WICED Studio Wi-Fi Combo

We are performing EMC testing on our product which uses the CYW43907 WiFi combo chip on a WM-AN-BM-23 module.

We are doing the testing with the wl_tool provided and have not had problems until now. We are using Wiced Studio 6.2.

Our testing house is reporting a failure with an error of -20 which seems to be BCME_BADCHAN.
However we have not found this error code in the documentation, could you tell us where to look.

.\wl --serial (comport) chanspec -c 3 -b 2 -w 40 -s 1

They tried changing the channel, they get the same result.
43909B0.exe
They can transmit fine in the 5 Ghz band, eg using:

.\wl43909B0.exe --serial (comport) chanspec -c 38 -b 5 -w 40 -s

 

Is it possible that your team could provide insight into whether 802.11n 40 Mhz is supported in the 2.4 Ghz band and if so could you provide a bat file or at least provide the commands to transmit.

Hello:

HT40 in 2.4 is not supported as it will bring a lot of interference.

.\wl --serial (comport) chanspec -c 3 -b 2 -w 40 -s 1
