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

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!

Hi, 

I am using CYW43455, information about my firmware is as follows:
wl0: Aug 29 2023 01:47:08 version 7.45.265 (28bca26 CY) FWID 01-b677b91b

I have noticed a change in "wl wowl_wakeind" response. I am interested in these 3 wake conditions:

• wake up on magic packet
• wake up on disconnect
• wake up on loss of beacon

In older firmware that I have been using until recently (wl0: Apr 15 2021 03:03:20 version 7.45.234 (4ca95bb CY) FWID 01-996384e2) I had the following messages as response, respectively:

• "MAGIC packet received"
• "Disassociation/Deauth received"
• "Beacons Lost"

Currently, as a response to "wl wowl_wakeind" I don't get any of those messages, just the following codes, respectively:

• 32769 (0x8001)
• 4
• 16 (0x10)

I would say that these codes correspond to the bitmap (found here: https://community.infineon.com/t5/Knowledge-Base-Articles/Wake-on-WLAN-with-43455/ta-p/246041):

Current bitmap for wowl
#define WL_WOWL_MAGIC (1 << 0)                     /* Wakeup on Magic packet */
#define WL_WOWL_NET (1 << 1)                          /* Wakeup on Netpattern */
#define WL_WOWL_DIS (1 << 2)                           /* Wakeup on loss-of-link due to Disassoc/Deauth */
#define WL_WOWL_BCN (1 << 4)                        /* Wakeup on loss of beacon */
#define WL_WOWL_GTK_FAILURE (1 << 10)      /* enable wakeup if GTK fails */

Although I am not sure what the bit 1<<15 represents (0x8000) in my wake on magic packet event (0x8001).

Is there any API that can get me the old response format for "wl wowl_wakeind"? 
Could you please provide documentation regarding these changes?

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

Hi,

I would like to find out if it's possible to maintain a connection to an SSID while my Linux host is suspended.

Based on this document, https://www.infineon.com/dgdl/Infineon-AN227910_Low-power_system_design_with_AIROC_CYW43012_Wi-Fi_%26_Bluetooth_combo_chip_and_PSoC_6_MCU-ApplicationNotes-v03_00-EN.pdf?fileId=8ac78c8c7cdc391c017d0d39b66166f3, does the host offload occurs in this case?

If so, how do I test this using my Linux host? I'm using Ambarella S3lm as my SoC.

Thank you.
