STEP 1 - OPEN HOTSPOT
normally by pulling qs down
to start swlan0 interface

STEP 2 - INITIALIZE ADDRESS
su -c ip address add 1.1.1.1 dev swlan0

STEP 3 - INSTALL AND RUN SS

to /sdcard/SSCapture/ok2.png

STEP 4 - GET SSCaptureEye
paste to /sdcard/DCIM
where SSCapture folder is

STEP 5 - RUN A PYTHON SERVER
cd /sdcard/DCIM
python3 -m http.server -b 1.1.1.1 1111
