This will be dependent on your settings.

First if you choose PQT or CS based selection (Section 9.9 in the UserGuide http://www.ti.com/lit/ug/swru295e/swru295e.pdf). Section 6.8 describe PQT, see http://www.ti.com/lit/an/swra413/swra413.pdf for CS time calculations.

Hi, TER, Thanks for your fast reply.

like to choose the PQT based for antDiversity. just check the section 6.8, still dont know how to calculate the min preamble length request.

continuous switch antennas for looking preamble words, it looks like no need special preamble length request, right?

Thanks.
