CC430's clear channel assessment

Recommended Posts

Hey guys, anyone uses CC430? I need some help with a using CC430's Clear Channel Assessment feature, particularly with these 2 questions I posted on TI's e2e forums:

Basically I only get the CCA interrupt signal asserted once and after that, it always fail. A reset lets the CCA signal asserts again. I've been wrecking my brain for the last week and couldn't come up with a solution.  An answer here or the TI forum would be great.

 

Thank you.

EDIT: Problem resolved.

I haven't used CC430 since 2012, but, when I did, I found that the CCA was highly unreliable.  It was far better to measure RSSI and check it against a threshold in software.
