Jennifer,
There are two main ways you can decode the packet.
1) At the mote by pulling out the data and pushing it to the serial
port using printf, and the net.tinyos.tools.PrintfClient tool.
2) At the computer, decode the raw packet after receiving it using the
SerialForwarder/net.tinyos.tools.Listen tool.
Each one has it's own advantages/disadvantages. It sounds like you are
trying to do #1. If you using the BaseStation code as a base for you
program, make sure you remove any code that forwards messages received
over the air to the serial port.
In your receive event on the mote, all you have to do is add something
like this:
printf("Counter Value: %u\n", cval);
printfflush();
Where cval is your desired uint16 value. It is important to flush the
printf buffer frequently because it will not automatically start
flushing the buffer until it is 1/2 - 2/3 full(which can make debugging
difficult) . I normally manually flush the printf buffer every time I
make a call to printf so I see the output immediately on the console.

Hi,
Hi,
In fact, i'm talking about the standard message buffer
"message_t" .
you know that the values of the counter represent the data filed
so,
my question is how to recover this data and display it with
printf ?
this is the structure of the message layout
typedef nx_struct test_serial_msg {
nx_uint16_t counter;
} test_serial_msg_t;
thanks in advance

Your explanation is a bit foggy.
Where exactly the problem is? After which step? What does work?.

Hi all,
I'm using tinyos-2.x on windows Xp.
I tryed to follow the tutorial "mote-PC serial communication
and serial forwarder"
and every thing was ok.
Now i want to display data from mote on my PC.
when executed the TinyOS printf library in
http://docs.tinyos.net/index.php/The_TinyOS_printf_Library
it works very well but i can not integrate it in the "mote Pc
serial communication" to display JUST the
data that i sent.
does any one know how to do that ?
i need your help please.
Regards,
Jennifer
