if we able to create a cover over telos motes antenna of certain thickness then we can reduce it length accordingly. As
Also consider the fact that the TOSBase has to interleave the reception of the packet and the transmission on the serial port. This reduces your transmission rate further on the serial port. I had done experiments earlier to measure this and found about 21 Kbps was the max rate I could achieve
If you send a description of your platform and the sequence that

Thanks for your help... it worked... but now I have another problem...

Om,
Thanks! This fixes make pc. I'm able to compile as well as run
simulations with this. The other programs I had tried out, were using
the same pthread.h as TOSSIM. They are working even with the modified
pthread.h. So it seems that the problem must be with something TinyOS is
doing.
Thanks,
Hi,
I have a component (C) that repeatedly starts a timer in ONE_SHOT mode
and each timer the timer fires, a message is sent and the timer is
restarted in ONE_SHOT mode. Finally, the main component (A) calls
C.stop ( ), which in turn stops the timer. I am using TOSSIM for
testing and the
Hello Eveybody,Is there any interrupt or pin on CC2420 radio (for telos tmotes) which goes high when a message is received? Can I access the state of that interrupt with a command? Actually, I need to add a time-stamp when a message has been received, to indicate the reception time.
