Installed Sensorboard ?

Hi, I would like to know if there is a way to know at runtime which 
sensorboard (if any) has been installed on a Mica2 mote. The program I'm 
writing basically shows the topology of the network and allows the user 
to read a sensor value from a chosen mote; however not all motes have a 
sensorboard installed and in future the sensorboards may be changed so 
it is necessary for me to know at runtime the sensorboard id (or any 
other data that may help in identifying the installed sensorboard). 
Thank you.

Alessandro.

A question about tossim


hi,everyone:
 
 
     Recently i have read the manual "TOSSIM: A Simulator for Tinyos Network" . In section 3.2 about Bit Error and Packet Errors,the original text i attached below.
 
The formula for calculating packet error rates (Ep) from bit error rates (Eb) for the mica RFM 40Kb stack with SecDed encoding is:
Ep = 1 -(Ss · (Se)^d)
Ss = (1 -Eb)^9
Se = (1 -Eb)^8 + (8 · Eb · (1 -Eb)^12)
Ep = 1 -((1 -Eb)^9 · ((1 -Eb)^8 + (8 · Eb · (1 -Eb)12))^d)
 
 
I have problem about these formulas.
 
for example ,in the formula 2, why is the exponent 9.
 
so can anyone give a more detailed material  to understand this formula?
 
thank you !

Re: #ifdef support in nesc.

You need to also wire the components' interface together. For example,
do you have in your configuration sth like

#ifdef CHIRP_ENABLE
  SurgeM.StdControl -> Sounder;
#endif /* CHIRP_ENABLE */

but as i know , just call  timer.stops();right??
 
and we know that when we write a program ,we need to write :stdControl.stop().
but if i want to stop my sensors ,how could i do ??

uisp: Direct Parallel Access not defined

Hi,

I am using mica2 motes and installed tinyos on Debian. When I try to
install the application using uisp (make mica2 reinstall.0
mib510,/dev/ttyS0), I get the error "Direct Parallel Access not
defined".

Could any one help me to solve the above problem?

Regards,

Re: how to let mote sleep

Whenever there are no more tasks to run, TinyOS automatically sleeps.

Deluge on TelosB - no ping response

Hello,
 
I've done many reinstallations of TinyOS trying to get Deluge to work on my TelosB motes with no luck.  My latest configuration was a manual installation of TinyOS 1.1.15 with the Cygwin environment updated accordingly.  I followed the instructions here for setting up Deluge:
 
I get no response when I run deluge --ping.  In fact, the TX LEDon the TelosB doesn't even light up.  Is there anything obvious that I might be missing?
 
Thank you in advance!
Tim

To be specific, when there are no tasks to run, TinyOS sleeps the  
processor. But the processor is often a small part of the overall  
energy budget. There's also the radio, sensors, etc.

Event Generation

Hello All,
I am trying to simulate events in TOSSIM. For example, I want a mote to start chirping and all its neighbors are going to listen and then broadcast a message. How can I do this?
Thanks
