Dear everyone

Customer need to build the CYW20707 footprint, but they found the pin name is different from Ball Map.
Because customer request two part need to be consistent.
Will Infineon revise the document?
Or can customer use Ball Map name as a focus first?

The difference list as attached file.

Thank you.

In the LE GATT Server Throughput Example, I found that the size of each notify array is 244u. I want to know if the maximum size of the notify data is 244 arrays. Because I want to notify 512 or 1024 each time to reduce the pressure on my streambuffer in FreeRtos. If notify supports arrays with a notification size greater than 244 each time, what modifications do I need to make to achieve arrays with a notification size of 512 or 1024 each time.

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?

In this specific situation, wpa_supplicant (wpa_cli) is used when the device which has CYW43455 1MW  chip is in normal mode. When the device goes to deep sleep( linux  goes suspend to RAM mode) 1MW chip goes to power-save mode.

My question is when the device is in the state above, can we use internal supplicant  to offload gtk rekeying ? And is it possible that when the device is back to normal state to external and internal supplicant are used simultaneously?

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

Hi Communties,

I have questions about IFW56810(The AIROC™ Cloud Connectivity Manager (CCM) modules).

https://www.infineon.com/cms/jp/product/wireless-connectivity/airoc-cloud-connectivity-manager/

According to the ProductBrief and DataSheet, I guess this module is not certified for Japan.
When we want to use this module in Japan, how can we deal with certification?
Can we request Infineon to do the certification work?
Or do we need to do the certification work by ourselves?

Best Regards,

Hi Sir:

Does below linux BT SDK has Bluetooth SIG DID/QDID???

Thanks.

HI,

We were testing the BLE functionality with Android9 OS.

During testing we found that BLE connection failed with the error showing  "bt_smp : dhkey chcks do no match".

This is random issue and observed during paring and unpairing. while performing this exercise we observed the dhkey mismatch error after 10 iteration of paring and unpairing..

Could please help on this.

Thanks,

Rajendra
