@remilia15 I have noticed something. I previous version of Android. When we turn on WiFi hotspot, hostapd change the firmware path.

Nice. My kernel had the config you mentioned enabled already

ngoquang2708 commented 5 years ago

OK. About the firmware path change, have you checked?

diepquynh commented 5 years ago

No, I haven't. What do you have in logcat?

diepquynh commented 5 years ago

I'm think about where does this commit goes https://github.com/LineageOS/android_hardware_libhardware_legacy/commit/1650ddc3f6c0e8e29f8a5639f226358998f49738

Nothing interesting in logcat. But kmsg shows that hostapd start with the same firmware as wpa_supplicant, not the one that for AP mode.

I see that netd's SoftApController is removed.

ngoquang2708 commented 5 years ago

It is used to switch the firmware between AP and STA mode.
