Dear Sir,

Environment:5G 802.11ac.
The bcmdhd F/W is from internel AMBA CV2X firmware.
FMAC F/W is from "FMAC-2021-10-20".

Chip:43455

We use the bcmdhd F/W and FMAC F/W to test throughput.
We find the difference with data rate and throughput.
Bcmdhd F/W is better than FMAC F/W not matter data rate and throughput.
Data rate of Bcmdhd F/W is 132Mbps.
Data rate of FMAC F/W is 72Mbps.

Question:
1.Is it correctly in the data rate.
2.how to set data rate of FMAC F/W to Bcmdhd F/W.
3.how to improve the performance.

B.R.

Bill.

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?

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

We're looking to prototype the new standards being developed in ETSI ISG NIN https://www.etsi.org/technologies/non-ip-networking over wireless PHY, and would like to do this on Raspberry Pi which we understand includes the CYW43438. There's detail of the technology, which has already been implemented over wired links (gigabit Ethernet PHY), at http://www.ninetiles.com/Flexilink_details.html
The packet format is different from TCP/IP and we also want to be able to set up schedules for ultra-low-latency flows.
We think this would require modification of the CYW43438 firmware; is there a way we could get access to the necessary documentation, libraries, etc, please?

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.

B.R.

Bill.

Does our Bluetooth stack support BLE Audio?

AoA,AoD ,our IC  support these? 

If not, when will it be supported,

Best  Regards,

Moon

Hi

I use Cypress 4343  - my component is Laired sterling..

I see problem with scan results,

In my environment the RSSI value that print in the log is "OFF".

I check inside the code and I found that this "OFF" arrived from WICED_SCAN_RESULT_FLAG_RSSI_OFF_CHANNEL

but I don't understand what the problem? who set the flags to be WICED_SCAN_RESULT_FLAG_RSSI_OFF_CHANNEL

Can you help me
