Hello,
I am using CYW954907AEVAL1F Evaluation Kit with the correspond chipset: wl43909B0.exe
Does WICED supports 40MHz lower and upper sidebands in 5GHz?
When we tried using these commands: "wl43909B0.exe --serial X chanspec -c 38 -b 5 -w 40 -s 1
wl43909B0.exe --serial X 5g_rate -h 2 -b 40" ,
the Spectrum Analyzer shows the same plot with the same center frequency, not the upper sideband .
Best Regards,
Ana

Hello,
The default driver restricts to 20MHz transmission. The mimo_bw_cap will remove this restriction and allow 40MHz to be activated.
Please use this command:
wl mimo_bw_cap 1
Note: This command must be set in the down position prior to the chanspec command

Lower sideband is selected through the -s option in the chanspec command.
-1 Low (or lower) sideband (applies to a 40 MHz channel bandwidth).
0 No sideband (for 20 MHz channel bandwidth).
1 High (or upper) sideband (applies to a 40 MHz channel bandwidth).

The problem is that in cases when I select the lower and upper sideband(40 Mhz channel bandwidth),on the Spectrum Analyzer I see the same plot,no changes applied.

I already used -s for setting the sidebands but it does not work.

Can you please attach the spectrum analyzer plots for analysis?

These are the plots that were rendered for channel 38(which is the center frequency): - First Plot: Lower Sideband( s -1)
Second Plot: Upper Sideband( s 1)
In case we set channel 36 or 40 we get an error as it is a Bad Channel.
