Unfortunately, I don't know exactly, there is no information about range in Datasheet.
It's 8 bit value, and I guess it's same range as RSSI value.

In tinyos 1.0.7 the default value for micaz platform is -128. You should change it going to HPLCC2420Control.init() On 7/1/07, JeongKwanhee <[EMAIL PROTECTED]> wrote: Hello all! I knew CCA default value is -32. And I found CCA_MODE that decided whether data received or not. So, if I want to decide CCA Threshold, what I have to do? I think that I just change default value(E0). Is right??? Plz, give me send many email whether it is right or not.
