Hello all,
In a lecture for Philipp Levis at Stanford university (
http://www.youtube.com/watch?v=j6hRsue5b30) he said that the time to post
and run a task in tinyos needs 80 cycles (10 micro sec). please any one
knows how we can calculate or measure these times?
Thanks and Regards,

I'm a student of Information Engeenering of University of Pisa.
I'm working with TmoteSky ( cc2420 radio stack) motes and TinyOs 2.x with

Your opinion is right.
I think so.
But, in experiment rssi value, I confused above conclusion.
For example, when 1---à0 exists just only one pair, we assume measured rssi
value of 0 node is -80dBm.
After that, added 3---à2 by adjacent node of 0 node.
But, rssi value of 0 node is still
Probably only one is transmitting at a time due to. CSMA.

What should i do?
I have no idea, please help!!

Thanks Janos for your advices!
I've changed the serial speed to 230400 (because of serial speed declarations

Hi,
I'm facing a similar problem!
My protocol requires a strict time control on when the the packets are
actually transmitted from the base station.
I have programmed by base-station-mote with the BaseStation app in

On the PC, my java program uses a the MoteIF class to
There are defines in the apps/Make*local file for selecting

Randomness of time taken to broadcast is a feature rather than a bug.
Most of the indeterminate delay is due to MAC backoff and free channel
testing. If someone else is transmitting you have to wait until they're
done. Search this list for a lot of discussion on radio timing.
A workaround would

Hi,
I am stuck with a strange problem. I have two modules M1 and M2 which
contain a milliseconds timer each. After M1 has finished some
processing and has stopped its timer it signals an event to a module
at a higher level which then starts a function in M2. This function in
M2 starts a timer
Thanks for the answer. But you did not not get the question
Probably I should have not used the word random. I just meant that the
delay was unpredictable.
I had already significanly removed that randomness due to CSMA backoffs in
the BaseStation app.
Max initial backoff was reduced for 0.9ms

After looking at the code it might be possible (although very

Abhishek:
There is just too much jitter in the delays in the pc-mote
communication, especially if you use java. Most of this jitter you just
can't control (JVM, OS, USB, etc.)
Have you considered moving the timing-sensitive code to the mote?

Hello Everyone
Does anyone know if there are any drivers or example code for using
tinyos-2.x and Crossbow's MDA-300?
I've had a look but only found stuff for tinyos-1.x.

Hi Romain,
I was getting errors with ConverterM module saying that AMSend already
has been previously defined but I was able to fix that by commenting out
the Loopback code from MHBaseStation application and it compiled
correctly. I am now able to install MHBaseStation on node1 and tymaluate
Hi Romain,
In tymaluate, you use Receive interface in the 4 tasks. The Receive
interface does not have the getpayload command, so compiling this
program gives an error. I think this is because of the big switchover in
AMSend,Packet, Send interfaces... and now Packet provides these
commands. So I
Yeah, I'm considering that. But that involves some major changes in the
BasStation app.
Currently it stores the packets received from the pc in queue and sends thru
radio them in a FIFO faishon.
But this doesnt suit me. I want the packets to be sent according to the
timestamp when they are
