Have you tried to intercept the keypress with Activity_KeyPress sub?

Hello Erel

I try, in this way

Sub Activity_KeyPress (KeyCode As Int) As Boolean 'Return True to consume the event
   If KeyCode=KeyCodes.KEYCODE_HEADSETHOOK Then
      Label1.Color = Colors.Red
         
   End If

   
   Label1.Text = KeyCode
   
End Sub

KeyCodes.KEYCODE_HEADSETHOOK => works with handsfree cable:

KeyCodes.KEYCODE_HEADSETHOOK => No works with handsfree Bluetooth

Label1.Text = KeyCode => not generate code by pressing button Bluetooth Handsfree

Erel I thank you for the help you can give me

Try to intercept the following intent action: "android.intent.action.MEDIA_BUTTON"

Hello Erel

I did this, but it only works with handsfree cable

Manifest Editor

)
AddReceiverText(S1,<intent-filter android:priority="2147483647">
<action android:name="android.intent.action.MEDIA_BUTTON"/>
</intent-filter>
)

Service Module

Sub Service_Start(StartingIntent As Intent)
'
   If StartingIntent.Action = "android.intent.action.MEDIA_BUTTON" Then
      Log("se oprimio boton del manos libres")
   End If

End Sub

what I have researched, is that when you press the handsfree button it sends an AT command

AT+CKPD=200 =>Command issued by HS to indicate that the button has been pressed.

The problem is that it is the OS that handles this Bluetooth connection. So you cannot intercept the raw data.

 

[haesca29]

and if my program manages the Bluetooth connection, they might do something?

Your program can only manage SPP (serial communication protocol) connections.
