Re: [riot-devel] Need help about RIOT radio communicate example
Hi Chen, I can remember having the same problem with the telosb. I traced it down to the fact, that there are no interrupts triggered. Which is strange as the same code is working on an other msp430/cc2420 platform (Zolertia Z1). Maybe a misconfiguration somehow sneaked into the radio driver setup. As I don’t have a TelosB anymore I can’t debug it in more detail right now, but maybe this gives you a hint.

(For native mode, the other should show > received packets). Do you have the possibility to use a sniffer somehow? This could be helpful to check if it is a sender or a receiver problem. You could also try to use "make debug" or set ENABLE_DEBUG to 1 in drivers/cc2420/cc2420_rx.c (cc2420_tx.c respectively), to figure out what fails. The last time I checked the driver was working, but I cannot verify right now, because I don't have any cc2420-based hardware here.

Have you tried without setting the channel and PAN?

Re: [riot-devel] Need help about RIOT radio communicate example
Thank you for replying. I connect 2 telosb to 2 USB port and used 2 terminal to "make term" to each telosb board. Then I set addr to each board and the same chan & pan to them. Then I use one board to txtsnd to other board address. But there is no reaction from the other board. (For native mode, the other should show received packets). I also use the .elf file in cooja simulation tool, there is no reaction for receiving node also. And I think the #1442 bug is not a matter about shell(explanation from 2014 dec version), I think it's a cc2420 driver related bug.
