Hello everyone, I want to reduce the range of tmote so that i can get a multi hop topology. There are posts that say to change the CC2420Radio file parameters. Which parameters should i change in which file in that folder ??Thanks,Bhushan

Youmustreduce the transmission power.
With "SetRFPower" (C:\cygwin\opt\moteiv\tos\lib\CC2420Radio) command you can
adjust the transmission power from your aplication. If you do not use this
command, the default power transmision is set to 0x1F (31 - 0 dBm - max
power) in "CC2420Const.h"
Hi
,
In
socketswe say that the domain types are like AF_INET and
AF_UNIX,
the first is used
for the Internet and the second one for the UNIX IPC,does
it mean that to
AF_UNIX domain is used to communicate with the process
running in the same
machine if yes during what secnarios do we use
Hi all,
I am writting to you in order to know if there is already an aplication for
nodes localization. I have read part of the literature about nodes
localization to know which algorithms there are. I have met with ROCRSSI
algorithm. Has anyone implemented it? or which ones have been done?
Thanks for the answer. I overlooked the indication on the datasheet,
that 10uA is the max value.
I would appreciate any suggestion to what I've done wrong with my
measurements.

Hi all,
i created a simple program for broadcasting messages where every mote
broadcast its ADC readings.
If i install it on my motes it seems it works (i look at leds' work), but i
cannot run TOSSIM.
I type make pc and it's ok. Then ./build/pc/main.exe 5 for example and i
can look at some
Hi, Sara
I am not sure if you have found out the
reason why your RSSI value is not correct. Basically CC2420 uses 2s
complement for RSSI value.

However, I have also done my measurement on the signal
Hi!
Thanks for the ideas. Yesterday I realized what wasn't working. I had to
recalculate the crc and now it is working. Very strange, but as long as it's
working I don't mind:)

OK, I'm starting to get the picture I think...
But can you just send me the whole module code,

Hello,I'm trying to measure the voltage of the batteries of my micaz nodes.When using the VoltageM component, I'm always getting values like Vbat= 3901, 4638, 4892, 5261, 5398, 5351, 5445, 5398 - So, 5,3 Volt for two AA batteries?? Seems very strange...

I'm using MoteWorks 2.0, so I don't know which TinyOS tree it is. rpm -qa
shows:

avr-libc-1.2.3-1
avarice-2.4-1.xbow

nesc-1.2.4-1

The existence of this bug is easy to check anyway.
Dear David and Henri,
Thanks for your answer.
First about debugging information. If I start a SerialForwarder with the
-debug option, I do not get any message when the SerialForwarder stops
forwarding.
I also tried to use the C SerialForwarder, but I must be doing something
wrong because I do

Just to add to my observation, when I use the 'C' SerialForwarder and
send a command to the mote to read from the flash, I get the the
following error message :
Note: sync
I am not sure what this error message means in the context of the serial communication ?
Thanks,

I don't think this is an 'error' message. This message appears when SF is functioning normally.- VinayakOn 5/19/06, Avinash Sridharan

I don't remember the solution to the problem in the previous email you
reference, but I think they were reading the wrong ADC or getting
wrong values somehow...perhaps Gina Upperman is still online here and

But your values look suspiciously like they have been divided by two.
Do you
As to the use of mica2 files in micaz, David Gay (I think) once sent me
a pointer to doc on the nesc include path...which I of course cannot find
now...but that's the way it works. There's some worse ones that go all
the way back to mica, and I think even avrmote (but don't quote me on
that).

I assume it's the same trick as the mica2 where the ADC Vref IS the
battery, and you get an inverted reading from the internal ref which
increases as the battery voltage droops.
Is there a micaz schematic on the XBOW site? I keep looking for one at
http://www.tinyos.net/scoop/special/hardware
Yes I know they are very suspicious ;) But I don't have any bit shift anywhere in my program(s)... Those are the actual values I'm gettingMichael, in your robocode you're getting the right values for mica2? But you're not using the VoltageM component.
So, I decided to try the same thing you did:
I did the excavate thing a while ago and satisfied myself that
the mica2 uses the moral equivalent of the Battery as the Vref.
Since I couldn't find the micaz schematic I just assume that it's
the same. I don't know why the 'Z uses the internal ref and the '2
has an external one. Maybe it's that
Don't use my Robo code for Bvoltage. I have a whole different hardware
scheme and it gets different values. However, you should be able to
get the raw ADC readings using ADCC the way I do. The mica2 and 'Z
hardware are different as well, which is why they read different
channels, so your mileage
