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

工程师你好！我的问题是这样的，我用你们的开发板CY943907AEVAL1F 可以下载程序，这个开发板上用了USB转JTAG芯片FT2232HQ-TRAY，我们的产品不需要这个芯片，我们想直接用JTAG下载工具连接到LBWA1UZ1GC上下载。现在在这个步骤遇到了困难，不知道开发软件需要怎么设置？请问有相关文档供参考吗？谢谢。

I would like to know API for 802.11k and 802.11r for STM32 Expansion pack with CYW4373 like a wwd_wifi_radio_resource_management_beacon_req on wwd_wifi.c in WICED Studio.

Because I think WICED Studio is not recommended now.

Environment:

STM32H747I-DISCO+EAR00388

Best Regards,

Tsutsumi

I have fast data >200Mbps to be sent out to a Wifi access point.

The protocol of this fast data is SLVS.  So I would use an FPGA to convert from SLVS to USB2.0.

This FPGA shall then be interfaced to the CYW54907 USB2.0 port and transmitted over Wifi.

1) Do you see any issue with this setup configuration to the USB2.0 port of the CYW54907?

2) What is the typical throughput speed will I expect going from USB2.0 to Wifi over the air (assume the environment is clean from other radio sources)?    Will I be able to reach >200Mbps over the air with the CYW54907?

During the project, I need to create equipment that can be updated wirelessly using WiFi. So far, the MCU has been implemented to connect to the router. Is it possible to implement the Serial Bridge for Uart using wifi with the cyw43439chip?

My setup:

- ARM host processor running 5.15.67 Linux. 

- Murata 1MW BT/Wi-Fi combo chip (BCM43455) over SDIO using OOB wakeup

- Wi-Fi firmware: version 7.45.265

- Using linux/hostapd patch sets from "cypress-fmac-v5.15.58-2023_0901"

Problem Summary:

My issue is that when I enable Wi-Fi on my board, Bluetooth audio performance becomes extremely poor - full of cracks and pops.

Extensive testing has shown that this issue occurs after a specific sequence of events:

1. Power on the board
2. modprobe brcmfmac
3. Start Bluetooth stack, connect to a headset device using HSP and establish SCO connection
4. Now, start wpa_supplicant and scan/connect to a 2.4 GHz AP - Audio distortion begins during scan.

Additional details:

I have already enabled some coexistence parameters in the NVRAM file:

btc_mode=1
btc_params8=0x4e20
btc_params1=0x7530
btc_params50=0x972c

The problem occurs with or without these parameters.

Also, I notice that if I remove the brcmfmac module and re-insert it between steps 3 and 4 above, the problem seems to go away, or at least become much less likely. 

Possibly related issue:

My suspicion is that the 43455 is entering a state like it was in my other post from a couple years ago

Removing brcmfmac module impacts Bluetooth audio... 

I have not tested to see if the above issue still exists. I have been avoiding module removal as a workaround. 

Would Infineon be willing to investigate this issue?

When i reboot mcu with cyw43439(Laird sterling lwb-plus), my ble chips not working.

but my mcu system reset 5~10 times it work okay.

Can you please guide if CYW4343W support Hands free profile so that we can use it in smartwatch to transfer phone call from mobile phone to smartwatch over Bluetooth ?
