I am trying to debug the problem and right now I am not able to receive
any nucleus message to TOSBase node at all. I couldnot find the reason
but by changing log4J settings I could see the following out put.
Please explain what it is?
The following statements appear when log4j is set as:
Dear all,
i would like to ask you some questions about CC2420 and micaz energy

I read, from reports and data sheets, that the Basic RF library in CC2420
contains only a small subset of the 802.15.4 standard: beacons is not
implemented, no defined coordinator/device roles,

Well, i'm thinking about..when i tested the FlashBridge interface, i used a
mote connected to the programming board, and everything was perfect. And
without using the radio, so without send/receive interfaces. i only worked on

Hi all,
Ihave a implementation of a mobile mote which is able to receive moteID, RSSI_dbm and LQI readings from the surrounding motes.
My question is:
Can i perform localization with my received values using codes from Calamari?
Thanks.

Hi,
Yes I've managed to get it to work (although I think it may still be a bit
buggy). The main problem is keeping track of the use of the clock.nc interfaces
and headers. The versions from Vanderbilt share the same names, but differ in
functionality from the standard tos libraries.

Hi,I would really like to see somebody clear things up for me:In the CC2420 datasheet it says, that you can switch from All RX states to TX_CALIBRATE issuing a STXON of STXONCCA.What happens if the CC2420 is in state RX_FRAME

Hi all,
Perhaps we did not explain our problem right. We have micaz motes and TinyOS
1.15 or MoteWorks, in some computers. We would like to know if the elements,
as XMeshBinaryRouter, Bcast or XMeshC, could be used in an application for
Telosb.
In fact, we want to know more about TelosB
Ya, that is interesting. I didn't look at the schematics - I just assumed
they were on the same bus. I can access the radio fine and the flash fine
seperately, but sometimes accessing both has crashed the mote for me in the
past.
And as far as reading vs. writing, I think it would depend on when
Hi,I had a look at the implementation of LFSR in TinyOS.While the implementation is quite short I wasn't able to get the concept behind it.I am familiar with the basic concept of generating random numbers using linear feedback shift registers.
But usually this is done in another way.1. I don't get

Hi,
Has anyone installed TinyOS on Suse Linux? On TinyOS installation page
(http://www.tinyos.net/tinyos-1.x/doc/install.html#linux), I only found
instructions for RedHat Linux. I guess the rpms are platform dependent.
I tried downloading the rpms and installing them, but I got the errors:

As far as I understand it the micaz uses a simple CSMA, where it listens
for a radio signal above a squelch value just before transmitting. If
it hears anything it does a randomized backoff/retry.
For power voltage, I run on regulated 3.3v. I looked at the spec sheets
for the chips (actually the

Yes, it is enough to call SplitControl.stop() to power down the
CC2420. Stopping the voltage regulator also stops the oscillator.
