The customer is considering either the CYW4373 or CYW54591, but since the end customer uses Android, they want to implement Fluoride. Are these parts compatible with Fluoride?
Show LessHi,
I'm trying to optimize power consumption on our board based on the cyw43907 dev kit. Our device will typically hibernate for a few hours, connect to a server for a few seconds and go back to hibernate. The setup time/consumption when waking up from hibernate is thus important.
I'm measuring peak current of ~700mA when connecting to wifi.
Can we reduce the peak consumption (at a small cost to emission power)? I tried to set wwd_wifi_set_tx_power to 20 instead of the default 31, but it did not change the current.
Thanks,
Cédric

Hi guys,
Would you please inform if the WPA3 enterprise security 192bit mode can work by using the "Enterprise-security" software ?
The link is
https://github.com/Infineon/enterprise-security
I've developing the WPA3 several client mode using the Infineon's Enterprise-Security and the Airoc-wifi-Bluetooth-STM32.
The EAP-TLS and the EAP-PEAP have been worked correctly but the 192bit mode can not worked.
Thanks,

I'm working with CYW954907AEVAL1F to measure the maximum speed of WiFi and USB. My eventual goal is to move data from WiFi to CDC ACM. I measured WiFi speed using the built in iperf function and it reached 200Mbps on a 80Mhz channel, which is great. I then measured top speed of CDC ACM using some custom client side code on Windows and a modified version of the cdc_acm_read_write sample. The modification just writes bytes to CDC ACM in a loop (see below).
Default parameters yielded transfer rate of 40Mbps. Increasing MAX_CDC_ACM_BUFFER_SIZE to 4096 improved it to 47Mbps. Then I implemented a custom version of ux_device_class_cdc_acm_write which doesn't copy memory and doesn't lock mutex, and that got me 62Mbps. It's still a bit far from my goal of 100-200Mpbs. Is this device capable of such speed? What else can I do to increase transfer rate over USB?
while (1) {
ux_device_class_cdc_acm_write(cdc_acm, cdc_acm_buffer, MAX_CDC_ACM_BUFFER_SIZE, &actual_length);
}

Hi team,
Could you let me know if the CYW4373 (Murata 2AE module) supports Wi-Fi Enhanced Open (OWE) ?
Operation is as the STA.
The firmware and the CLM is as follows:

Show LessHello,
I am trying to run
https://github.com/Infineon/AIROC-Wi-Fi-Bluetooth-STM32
with a combination of SONA IF573 and STM32MP135.
I know that the package does not support Cortex A7 solutions, but I believe, it is not impossible to apply the driver.
I am using Azure RTOS and I am trying to reimplement wifi-netxuduo examples of STM32H747I.
For now I am stuck at the bus initialization of
In detail, after downloading a nvram image, I get a timeout error.
I am sure my wifi_nvram_image.h is proper. It might be a problem of the SDIO clock configuration.
I have measured the frequency and it is 32 MHz. It is being set by the driver itself at some point of initialization.
Would you have any ideas what might be the problem?
Aditionally, I couldn't find a reference manual for CYW55573. It would be always helpful to get one.
Best,
J. Schneider
Show LessI'm trying to use the application processor in CYW954907AEVAL1F to act as a USB device. There are good examples in WICED Studio, but Wiced Studio only supports a limited set of USB classes. I asked this question and got an answer that WICED studio is discontinued in favor of ModusToolbox. I can't find any USB examples in ModusToolbox which could help kicktstart USB development with CYW954907AEVAL1F. Please help.
Show LessI'm looking for the latest datasheet for the CYW4373. There is an attachment to the post at https://community.infineon.com/t5/AIROC-Wi-Fi-and-Wi-Fi-Bluetooth/CYW4373-datasheet/m-p/501774#M2775 but it's marked as 'preliminary'. The product page has no datasheet file. Is there an official version of this datasheet?
