I have qustion about function Energy Detect in SMAC.  
In my project END device most time work without PAN,i.e they permanently have to energy scan for search suitable PAN. When PAN appear it transmit Beacon frame
1 time in 1 second. Therefore END device have to scan minimum 1 second and then sleep some time. When did Energy Detect function finish? How long time does it take? Does this function find beacon frame? It's important for me.
I can do it in another manner. I don't use Energy Detect and  simply turn modem in RX mode for 1 second. If I don't receive any frame it's mean - channel clear. If I receive frame then I can check LinkQuality and some paremetrs of PAN. Then I can select suitable PAN.
What do you think about it? What is method  of scanning more correct?
Added p/n to subject.
