android enable disable bluetooth via command line

问题:

I am trying to enable disable bluetooth on android device using command line.

I can enable it using

adb shell am start -a android.bluetooth.adapter.action.REQUEST_ENABLE

But it prompts user to 'allow' or 'deny'.

I also see there is option to launch ble settings first like

adb shell am start -a android.settings.BLUETOOTH_SETTINGS

and then enable disable adb shell input keyevent **

But it won't be device independent.
