    CYW43455 wifi adaptivity CCA


      Hi Cypress


      I am using CYW43455(pi3 b+ platform) to pass CE certification, with wl tool version:


      1.141 RC64.24

      w10: Mar 12 2018 16:18:54 version 7.45.222(RPI-PRKE) (r683458 CY WLTEST) FWID 01-35ee9694



      But when we go adaptivity testing, our CCA time is fail (271us measured, but spec is 18~160us)

      Our wl setting is refered to wl manual 4.2.5 as follows, could you give us any suggestion for our setting?
