Where is wifi driver module file?
#2

I would imagine that it is not an often tested feature, since the wifi would normally be used to obtain the network connection and would therefore be unavailable for use as an access point.

#3

The case is when the user has a sim card, and can connect to 4G data, he can set the phone as hotspot, then connect, for example, his laptop to the phone, then connect to internet.

#4

I didn’t say there was no use case for it. I said that very few people are likely to be using it in that manner, and therefore the chance of detecting the bug will be low.

I would suggest trying to build AOSP from an older known good manifest to try to narrow down when the bug appeared, or if it’s always been there.

Hi all,

Facing similar issue, but root cause might be different.
Unable to turn on hotspot from UI, getting below error :

04-24 22:58:36.957 2685 2783 E HostapdHal: Registering IHostapd service ready callback.

04-24 22:58:41.989 2685 2783 E SoftApManager: setup failure when creating ap interface.

I have already registered hostapd service in init.rc :
service hostapd /system/vendor/bin/hw/hostapd
-e /data/misc/wifi/entropy.bin -c /data/misc/wifi/hostapd.conf -dddddddt
interface android.hardware.wifi.hostapd@1.0::IHostapd default
interface android.hardware.wifi.hostapd@1.1::IHostapd default
socket wpa_wlan0 dgram 660 wifi wifi
class main
disabled
oneshot

But still ServiceManager is unable to fetch IHostapd.getService().
Can someone please guide me on this.

Thanks in advance,
Abhilasha
