AIROC™ Wi-Fi and Wi-Fi Bluetooth Combos Forum Discussions
During the project, I need to create equipment that can be updated wirelessly using WiFi. So far, the MCU has been implemented to connect to the router. Is it possible to implement the ota upgrade with the cyw43439chip?
Show LessI would like to know API for 802.11k and 802.11r for STM32 Expansion pack with CYW4373 like a wwd_wifi_radio_resource_management_beacon_req on wwd_wifi.c in WICED Studio.
Because I think WICED Studio is not recommended now.
Environment:
STM32H747I-DISCO+EAR00388
Best Regards,
Tsutsumi
Show LessHello
I'm looking into the specifications of the wireless LAN chip CYW55573, but I don't know the following characteristics, so I would like to know
1.RF output (dBm at6GHz MCS11/80MHz to MCS0/20MHz)
2. Receiver sensitivity (dBm at6GHz MCS11/80MHz to MCS0/20MHz)
3.power consumption (W at6GHz MCS11/80MHz to MCS0/20MHz)
If you have a detailed product data sheet that lists these characteristics, please attach a file or link.

Show LessWhen i porting wifi_join_wpa3, but I'm get a "Failed to initializze Wi-Fi".
So i'm check problem point. then, i find stop point.
whd_management.c in, whd_management_wifi_platform_init
could you please let me know the procedure for adaptivity test in detail for 1MW chip?
Hello. I am wondering if the NUCLEO-H753ZI board can be used according to the https://github.com/Infineon/AIROC-Wi-Fi-Bluetooth-STM32/tree/master and if there are any example projects for its use. Furthermore, what other boards do I need concerning the MuRata Type 2EA, for example, a MuRata Nucleo adapter board to work with the NUCLEO-H753ZI?
Thank you
Show LessAttached is a high level overview on Wi-Fi SKU planning and addressing world-wide regulatory compliance.
Details and further information can be found in “Infineon Wi-Fi CLM Regulatory manual” AN225347.
We're using a custom board with the CYW43455 module, and we're using concurrent STA and AP mode as explained here:
https://community.infineon.com/t5/Resource-Library/Concurrent-AP-and-STA/ta-p/246043
So, STA mode (wlan0) is using wpa_supplicant and AP mode (wlan1) is using hostapd.
The regulatory domain is set to the Netherlands. This has been done with 'iw reg set NL' and 'wl country NL'. Our CLM_blob contains the proper regulatory domain settings for NL/ETSI.
Everything seems to work well unless a 5G DFS enabled channel is used.
If a DFS enabled channel is used the STA mode fails after a while. We can see the failure occuring once these kernel error messages start to appear:
[209319.907996] ieee80211 phy0: brcmf_run_escan: error (-52)
[209319.913577] ieee80211 phy0: brcmf_cfg80211_scan: scan error (-52)
[209320.938726] ieee80211 phy0: brcmf_run_escan: error (-52)
[209320.944251] ieee80211 phy0: brcmf_cfg80211_scan: scan error (-52)
It looks like the wifi firmware somehow (partly) fails and always rejects scan requests (brcmf_run_escan talks to the wifi firmware via fil/sdio).
Actually, the problem is already there if the STA is on a DFS-enabled channel and we're forcing a disconnect and reassociate with: 'wpa_cli -iwlan0 disconnect' and 'wpa_cli -iwlan0 reconnect'.
We've tried several things to avoid this issue, I'm talking about:
- disable power_save with 'wl pm 0' and/or 'iw wlan0|1 set power_save off'
- use latest wifi FW image (BCM4345/6 wl0: Apr 15 2021 03:03:20 version 7.45.234)
- disable DFS with 'wl dfs_ism_monitor 1', 'wl radar 0' and 'wl dfs_preism 0'
But it doesn't help.
By enabling the appropriate brcmfmac debug options (and debugfs) we could get the "brcmfmac forensics". The following errors pop up:
000111.394 wl0: wlc_iovar_op: escan BCME -43 (Scan Rejected)
000111.394 wl0: wlc_scan_request_ex, can not scan due to error -43
000112.434 wl0: wlc_iovar_op: escan BCME -43 (Scan Rejected)
000112.434 wl0: wlc_scan_request_ex, can not scan due to error -43
for more details, see attachment.
Is this a wifi FW issue?
whatever this is, please help us.
If there's no (immediate) solution, a workaround (other than disable 5g) would be good as well.
Thanks!
如果使用我们WiFi6平台开发IPC,但是在IPC需要以太网接口和PoE功能,请问有什么方案介绍吗?
