Hi,
When packet is receive,RadioReceive interface generates
*receive*event which posts RadioRcvdTask() whose function is to send
that packet to
UART.When UART receives the packet, it generates receive event which posts
UARTRcvdTask() whose function must be to send it to PC. Instead, it sends

when i read the file TOSBootM.nc , there are some things i can' t

when the cc2420 radio receives a packet, it checks whether the CRC bytes
in the packet are correct or not (via HW). and then it replaces the two
CRC bytes at the
end of the packet with RSSI information and some correlation values, and
only
one bit to tell whether the recieved packet had valid
In CC2420ReceiveP you will find the following comment and code:

Hi everyone,
Has any work been done towards the performance evaluation of CTP in
tinyos2.x?I failed to find one. I mean a comparative stduy of CTP vs. other

Thanks!

Recently I have started studying some protocols for tinyOS,
and I wanted to test some, by installing them in the motes.
However, I found some protocols codes only for the TinyOS1.x version,
are there any TinyOS2.x protocol codes available for download?
Furthermore, if any tutorial is available

Hi all,
I would need to do BER/PER measurements using 2 micaz motes. In cc2420 says
that this could be done using test mode 2 but it doesn't say specifically how
to do that, anyone knows more about this?
Thanks for any help,
Rodolfo.

Do you have a link to the sensor data sheet?
You probably should look at the data sheet for the MSP430.
I'm overdriving the inputs on a telosb, of course they clip but it doesn't
seem to have any significant effect.
If you need to drop the voltage to 3 volts, it should be fairly easy

Sir,
Why is it that the range of my input into the telos ADC port must be ranging
from 0-3V? why 3V? is it because the battery supply is 3V? Thank you.

Hi Damien and thanks,
If the value is 0 then it just waits for the next packet overwriting the
original once it arrives.
There is no event launched at the top
layer ?
Suppose that I should copy the wrong message (with CRC=0) before the
next arrival. I have to
capture the event
I don't understand...
The code you include is presumably called when a message is received over
the UART. It calls RadioSend.send(), which, if names are to be believed,
sends a message over the radio. The last time I looked at RadioRcvdTask()
(or whatever the symmetric function is called) it
Yup. Anything over 3 volts is wasted, and may overload the input pin.
Although as others have pointed out it's generally ok to over-voltage
even though the specs say not to.

Hi,
Thanks for reply.
After message is received over UART, in my opinion it should be delivered
to listen tool.Why is it sending over the radio again?
Is TOSBase working as transmitter also?
TOSBaseM.nc is attached.

OH, maybe I get it now...
TOSBase is to be used as the base-station on your PC. It passes
messages between the radio (from re-Mote devices) and the serial
port. The Listen program (or other host based software) sits on
the other end of the serial. It only makes sense when it's on a
piece of real

Hi,
I am wondering how to measure the energy consumption in TinyOS 2.x?
For example, the energy consumption of transmission of packet? receipt of
packet? etc.
Thanks,

I think one of several ways to do is to have a look at CC1000/2420
datasheet. They provide current consumption required for transmitting at
various transmission power levels.

I think that would require special equipments in order to measure the

You need to set up an ammeter to measure the current and probably a voltmeter
to measure the voltage. I think the best way would probably be to put a shunt
in the voltage supply line and measure the voltage drop across that for current.
You can just measure the voltage from the power supply line
Gary,
Do you have an oscilloscope at hand? If yes, you can do it as described
here: http://focus.ti.com/lit/an/swra144/swra144.pdf
I'm not sure, though, if you can measure such short events as reading a
sensor...

By default LPL is off by default in the rf230 stack. It can be enabled by
defining the LOW_POWER_LISTENING preprocessor variable (e.g. by adding
PFLAGS+=LOW_POWER_LISTENING to your Makefile. Apparently, we forgot to update
AntiTheft since LPL has been added to the rf230 stack.

Hi Alessio,
If I'm not mistaken, then the CC2420 radio chip doesn't come with a
preprogrammed MAC address. I think the radio supports different MAC
address lengths, depending on the protocol that you use. TinyOS uses
2-byte addresses, the node-ids (the ID with which you program the
motes). In
