Hi Bastian, Thanks for your reply.

I have just one USRP, therefore I tried the communication between USRP and your contiki code. The log I got always look like a number of Os folowing by Hello Gun Radio, like OOOOOOOOOHello Gnu Radio. What does the O means? > > Just out of curiosity, did you try the transceiver? Is it working for you? > I tried transceiver, it doesn't work. But tx works perfectly. BTW, what have you changed in your code in comparison with the original UCLA Zigbee. Regards, Dingwen
