Hi Mohammad,
After reading your original description of the problem, I think that an
intermediate node (e.g. the basestation) does not realize that the nodes
have been reset. I think that XMesh uses sequence numbers in their
packets. After a node has been reset, maybe it starts over again with
Hi Joe,
Can you be a bit more specific? What file do you want to manipulate?
Where is the file located (on a PC or a sensor node)? With what language
would you like to do it?
Cheers,
Urs

Hi,
I wanted to know if anyone here who has worked on Crossbow's micaz motes
have any idea if there is an arrangement for acknowledgement of sent packets
at the link layer. This will help me decide whether I need to write a
function that checks for acknowledgements (implicit or explicit) or j
Thanks for the reply, I did figure it out after a while. I misread the code
initially. But for some reason the mote was reporting that the supply
voltage was too low and did not want to reboot. I thought that this was not
possible as the mote was plugged into a USB port. Until I physically

Hi,
during my work with the Mica2 motes I used the "Avrora - The AVR Simulation and
Analysis Framework" to test my programs without installing them on the motes.
It was a nice thing.
Now I work with the IRIS-motes. Thus, I want to know if anyone of you have
experiences with "Avrora - The AVR Si

Hi all.
I was wondering is there a way to write on a file like use fopen() and
fwrite()?
Or is there a way to redirect the printf on a file?
Finally is there a way to get the current time?
I use tinyos.2.1.0 and telosb

Can you send me your source code, along with your wrapper. I will try
and track down the problem.

Motes don't have ethernet ports, so no IP addrs.
You can use a SerialForwarder program on a host PC
to "convert" messages from the USB port to an i'net
port, in which case the IP addr will be that of the
host computer with that port number appended.

micaz's have both hardware and software level acks
which can be enabled in your code. When enabled you
get a flag in the message.ack field in sendDone().
There is no automatic retry or anything fancy though.
Search this list for information about them.

pow() probably operates on doubles. I imagine that there is a
float version for the motes, maybe powf(). Look at the math.h
header for your platform, in the include directories for the
specific compiler you are using.

Hi,
In TinyOS implementtion, what is the difference between Carrier Sense and
Clear Channel Assessment? Both are said to be used to decide whether the
channel is idle or not..
Thanks,

Kevin,
So, I think it may not be a tosthreads problem, after all. As long as I
call configure for each call to getData() then everything works fine. From
the documentation, I got the impression that you could call getData multiple
times after configuring the channel. The behavior of returning S
Thanks Urs for your reply,
I don't think if this would be the case, because first of all if this
problem was because of XMesh sequence number, this would happen for every
mote, while this problem just happened for 7 or 8 motes out of 10. The
second point is that after this problem happens to a mot
I just noticed that somewhere between Tinyos 2.0 and Tinyos 2.1, baud rates
above 38400 stopped working on the tinynode. I can get around it easy
enough by using low baud rates, but I just thought I would report the
problem.
When the rate is set too high, it gives a lot of "bad_packet" errors.

I'm wondering why the ZigBee mote can receive TinyOS structured packets?

I am writing to ask your help on the DAC functionality. I am using TinyOS
2.1.0 on Tinynode.
I have read through many information, including the MSP430 User's Guide,
README text in MSP430/adc12 folder,TinyOS programming, TEP on Resource
Arbitration, Boot Sequence and Schedulers and Tasks. I have s
Thank you all very much. I will try during these days.
Our ZigBee mote use tinyos8051wg (http://www.tinyos8051wg.net).
It doesn't implement active messages yet. It just communicates with
the simple packet. Hence I think it wouldn't check packet format at
lower layer when receiving packets.

Since this is very time critical, I would set the port values
directly. Port A2 is the red led, that's a good point to start with.
See chapter 13 in the atmega1281 datasheet.

Hi all,
I have to send some x bytes of data every y milliseconds to the mote. The
java program in TestSerial (tests/TestSerial) works good but I want the c
program sdk/c/sf/serialsend.c to do the same task. Unfortunately when I make
the serialsend.c send some data, the mote does not receive it.
