Hi,
With LPL you can do a simple calculation to calculate
a worst case packet delivery time.If sleep interval is
1000 ms then in worst case every hop transmission will
take ~1000ms. Now as hop number of hop increase this
delay grows significantly. This explains the huge
delay.
Also you said abou

Thanks for your explanation :
it means there are four states for a mote :
active(sending a msg, rcv a msg, running a task), idle(ready to run
something but nothing matters at the moment), sleep ( lowest state) and turn
off.
do you know if it s possible to implement a signal wich wakes up
Hi,
I am having problem in compiling application for
simulation. The application compiles when I compile
for mote but fails when I try to compile for
simulation.
I.e. >make micaz works fine
But >make micaz simdonot work.
I am able to compile and run simulation for the other
applications l
Thanks for the answers, but I set the duty cycle to 1000 meaning 10%, so
the sleeping period should be only about 50ms what approves collection
transmitting times... but not the dissemination problems.

Hi Inderjit,
I think that it works when you have uint8_t* p; because for some reason you
have longer message than the length of TOS_Msg. Then only when you have
defined the pointer, you have enough space.
You have a check for valid length, and you compare with this expression
MSG.length > TOSH_D
Hello,
I have been trying to use SplitControl to switch the radio on/off. I put the
line:
uses interface SplitControl as RadioControl;
in my module.
I've also implemented all RadioControl.initDone(), startDone() and
stopDone() events.
The problem is I can't do the wiring:
Main.SplitControl ->
David,
Thanks for your time!!
You were right I was using an old version of CC2420ControlP, since I was
compiling using the BaseStationCC2420 that incorporates the
CC2420ControlP old version.
I just simply used the new BaseStation and the ack started to appear...
so once again thanks!

Hi,
Is the following correct?
The serial number of a tmote (telosb) mote shown by motelist is specific
to the serial-USB-converter chip on the mote. It cannot be read from the
mote and it is independent of the serial number stored in the DS2411.
Cheers,
Urs

Sorry to post this again. Forgot to provide the platform information.

Hello.
I want to know when posted task will be rerun ?
What I know right now is as follows.
1) I have to define task function
task void taskFunction() {
// some code
}
2) I have to post the task function
post taskFunction()
I know that System scheduler manage the posted task. Also,t

What do you mean by "If wrong, do I have to use another code in order
to rerun posted task ?". I assume your question is really whether you
will have to repost the task yourself if for some reason the posting
fails. In TinyOS-1.x there is a limited size on the task queue, so
the possibility exist
Hi,
I'm making modules that are just a wrapper of Msp430Adc12MultiChannel
interface so I can add some different logic code to it once
it works as a wrapper, and I'm stumped at the moment...
Testch12AdcC.nc configuration wiring is my guess...
The Test modules are prototypes of a 12 channel soi
I am using 4 motes to test a multihop network. Mote 2 & 3 send data to mote
1, and mote 1 after aggregation forward the data to base station (mote 0). I
can see mote 1 receiving and sending data by blinking LEDs.
But initially the data is not displayed in the moteview. After some time
mote 1 stops
See the definition of the Msp430Adc12MultiChannel interface.
For any interfaces you use you have to implement all of the events
they provide. Even if you don't want to do anything in them. Just
leave them blank.

In the body of your ReadNow.readDone() event you would want to post a
task that then signaled your Read,readDone() event. Your application
wouldn't receive the results at exactly 2 kHz (because of the delay in
posting the task and the scheduler actually running it), but the
samples should be gathe

This flag shouldn't be application dependent. When you set the flag at
compile time, or adjust the interface and call CC2420Config.sync() at
runtime, the address recognition settings should change. With address
recognition off, your mote should be receiving packets that are destined for
I am trying to read serial data from pin 4 of the
10-pin header of the Tmote mini.
i have downloaded the Tmote TestUart0 example (Using
the Shared UART0 for External Devices), and

I used a oscilloscope on pin 4 to verify that data was

Ahoy there!
I am currently trying to use LogStorageC services, but I am
experiencing some problems.
I've noticed that the wiring
LogStorageP.At45db -> At45dbC;
is missing in LogStorageC.nc. Is it supposed to be like that?
LogWrite.appendDone simply returns len=0 and error=FAIL.

Urs, I have did some fetching upon sensors and stuff, but the data is

I found a missing wiring to autoRVG module and got a compile
of my Adc mux sensorboard modules.
Are these compiler warnings needing investigation?

Hi all,
I am using the LogStorageC component to log stuff, it seems that:
The LogWrite.append() command actually update(increment) the address when
it's logging.
However, the logRead.read() command doesn't do the above.
As a result when I try to read the flash the result will always be the first

I figured out they are about lacking return of SUCCESS or FAIL is all.
Nevermind.

One other thing (if I don't discover soon enough):
How do I establish a volume's valid last page? I mean, I erase the
volume with one application, but sync doesn't work after it. Later
attempts to write also fail, as though there were no valid metadata
pages in the volumes. Can someone please help
