[Tinyos-help] Can anyone help me clarify the MicaZ (CC2420) radio stack?

[Ruoshui Liu]

Dear all,

Currently I am working on the MicaZ using CC2420 radio stack, and I am 
trying to completely disable the CCA function implemented by CC2420 
radio stack. However, I did not find the right function to do so. 
Therefore, I went through the *Mica High Speed Radio Stack *and the 
*Mica2 (CC1000) Radio Stack* stated on the web: 
http://www.tinyos.net/tinyos-1.x/doc/.

The question is what is the difference between the *Mica2 (CC1000) Radio 
Stack *and the *Mica High Speed Radio Stack*. Is the Mica2 (CC1000) 
Radio Stack totally different deign from the Mica High Speed Radio 
Stack, or interleaved design with it? They really confuse me!

The other question is that where I can find the detail of *MicaZ 
(CC2420) Radio Stack *implemented with TinyOS 1.1.15. I know there is an 
article describing the *MicaZ (CC2420) Radio Stack*, but all the 
functions stated in that are implemented in TinyOS 2.0 which is not my 
case.

I really need to find the right function to disable the CCA in CC2420 
regardless whether the channel is busy or not by using TinyOS 1.1.15.

Many thanks!
