Does CYW54591 support ACS feature?

[NickDing]

Hi IFX team,
I have one question about ACS (Automatic Channel Select) feature on Type1XZ (CYW54591).

I found that our NB can’t find Wi-Fi AP after setting channel=0 in hostapd.conf.

Although I found that there is a similar question about ACS feature on another topic, it’s related to Type1MW (CYW43455), not exactly the same IC.

(https://community.infineon.com/t5/Wi-Fi-Bluetooth-for-Linux/how-to-make-acs-automatic-channel-select...)

Therefore, I’m wondering whether CYW54591 have the same condition as CYW43455 that ACS is not supported in WLAN FW?

Could you help me to check?

Thank you.

Hi,

CYW54591 supports ACS functionality. What is the firmware version in your setup? Can you provide the firmware(.bin file)?

Thanks

Hi Aditi,

Thanks for your prompt reply.

We already tested this latest FW before, but it still failed to test ACS.

Detailed test information is below.

P.S. The hostapd has enabled the CONFIG_ACS configuration.

• Test channel acs_survey logs as the attached file, “V5.15.58_channel_acs_survey_0321.logs”
  Line 383, vi hostapd.conf
  Line 401, start WiFi AP
  Line 428, Turn on WiFi AP Success.
  Line 434, ifconfig
  Line 539, ps without hostapd
  Line 556, restart WiFi AP
  Line 628, ps without hostapd
• Test channel 0 logs as the attached file, “V5.15.58_channel0_0321.logs”
  Line 331, start WiFi AP
  Line 359, Turn on WiFi AP Success.
  Line 427, ps without hostapd
  Line 443, restart WiFi AP
  Line 521, ps without hostap
  Line 525, ifconfig
  Line 568, WiFi FW version
  Line 586, vi hostapd.conf

Best regards,

Hi Aditi,

Thanks for your support.

May I know is there any update regarding to this topic?

Should I issue a case of it to trace the progress?

Best regard,

Nick
