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?

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,

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,

Hello

I'm using a le_hello client app, and I'm curious about the consistency of advertising intervals.
Currently, the scan settings are high_duty_scan_interval 320, high_duty_scan_window 160, and high_duty_scan_duration 0.
The advertising settings are low_duty_min_interval 2048, low_duty_max_interval 2048, and low_duty_duration 0.
The mode in use is BTM_BLE_ADVERT_UNDIRECTED_LOW for advertising and BTM_BLE_SCAN_TYPE_HIGH_DUTY for scanning.

When I measured the scan list with NRF Scanner, most items are displayed at 1.28-second intervals, but there are cases where the advertising interval becomes 8 seconds. I'm curious if the advertising is consistently displayed at 1.28-second intervals, and if not, if it's related to scanning. Also, how can I check the advertising interval?
If you have any related documents or code examples, I would appreciate it if you could share them.

Hi Community,

We are testing Bluetooth Radio Receive on Infineon chip CYW54591 by the steps provided from the below document:

https://www.infineon.com/dgdl/Infineon-ModusToolbox_WICED_Manufacturing_Bluetooth_Test_Tool-Software-v01_00-EN.pdf?fileId=8ac78c8c7e7124d1017e9149d76c1593

1. Installed ModusToolbox

2. Created an empty application project (haven't downloaded to the device).

3. Ran the wmbt tool from: "C:\Users\<username>\mtw\mtb_shared\wiced_btsdk\tools\btsdk-utils\<branch>\wmbt".

4. Below are the commands we used to test  Bluetooth Radio Receive. But we couldn't get any statistics report as the document claimed "The WMBT reports connectionless Rx Test statistics every second."

May I know how to get the Rx Test statistics report? Thank you
