I am using TinyOS 2. The radio chip is CC2420. I found that when the channel is always busy, the radio stack of CC2420 now will sense the channel(CCA),and then call congestion backoff for the channel is busy. After that, it will go back to sense the channel again. This is a endless loop, the stack will not give up this sending, and the upper layer is blocked.
I wish to break this loop. When having sensed the channel is busy for a couple of times, it will give up the sending action, and tell the upper layer. I have try some methods, but they don't work. Is there anyone could give me some suggestions?Thank you for any help. nathan
