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?

sudo ./wl -i wlan0 out

sudo ./wl -i wlan0 down

sudo ./wl -i wlan0 frameburst 0

sudo ./wl -i wlan0 ampdu 1

sudo ./wl -i wlan0 country FR/5

sudo ./wl -i wlan0 bi 65000

sudo ./wl -i wlan0 phy_watchdog 0

sudo ./wl -i wlan0 mpc 0

sudo ./wl -i wlan0 txchain 1

sudo ./wl -i wlan0 mimo_bw_cap 1

sudo ./wl -i wlan0 2g_rate -r 1

sudo ./wl -i wlan0 up

sudo ./wl -i wlan0 phy_forcecal 1

sudo ./wl -i wlan0 join "MY_AP"

sleep 5

sudo ./wl -i wlan0 status

sudo ./wl -i wlan0 phy_ed_thresh -70

sudo dhclient

iperf -c 192.168.x.x -u -b -l -i 1 -t 10000

Regards,

Joseph

Hello,

The attachment contains the firmware binary but not the blob file.

Also as per the ETSI spec, the CCA time is said to be greater than 20us. I could not find the upper limit of 160us for CCA. Can you please share the source of this information.
