I am testing for certification using CYW43907 product.
I knew that this product is certified as 2.4G & 5G 802.11n
But It has problem for HT40 MCS.
What's the problem?
I set up device with following command.
wl4343WA1.exe --serial 5 down
wl4343WA1.exe --serial 5 mpc 0
wl4343WA1.exe --serial 5 phy_watchdog 0
wl4343WA1.exe --serial 5 country ALL
wl4343WA1.exe --serial 5 band a
wl4343WA1.exe --serial 5 5g_rate -h 0 -b 40
wl4343WA1.exe --serial 5 channel 36/40
wl4343WA1.exe --serial 5 mimo_txbw 4
wl4343WA1.exe --serial 5 scansuppress 1
wl4343WA1.exe --serial 5 phy_txpwrctrl 1
wl4343WA1.exe --serial 5 txpwr1 -1
wl4343WA1.exe --serial 5 phy_txpwrctrl 0
wl4343WA1.exe --serial 5 up
wl4343WA1.exe --serial 5 phy_forcecal 1
wl4343WA1.exe --serial 5 pkteng_start 00:11:22:33:44:55 tx 100 1024 0
Then I measured the TX radio.
The result is bad. that spectrum was only 20MHz band, not 40MHz.
I attached it.
The firmware & Wiced version of the device I used is as follows.
Starting WICED vWiced_006.001.000.0085
Platform MVT001A initialised
Started ThreadX v5.8
Initialising NetX_Duo v5.10_sp3
Creating Packet pools
WLAN MAC Address : 44:91:60:28:5A:3C
WLAN Firmware : wl0: Feb 12 2018 23:35:27 version 7.15.168.108 (r683813) FWID 01-81fd72af
WLAN CLM : API: 12.2 Data: 9.10.74 Compiler: 1.31.3 ClmImport: 1.36.3 Creation: 2018-02-12 23:30:46
Solved! Go to Solution.

Hi:
I think you need to use chanspec for this setting.
wl4343WA1.exe --serial 5 channel 36/40

hello:
wl4343WA1.exe is not used by 43907 , I think you need to use
43xxx_Wi-Fi\libraries\test\wl_tool\wl43909B0.exe to have a try .

Hi zhez
Your advice has been tested and the problem has been resolved.
Thank you very much.
What is the difference between channel and chanspec ?

hello:
"wl channel" is only designed to change channel like changing from channel 1 to channel 6, but can't change bandwidth .
