CYW920719B2Q40EVB-01开发板上有外置天线的接口，如下图中红圈所示：

请问如果需要连接外置天线，是否需要把C67电容（8.2pF）从位置B移至位置A？除了更改C67电容位置还需要做其他调整吗？

谢谢！

Hi all,

Does anyone know how to append the "PMKID count and List" to the RSN IE in a association packet for the roaming(PMKID caching) in case of the WPA2 EAP-TLS.

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.

Of course,  the STA can join to the AP and leave  works well except the PMKID caching.

Regards,

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 ?

Hi Team,

I could see the mainline has support for brcmfmac driver in the 6.1 kernel. But I couldn't get the wifi up on my device.

I could see that your GitHub firmware was updated up to 5.15.58, could you guys share the updated firmware for 6.1 kernel?

Hi all.

I am trying to setup AP mode for 5GHz with channel 40MHz. Module 2BC from Murata

My config hostapd.conf:

interface=wlan0
ssid=CYW_4373
beacon_int=50
#ctrl_interface=/var/run/hostapd
driver=nl80211

max_num_sta=5
channel=36

wpa=2
wpa_pairwise=CCMP
wpa_passphrase=12345678
wpa_key_mgmt=WPA-PSK

hw_mode=a
ieee80211ac=1

# VHT (Very High Throughput) 40
ht_capab=[HT40+][SHORT-GI-20][SHORT-GI-40]
vht_oper_chwidth=0

wmm_enabled=1

when I try to start hostapd, the point does not rise
What could be the reason?

Hi,

I was trying to cross compile the cypress-fmac driver for my Ambarella S3L platform.

I prepared the .config with this command:-

make -b KLIB=$MY_KERNEL KLIB_BUILD=$MY_KERNEL CROSS_COMPILE=/usr/local/linaro-armv7ahf-2017.08-gcc7.1/bin/arm-linux-gnueabihf- defconfig-brcmfmac

I executed the build with this command:-

make -b KLIB=$MY_KERNEL KLIB_BUILD=$MY_KERNEL ARCH=arm CROSS_COMPILE=/usr/local/linaro-armv7ahf-2017.08-gcc7.1/bin/arm-linux-gnueabihf- modules

Note that, MY_KERNEL is pointing to the installed SDK linux folder /kernel/linux-3.10_s3l.

However, I encountered this kind of errors:-

<TOPDIR>/v5.15.58-backports/include/linux/list.h:308:2: error: implicit declaration of function ‘smp_store_release’; did you mean ‘__release’? [-Werror=implicit-function-declaration]
smp_store_release(&entry->next, entry);

<TOPDIR>/v5.15.58-backports/include/linux/list.h:326:27: error: implicit declaration of function ‘smp_load_acquire’; did you mean ‘__acquire’? [-Werror=implicit-function-declaration]
struct list_head *next = smp_load_acquire(&head->next);

<TOPDIR>/v5.15.58-backports/backport-include/linux/time.h:5:10: fatal error: linux/time64.h: No such file or directory
#include <linux/time64.h>
cc1: some warnings being treated as errors
compilation terminated.

Is there any patches required to fix this? The kernel in this instance is v3.10

Thank you.

Which models of BLE Mesh or Matter does Combo currently support, thank you

Hi,

I am using Wiced 6.6 for one of our exiting BLE based application. The  CYW4343 wifi-Bluetooth combo module is used in this product. I have configured the device is as server.

while performing simple read operation of 10 bytes by Client it takes more than 100 msec, even though there is no application code added.  it reads from BLE stack Gatt layer. I have performed this experiment using more than one client like nRF Connect. I would like to increase the speed for Gatt read and write operation. I am using MTU size 512.

Please throw some light on this.

NOTE:

I know, it is recommended to use Modus Tool Box for new designs, However this is exiting produce where already wiced6.6 had used.

Regards,

Lokraj
