Thanks very much again.
Now I am having another question: are the values acquired by reading RSSI_VAL
register supposed to be the same as those retrieved using
CC2420Packet.getRssi()?
Because when I compare a same application with the two methods, the RSSI I
get are actually different.

Hi,
I just download the tinyos-2.x-contrib, and trying to compile BMAC:
\tinyos-2.x-contrib\*wustl\upma\apps\tests\TestBmac*
But getting compilation errors. I am using TinyOS2.x.
Following are the errors: (DO i need an old version of tinyos ?)

Hi there,
Does anyone have an implementation of Crossbow XServe for Linux/Ubuntu?
Trying to use it with MicaZ, if possible.
Thanks!

Hi all,
I would like to know which mac protocol is used by tinyos-2.x? Is it B-MAC or
1.1.1 MAC?If I want to change the type of the MAC how can I do that?
Thanks in advance,
Kartik

You should be able to use VoltageC to get the value.
The difference in the two DemoSensorC examples you
have is that someone decided to use DemoChannel
as an intermediate name rather then DemoSensor,
probably to enhance code re-usability (not).
It may be that the simulator implementation returns

On the node the message is configed as:

Sinan,
I actually have an alternative cc2420 radio stack implementation under
tinyos-2.x-contrib/vu that does what you want. That is, the msp430
timer subsystem is reprogrammed such that timer A is the 32kHz timer
and timer B is the micro timer. The radio stack uses the micro timer
for timestampin
Sinan,
Things are not that easy, unfortunately. For port 4.1, that's where
the interrupt line of the cc2420 is connected, you must use timer B
for capture. This means that you will need to reprogram the whole
timer subsystem such that timer B is driven by the internal DCO, and
timer A is driven by
Hi again,
I wanted to add some comments to my last reply.
When I connect Timer A to SFD, I could get time= 0 from *async event void
CaptureSFD.captured( uint16_t time )* and it means all timestamps are
invalid. Also, I could not get time values LocalTimeMicroC component and it
always returns 0.
Hello, I am wondering how I can return and display the battery level of
micaz motes. I wish to retrieve battery levels from micaz motes and
broadcast these values to other motes who will store them in a table,
perhaps to try routing via these values and AODV, and am wondering how to go
about this?
Hi all,
How can a sensor node receive packets from another sensor node using Xmesh
(Crossbow) and TinyOS1? I read the material and I just saw the upstream
transmission mode using sink nodes, but I want a communication between
sensor nodes (source and destination). I changed the source

Hi Thomas,
I am working on a similar platform to Telos I think... (It is Genetlab
Sensenode platform). I have connected TimerA to the SFD line as you said. I
have modified the file HplCC2420InterruptsC.
configuration HplCC2420InterruptsC {
provides interface GpioCapture as CaptureSFD;

Do you really need to read from the serial port from the python script?
How about using the C serial forwarder and attaching to the serial forwarder

Hi everybody,
I use telosb motes in my network.
I want to read from the serial port by using a python script, but it
doesn't read well.
Is 115200 the correct baud rate?
Here is the code:
#!/usr/bin/python
import serial
import time
def main():
var = 0
ser = serial.Serial(port='/dev/tty
