Hi

Our product is working on imx6u platform and wifi module is 1mw, the wifi is working fine when I specify a channel no. like 1 or 11 in hostapd.conf, but I encounted a problem when configuring acs in hostapd.conf.

The embedded linux version is 4.19, and hostapd version is 2.6.

Hostapd is built with CONFIG_ACS.

and I tried both channel=0 or channel=acs_survey.

But I always get the same error message in the log file, "No survey data received. ACS: unable to collect survey data", and then wlan0: AP-DISABLED.

Do you have any suggestions for thie issue?

 

Thanks a lot.

ACS is not supported in the WLAN firmware of 43455, that is why it is failing in your setup.

Does the WLAN firmware of 43438 support ACS?

43438 does not support ACS due to limited memory. 43455 is in maintenance mode and there is no future plan to support ACS.
