Hi all, I've also submitted this question to stackoverflow here: https://stackoverflow.com/questions/59613445/wpa-supplicant-sync-channels-between-two-wireless-virtual-interfaces, but since I suspect answering it needs a pretty deep understanding of wpa_supplicant internals, I'm also sending it into the mailing list. I'm working with a raspberry pi with a stripped down distro - NARD (http://www.arbetsmyra.dyndns.org/nard/), and I would like to use two virtual wireless interfaces, one running in AP mode (service network) and the other connecting to a wireless network. The chip supports this, but ONLY if they are on the same channel. I've been pulling my hair out over this for the last couple of months, because it was only connecting to **SOME** (read - those on channel 6) networks due to this... My question would be if wpa_supplicant is capable of setting the channel of the `ap0` interface based on which channel the `wlan0` interface wishes to connect to? Simply removing the frequency stanza from the configuration of the `ap0` interface makes it choose one automatically, but does not sync to the one used by the `wlan0` interface. My current setup looks like this: ``` /usr/sbin/wpa_supplicant -i ap0 -c /etc/wpa_supplicant_ap0.conf -D nl80211 -N -i wlan0 -c /etc/wpa_supplicant.conf -D nl80211 -P /var/run/wpa_supplicant.pid -B -s ``` /etc/wpa_supplicant_ap0.conf ``` ctrl_interface=/var/run/wpa_supplicant # Scan for accesspoints regularly ap_scan=1 autoscan=periodic:120 ignore_old_scan_res=1 bgscan="simple:60:-45:240" # Enable Protected Management Frames pmf=1 network={ ssid="<snip>-setup" mode=2 key_mgmt=WPA-PSK psk="<snip>" frequency=2437 } ``` /etc/wpa_supplicant.conf ``` ctrl_interface=/var/run/wpa_supplicant update_config=1 pmf=1 ignore_old_scan_res=1 bgscan="simple:60:-45:240" autoscan=periodic:120 network={ ssid="<snip>" psk="<snip>" priority=10 ap_max_inactivity=60 } network={ ssid="<snip>" psk="<snip>" priority=20 ap_max_inactivity=60 } ``` Regards, Akos Vandra _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
