iMX6UL and Murata 1FX scan in AP mode

I'm using wpa_supplicant to create an ACCESS POINT:

wpa_supplicant -D nl80211 -i wlan0 -c /etc/wpa_supplicant_ap.conf

The problem is that when the device is configured in Access point, i'm not allowed to scan networks:

iw dev   wlan0 scan command failed: Invalid argument (-22)

or in wpa_cli:

> scan OK <3>CTRL-EVENT-SCAN-FAILED ret=-22

In dmesg:

[85769.193376] CFG80211-ERROR) __wl_cfg80211_scan : Invalid Scan Command at SoftAP mode [85769.200133] CFG80211-ERROR) wl_cfg80211_scan : scan error (-22)

and seems that inside wl_cfg80211.c:

if (dhd->op_mode & DHD_FLAG_HOSTAP_MODE) {         WL_ERR(("Invalid Scan Command at SoftAP mode\n"));         return -EINVAL;     }

In the Type 1FX description, it says:

  • Network Topology: AP & STA dual mode

So the problem is that if the wifi is in HOSTAP, the scan is not allowed. Any solution?
