AIROC™ Wi-Fi and Wi-Fi Bluetooth Combos Forum Discussions

Hi Infineon,

We do have a prj that planned to use CYW4373E (USB type) to work out the Wi-Fi AP feature, and the one of the mandatory is to  acquire the Wi-Fi Alliance(WFA) WPA3-Personal certification for AP mode. so the question is :

 1. We saw the data sheet of CYW4373E to show that it's to support WPA3-personal. but it doesn't show that it's to support for STA or AP mode, so the question : Is it to mean that CYW4373E supports WPA3-Personal features for AP mode ? or only to support for STA mode ? or both ? any comment ?

2. As the data sheet of CYW4373E to show that it's to support WPA3 personal, and the latest SPEC of WPA3-Personal is R3. so the question : Is the present CYW4373E supporting up to R3 ? or only R2 or earlier ? or or any comment ?

3. Is the present FW/SW/tool of CYW4373E ok to pass the test of WPA3-Personal R3 for AP mode ? if it's, can you show us where it's to download the FW/SW/tool ? or any comment ?

Thanks,

PeterC

Dear Sir,

When I do iperf test, the error is shown.

After the error message is shown, we will not use "wl" command.

What is mean for " brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110"?

The issue is not easy duplication.

Do you have any suggestions?

Dear Sir,

Do you have any throughput reports (5G/2.5G)for our reference?
My environment is Sigmastar SAV530Q(SDIO 2.0)+Linux kernel 4.9.84+CYW43455.
