Turning off bluetooth on exit.

[ardhuru]

Hi,

In the new serial tutorial by Erel, the bluetooth adapter comes on automatically, if its not on already, when the program is launched.

My question is, can it also be disabled automatically when the program exits (application is closed)?

Regards,

Anand

You can use Activity_Pause (when UserClosed = True) to close the adapter.

Please forgive my amateurish questions, but do I just insert the string in the bracket in the Activity_Pause sub?

I changed

Sub Activity_Pause (UserClosed As Boolean)
Serial1.Disconnect
End Sub

to

Sub Activity_Pause (UserClosed As Boolean)
UserClosed = True
Serial1.Disconnect
End Sub

This did not help. Both versions disconnect the existing BT connection on exit, but neither switches off the bluetooth adapter in the device.

As you can see, I'm at the very early stages of the learning curve...

Thanks again,

Anand.

You can try this:

Sub Process_Globals
   Dim BTAdmin As BluetoothAdmin
End Sub

Sub Activity_Create(FirstTime As Boolean)
   If FirstTime Then
      BTAdmin.Initialize("BTAdmin")
   End If
End Sub

Sub Activity_Pause (UserClosed As Boolean)
   If UserClosed = True Then
      BTAdmin.Disable
   End If
End Sub

If you already have declared a BluetoothAdmin object in Process_Globals, you don't need to create a new one, you can use the one you have.

Galayxy Y has two buttons "Button 1" and "Button 2" that can ends the program.
If I press the "Button 1" The value of the variable UserClosed in the Activity_Pause is False.
If I press the "Button 2" the variable UserClosed is True.
How to disconnect the Bluetooth connection when user terminates the application by pressing "Button 1" ?

 

[Erel]

UserClosed in Activity_Pause will be true.

 

[pawel2420]

UserClosed in Activity_Pause will be true.

Only when I press "Button 2".
If I press the "Button 1" UserClosed is false

The Home button doesn't destroy the activity. You can always disconnect the bluetooth in Activity_Pause and start it in Activity_Resume. In that case it is recommended to lock the orientation of your app.

Thank you very much for your help.
Now I understand everything. Indeed, the Home button does not stop the application.

Indeed, the Home button does not stop the application.

True; but on my LG Optimus SOL, the back button as well as the home button disengages the bluetooth in my app, which is how I want it anyway.
