Hi,guys

I use Oscilloscope in tinyos2.0 to send data of temperature sensor.
After setting up the device with the motes,I use matlab to access the serial 
port as:

port = '/dev/ttyUSB0';
listener = serial(port,'baudrate',115200,'DataBits',8);
fopen(listener);
while(true)
    clear msg;
    msg = fread(listener,1);
    msg = double(msg);
    display(msg);
end

And what I get from variable msg is like:
msg = 0
msg = 25
msg = 0
msg =238
msg = 214
...

My question is how to get temperature data from this msg?
Thanks
Xiao
