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

Hello,

We are using CYW43455 and its godzilla release on linux 5.15.71. Occasionally, when device comes back from deep sleep, CYW43455 shows its connected ( RSSI is being changed when getting closer or further to AP), IP address is there, but the network data doesn't come through. In addition it looks like that Rx counter showed in output of ifconfig command doesn't change when CYW43455 is in this state.

Can you please help solving this issue ? Is this a known issue, is there a patch for it ? Or we would need to come up with mechanism to detect this state and then try some recovery steps (reconnect, interface down/up, reassociate)?

Thanks,

Bogdan

Hello. What is the maximum data rate on an SDIO interface between an stm32h753vi and the CYW55573 (Murata Type 2EA)? 

Hi all,

I am trying to confirm a STA mode for the 5GHz 144ch(5720MHz) with channel width=20MHz
but I can't access to a AP.
I've used the AIROC-Wi-Fi-Bluetooth-STM32 Expansion Pack 1.5.0 with Enterprise-security V2.1.0 from GitHub on STM32H747DISCO + Murata 2AE(CYW4373) board as a STA.

I've confirm the source code.
I found if the symbol "CY_WIFI_COUNTRY" is defined to "WHD_COUNTRY_JAPAN", it can NOT access to a AP.
If defined the "CY_WIFI_COUNTRY" to "WHD_COUNTRY_UNITED_STATES", it CAN access to a AP.
After July.2019, the 144ch of the W56 has been expand(accessed) in Japan and I think the WLAN firmware has been not supported above the expansion.

WLAN firmware version is as follows:
"WLAN Firmware : wl0: Aug 1 2023 00:41:38 version 13.10.246.321 (ebd095c CY) FWID 01-1c9488f8"

Does anyone know how to resolve this issue ?

Regards,
