do XBee 802.15.4 products use CCA mode 1 or 2?

Hi all,

I was wondering if anyone knows some of the low-level details of XBee 802.15.4 products to know if they use a CCA mode of 1 or 2? If they carrier sense the medium using a CCA mode of 1, then they only do simple energy detection. If they use a CCA mode of 2, then they carrier sense for other 802.15.4 signals.

Thank you!

Hello gnychis,

What do you mean with CCA 1 and 2, I mean where do you set with that modes? I didn’t see anything about any mode for CCA.

Another thing. Do you know how to se the CCA Treshold for Transmit or not when the energy of the channel was above the treshold?
