android enable disable bluetooth via command line

Question

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.ac

Answer 1

As awm129 has pointed out, solutions using service call aren't device-independent. While I am unable to completely eliminate the use of service call, the following solution should be more device-independent:

To disable:

pm disable com.android.bluetooth

To enable:

pm enable com.android.bluetooth
service call bluetooth_manager 6

I hope someone will eventually find a service call-free solution.

Answer 2

To run commands listed in previous comment, you need to be root:

adb root

Enable:

adb shell service call bluetooth_manager 6

Disable:

adb shell service call bluetooth_manager 8

Answer 3

To enable:

adb shell service call bluetooth_manager 6

To disable:

adb shell service call bluetooth_manager 8

Answer 4

On Xiaomi Mi 4i / MIUI 9:

To enable:

adb shell service call bluetooth_manager 8

To disable:

adb shell service call bluetooth_manager 10

This can also run within Andorid like:

service call bluetooth_manager 10

Answer 5

I do not have enough reputation points to add a comment so I am following up on TripeHound's comment on wuseman's answer.

I tried TripeHound's way of setting the Bluetooth global setting (

adb shell settings put global bluetooth_on 1

) on a Samsung Galaxy Tab A (SAMSUNG SM-T515 running Android 10, Kernel 4.4.177) and it does indeed seem to work. However, the Bluetooth icon will not show the change when opening the quick-settings menu nor will it show the change when you go to the full settings menu.

That said, if I restart the tablet immediately after it will indeed reboot with the correct state so I am not sure whether it is necessary to re-read the global settings somehow to ensure that the Bluetooth radio is actually off.

Comments appreciated!

For bluetooth status:

adb shell settings get global bluetooth_on 

or

adb shell settings list global |grep ^bluetooth_on

Enable Bluetooth

adb shell settings put global bluetooth_on 1

Disable Bluetooth

adb shell settings put global bluetooth_on 0

Via am - Instead of request, use enable

adb shell am broadcast -a android.intent.action.BLUETOOTH_ENABLE --ez state true

Via Keyevents

adb shell am start -a android.settings.BLUETOOTH_SETTINGS 
adb shell input keyevent 19
adb shell input keyevent 23

Edit 2019-06-22:

Finally figured out a way to toggle bluetooth on/off on Android 8.0 and newer versions without root, "bluetooth_on" doesn't seems to work on latest android versions anymore:

Enable Bluetooth - No root required

  adb shell settings put global bluetooth_disabled_profiles 1 

Disable Bluetooth - No root required

  adb shell settings put global bluetooth_disabled_profiles 0

And since above works fine then of course content works fine aswell:

Enable Bluetooth - No root required

 adb shell content insert --uri content://settings/global --bind name:s:bluetooth_disabled_profiles --bind value:s:1 --user 0 

Disable Bluetooth - No root required:

 adb shell content insert --uri content://settings/global --bind name:s:bluetooth_disabled_profiles --bind value:s:0 --user 0
