Hi,I am a new in tinyos. Now I have some questions about the motetest thing. If
you have time, could you please help me out?I have one motetest program running
on the stargate, one TOSBase runs on one mote (this mote is connected to
stargate), another mote have program named CntToLedAndRfm. I try to get
received data printed out. But it never happened. I couldn't figure it out what
was wrong. Could you please tell me what goes wrong here?
The following is the motetest.c, I only comment out the create packet and write
packet out. Also I set the groupid with 0x33. I don't know why. More infor: If
I unplug the mote (have TOSBase) with the stargate, the green night blink. If I
plug it with stargate, no night is on. And nothing was printout when I run
motetest. Thanks a lot a lot~~Xiaodan#include <sys/types.h>#include
