AIROC™ Wi-Fi and Wi-Fi Bluetooth Combos Forum Discussions
We're considering a CYW54590-based wifi/BT module for use in an audio device, and it would be very useful to be able to perform (reasonably) accurate time synchronization between multiple devices. Does the CYW54590 firmware support any mechanism to do so? Support for IEEE 802.1AS (gPTP) clause 12 would be ideal but any other mechanism would be welcome too, even something as basic as the ability to cross-timestamp the TSF timer of the CYW54590 (which is already synced between all devices connected to the same wifi AP) by providing the TSF timestamp of a GPIO pulse.
Show LessHi Sir
we knew that there are two roaming way of 80211r , one is over-the-ds , the other is over-the-air.
Is it possible that disable over-ther-ds , and keep over-the-air function ?

Hi there,
may I ask
1. Does IFX WiFi 2.4G support 18.5dbm power solution?
2. Does IFX BT support apple find my and does it support Android?
Thank you!

Show LessHi,
Jetson Nano kit + cyw5557x AIRROC chip
Jetson is on latest 32.6 package and 4.9 kernel.
I have a working cyw5557x drivers connecting to a SSID [Wireless Router].
searching through the posts, i tried wl monitor 1 command and it does NOT work.
plz let me know if Monitor mode is supported on cyw5557x.
Also where to find new drivers and/or new releases.
Thanks

Greetings,
I am trying to integrate LBEE5PK2AE-564 WiFi/BT module with USB interface (using CYW4373E chipset) with imx8mm (Android) and want to test WiFi/BT in Android,
i have tested the WiFi successfully and now trying to integrate and test Bluetooth, but in order to test the Bluetooth we used a binary (brcm_patchram_plus_usb_64bit) to load the firmware in the Linux but in Android the binary does not work as it is different linker.
For Example:
This is the binary you have provided:
# file brcm_patchram_plus_usb_64bit
brcm_patchram_plus_usb_64bit: ELF shared object, 64-bit LSB arm64, dynamic (/lib/ld-linux-aarch64.so.1), BuildID=403983701e4aaf5728177f1e9b6e91db9354cdd1, not stripped
And this is present in our source for reference architecture:
# file cmd
cmd: ELF shared object, 64-bit LSB arm64, dynamic (/system/bin/linker64), for Android 30, BuildID=f97435a45132606a0c701ed5c1709bd5, stripped
And as you can see the dynamic lib linker is different. And when i execute the binary you have provided(given all permissions), I am getting the following error:
phyboard_polis:/vendor/bin # ./brcm_patchram_plus_usb_64bit
/system/bin/sh: ./brcm_patchram_plus_usb_64bit: No such file or directory
1|phyboard_polis:/vendor/bin #
1|phyboard_polis:/vendor/bin # ls -l brcm_patchram_plus_usb_64bit
-rwxr-xr-x 1 root shell 23840 2024-03-18 06:18 brcm_patchram_plus_usb_64bit
So I tried cross compiling by downloading the source code from GitHub but it throwing error. Please have a look at the error:
$ aarch64-linux-gnu-gcc -o brcm_patchram_plus_usb brcm_patchram_plus_usb.c -lbluetooth
brcm_patchram_plus_usb.c: In function ‘hci_send_cmd_func’:
brcm_patchram_plus_usb.c:311:9: warning: implicit declaration of function ‘writev’; did you mean ‘write’? [-Wimplicit-function-declaration]
while (writev(sock, iv, ivn) < 0) {
^~~~~~
write
/usr/lib/gcc-cross/aarch64-linux-gnu/7/../../../../aarch64-linux-gnu/bin/ld: cannot find -lbluetooth
collect2: error: ld returned 1 exit status
And there is no libbluetooth.so in our toolchain.
I request you to provide us with brcm_patchram_plus_usb_64bit binary which supports Android or please provide us with documentation or procedure to compile for Android or is there any another way to run the binary and flash the firmware.
Thanks.
Show LessHello,
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
Show Less目前平板用cyw43455,同时多台设备测试漫游切换功能,测几百次有个别设备会概率性的断线,驱动版本version 100.10.63 内核4.4,安卓8.1,附件是日志和固件,帮忙看看什么原因,会不会路由器同时处理不了那么多漫游设备,漫游切换的超时时间可以调整吗,漫游功能roam_off功能已经开了。
谢谢
Show LessHow many stations or connections can each WiFi silicon family support without major modifications?
What physical features may affect the number of stations or connections?
- Based on a previous post, available memory plays a role.
- https://community.infineon.com/t5/Wi-Fi-Combo/Looking-for-details-regarding-CYW43455-concurrent-Station-and-AP-operation/td-p/122651
Does Infineon have a table that lists individual capabilities of each WiFi silicon?
- When selecting the base silicon in a radio, understanding I'll be using a partner module, it would be helpful to know any limitations to the number of potential stations or connections.
