Ensure that your TOSSIM simulation has started before you start capturing packets. Are you directly using Oscilloscope (without SF) for listening?

dear all, I have followed you guys kind suggestion, and set the MOTECOM by using " export MOTECOM=tossim-serial", but what it returned to me is [EMAIL PROTECTED] died -- restarting I also used the serialforwarder, and it also had that problem, the server port is 9001 Still not work :-(, whyyyyyyy >.< Thanks for your answer.

Here [EMAIL PROTECTED]:baudrate says to listen to a mote connected to a serial port, where serialportis the serial port that you have connected the programming board to, and baudrate is the specific baudrate of the mote. For the mica and mica2dot motes, the baud rate is 19200, for the mica2 it is 57600 baud. You can also use a mote name as the baudrate (in which case that motes baudrate is selected).

If you don't have the javax.comm package installed properly, then the program will complain that it can't find the serial port. If you do not see that data lines on the screen, you may have chosen the wrong COM port or the mote may not be correctly connected to the computer.
