Bluetooth command commands for ADB

Question

I am currently studying automation for testing a Bluetooth connection between an android phone and another device.

I have found many useful ADB commands, such as

• adb shell service call bluetooth_manager 6
• adb shell am start -a android.bluetooth.adapter.action.REQUEST_ENABLE
• adb shell am start -a android.bluetooth.adapter.action.REQUEST_DISCOVERABLE
• adb shell service call bluetooth_manager 8

but could not find anything for the following actions:

• Scan for detected Bluetooth devices
• Pair with this detected Bluetooth device.
• Forget about an earlier paired Bluetooth device.
• Connect to an earlier paired Bluetooth device.
• Disconnect from an earlier paired Bluetooth device.

Are there any Or do I need to write an Android wrapper application that can do this?
