Hi Michael Thanks for your reply.
I was able to solve my problem but don't know exactly what was wrong.
Anyways now I am getting my values but really confused with the numbers I am
getting.
They don't seem to be right. I am going to attach you a copy of my code and
hopefully u can see if I
Dear all,
We got a new MICA2 system with an MTS300 sensors card and all efforts to
activate the sensors under TinyOS 2.0 failed.
We are able to activate communication betwenn several sensors BUT activating
the light, temperature or microphone have failed.
Any help or directing us to a working
Hello,
I have two versions senarios which lead to the same results but don't:
V1: A mote emits a packet every 2 seconds - 2 other motes right beside
it, which can reach the base station programmed with TOS_base both
receive the packet and send (sequence numbers are used) i.e. every 2
Thanks for your answers. So, an existing AVR toolchain seems to be a
problem indeed. In that case, is there perhaps a temporal solution to my
problem? Or are there many references to the current location? Or are
there only some general configuration files that have to be changed? I
can do it for

Hi,
I am evaluating two routing algorithms in tinyOS. The purpose of the algorithm
is to evaluate lifetime of the network. Can any help me how we can estimate
the residual energy of a node in TinyOS? I am using tmotes.

Hi,
as far as I understood from the code porting guide (related to Tahir
Azim's experience) and from this meeting note (http://
mail.millennium.berkeley.edu/pipermail/net2-wg/2007/000647.html), a
BVR port to TinyOS-2.x is in the works. Needing point to point
communication in my T2 apps, I
Thank you, Phillip, for your kind help!
Some things are now clearer (thanks to the more commented code of the
MultihopOscilloscope) , while others still remain confusing.

reading the CTP 123 TEP. i believe it's done some sort

I am trying to activate My mts300 Sensor Board for the Mica2 motes,

Hi all,
I have 2 questions about the mate (ASVM framework):
Does the generated application specific virtual machines support multiple
running applications?
Does the generated ASVM could be updated during runtime or just the
application(s) could be?
Thanks

Thanks for the help it worked, one question though:
With the id's now implemented I am unware if a packet has been
recieved (which I guess is the case :-D). BUT i'd still like for the
motes to forward packets, even if its not for them.

Assuming that the 'dot works like the mica2,z you shouldn't need
to read the ADC directly, but rather just look at the TOS_Msg.strength
field in the receive() function.
The dot is almost a Mica2. Not 100%-it's more like a mini Mica2.

please tell me if we can use two sensor value like photo and temperature

You can't sample some of the values at exactly the same time, but you can
send anything you can fit into 29 bytes.

Sorry I'm a T1/mica2 kinda guy so I'm not much more help.
I assume that the Telos do not transmit directly to a host
but have some intermediary, or base-station. That would be
on place to store samples. I don't know if they have EEPROM
like the mica's though. In T1 there are modules that access
Just to keep a record of my blathering I'm cc'ing the help list...
If you want to measure message send/receive time on the motes
directly you will need some way to synchronize their clocks.
This isn't easy. I just posted a link to a review paper that
I stumbled on a couple days ago, and you can
I'm not sure about your battery reading. If you are using a TOS battery
code module like VoltageM, it doesn't work on some platforms and when
it does it may do the voltage calculation for you. Read through the code
to figure that out. You can do make [platform] docs to get a handle
on what
I've seen some talk that the MTS card drivers are not yet,
or perhaps just now, available. You might need to update
your devel tree, or look at CVS.

That kind of depends...if all the motes can hear each other

first. But it doesn't always work. And the micaZ seems to work

I can't seem to figure out whats going on - i'm sure its not the motes

The basestation still only recieves on the packets - This only occurs
when the base station is the source of the transmition

I need to find out if the transmission of a packet is completed at MAC layer

What I need to do is to change some radio parameters. So, I want to make

I'm sorry, can you describe the system a bit more.
I was distracted and didn't really follow the first version.
One thing to check is that you are using the right IDs
if you are sending to specific motes. You could also put
an intentional delay in one of the re-Motes to see if it
is an
The basestation sends out a packet with the TOS_BCAST_ADDR with a
particular seqno. There are two motes which each forward anything
they receive if they have not seen the seqno before. I put in a delay
and still the base only receives one of these. The weird part if
there is another
You can enable the acknowledgment by MacControl.enableAck.
