Wi-Fi Combo

Environment and SDK information:
WICED version: 6.4
Wi-Fi Module: Murata Type1GC

Wi-Fi connection(to wireless LAN AP) is lost immediately after 11 hours past with WPA3-SAE.
We think it was caused due to Wi-Fi module is down. It's not disconnected by wireless AP.
And we have already tried other wireless LAN AP from several vendors, and we confirmed that the same issue was reproduced in every case.
However, if we choose WPA2-PSK, the issue doesn't happen. Wi-Fi connection is still alive after 11 hours past.

Do you have any solutions to this issue?

Hello, I'm using CYW954907AEVAL1F.

I develop an app that listen and accept incoming TCP connections on WiFi.

Sometimes when I create socket I obtain error

result = 7

Hello,

I'm using CYW954907AEVAL1F to send WiFi UDP packets larger than 1KByte at a rate of 30x2Packets/s.

I'm using wiced_packet_create_tcp API and sometimes it fails : it returns 2 (TIMEOUT)

I run debugger and I see this situation ...

Can someone help me ?

Hi,

With WICED_ENABLE_MCU_RTC, I would expect after setting RTC time and reboot

then I can still get correct rtc time.

However, I found platform_rtc_init will always setting the rtc time to default_rtc_time during boot.

As a result, everytime reboot the device, the rtc time is wrong.

Note, all support platforms has such behavior - always setting the rtc time to default_rtc_time during boot.

Can someone explain this?

Hello,

When could we expect support for the LwIP Chained Buffers?

At the moment, Wiced does not properly support LwIP without this. The Chained Buffers are a core feature of LwIP which cannot be deactivated.

My previous post was closed as Solved but the issue itself is not: https://community.infineon.com/t5/Wi-Fi-Combo/low-level-output-asserting-with-quot-No-chained-buffers-quot/td-p/272447

Thanks for your support,

Best regards

The comment says it's a known issue and will update the thread when the fix is available.
However, that thread never get updated.

I'm wondering if this is still an issue in latest sdk or not.

BTW, I have no idea why that topic get locked before updating the fix.

We are looking for some information on rough memory footprint data on simultaneous BLE/WLAN examples - using the ST+Cypress part (LBEE5PA1LD).  Some things to note:

WLAN in STA or AP mode? (we would need both in the FW, but not simultaneously)
BLE peripheral
Are there some documents out there, or possibly examples we could use for a guestimate?  I did find N1-4945_Type1LD-AppNote_Memory_Usage.pdf appnote, which looks like it is the https_server example, but the footprint data isn't broken down to a level that is meaningful from the question "How much space does the WLAN host stack/driver and BLE (HCI) host stack/driver take up?

The WICED-6.6.1.1 is using mbedTLS-2.16.6, which includes some security issues:

Please upgrade mbedTLS to the latest stable version.
