Android Question How to enable bluetooth tether

[Kristofferson]

Using B4A, how do you turn on Bluetooth Tethering and allow the host device to share it's internet connection to the connected device? Also how to check the BT tether status.

I don't think that it is possible to programmatically start Bluetooth tethering.

The second link is not relevant. It is equivalent to BluetoothAdmin.Enable / Disable.

The code in the first link is based on private APIs. You can use the Reflection library to port it.

i already tryed but since i am 0% java programmer and 5% b4a programmer i don't know what packages to import .all i done was to put that in a class like here

Here:

Sub Process_Globals
   'These global variables will be declared once when the application starts.
   'These variables can be accessed from all modules.

End Sub

Sub Globals
   'These global variables will be redeclared each time the activity is created.
   'These variables can only be accessed from this module.

End Sub

Sub Activity_Create(FirstTime As Boolean)
   Dim jo As JavaObject
   jo.InitializeContext
   jo.RunMethod("BTPan", Null)
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub
