I have a rooted galaxy S2(I9100) and was wondering if I can restart the bluetooth on my phone via the terminal client on my phone.

Thanks.

The following terminal command should enable Bluetooth via adb shell or Terminal Emulator app:

su
am start -a android.bluetooth.adapter.action.REQUEST_ENABLE

On most versions of Android, this command will present a pop-up window to the user asking to confirm request to enable BT. I believe this was done for security purposes whenever an app that is not system is toggling BT.

I haven't found a way to disable BT via a shell command unfortunately.

With WiFi it's a lot easier, and does not prompt user for permission:

su
svc wifi enable

will turn it on, and 

su
svc wifi disable

will turn it off.

Thanks for the answer. I'll try the same. Could you also list the same for WiFi? – Clyde Lobo Apr 5 '12 at 9:43
Edited my answer with the WiFi info. I haven't found a way to disable BT via a terminal command though :( – Chahk Apr 5 '12 at 12:42
