How can I control my Android device from a windows PC though a HotSpot. I mean there's no Internet, no LAN and no USB between PC and Android. I'm looking for something like ShareIt, but for mirroring android screen and controlling it via PC mouse.
try TeamViewer. its a good remote control app from PC to PC and phone to PC and PC to phone.
try AirDroid its good and it worked for me.
If you need just simple commands(enter text, press, perform actions):
adb shell input
text, keyevent, keyboard, mouse, joystick, touchpad, trackball, dpad and more.
adb shell input text "Hello"
