I'm working on MT7688 board (HiLink) which is almost the same as LinkItSmart7688.
I need to get AP and STA independent configuration on my device. I need to have STA Wifi to be conected to the device (like camera or printer or etc.) and AP to be connected by the phone or PC for the administration.
Problem is that in APSTA mode, the AP is active only if STA is connected. Once STA is disconnected, AP will disappear.
I have tried many OpenWRT versions with original proprietal wifi driver and also many versions of new OpenWRT with MT76 driver, all works same way.
My latest wireless settings:
config wifi-device 'radio0' option type 'mac80211' option hwmode '11g' option path 'platform/10300000.wmac' option htmode 'HT20' option disabled '0' option channel 'auto' config wifi-iface 'default_radio0' option device 'radio0' option network 'lan' option mode 'ap' option ssid 'SmartBox' option encryption 'none' config wifi-iface option ssid '5A' option bssid '2C:4D:54:B4:B3:A8' option device 'radio0' option mode 'sta' option encryption 'psk2' option key 'xxxxxxx' option network 'wwan'
