Hi, Sorry, I must have missed your reply earlier (it helps sending replies also to the mailing list). In what setup does your Oscilloscope application work? When the sentilla mote is connected to the computer? Maybe the sentilla mote is somehow different from the other motes and uses a different frequency. If one of the tmotes is your basestation, then radio communication seems to work. Maybe you could try a different test program like the BlinkToRadio (or whatever it is called now): http://docs.tinyos.net/index.php/Mote-mote_radio_communication
