Android Question Bluetooth headset sco problem

[brelto85]

Hi all,

I've a serious problem with bluetooth headset's management
In my app, i've added a functionality that if the user, long press HOME button (ASSIST intent), run my app and start the voice recognition
If the bluetooth headset is connected, the voice recognition sound is redirected into bluetooth device using the starBluetoothSco() method (AudioManager native library)

this works perfectly!

After which i added another intent (VOICE_COMMAND) that fired if starts a voice command with bluetooth headset (long press button of device)

In this case the method starBluetoothSco() doesn't work and the audio not heard in the headset

i've attached a test project that simulates the behaviour
can you help me?
This failure prevents the publication of my app on the store

Where is the problem? Is the code executed and the Bluetooth doesn't connect?

Have you checked the unfiltered logs for any relevant messages?

this is the problem..

In this case the method starBluetoothSco() doesn't work and the audio not heard in the headset

the bluetooth is already connected, but after long press of bluetooth headset, start my app (with intent VOICE_COMMAND) and doesn't work method starBluetoothSco()
the unfiltered logs doesn't work after the updated at windows 8.1 (deploy through B4A bridge)
probably problem with driver usb

Is this code executed?

Sub StartBluetoothSco()
   Dim r As Reflector
   ToastMessageShow("Start sco", False)
   
   r.Target = r.GetContext
  r.Target = r.RunMethod2("getSystemService", "audio", "java.lang.String")
  r.RunMethod("startBluetoothSco")  
  Log("StartBluetoothSco") '<--------------
End Sub

yes

after other test i solved it putting a custom wait method after long press
probably the cause is that after long click the BT button, is not ready to start the sco

would be appropriate to intercept an intent that indicates the time at which it is possible to start the sco

Hi Brelto85,

Would you be good enough to share the code you have that is now working please? I'm trying to do the same thing with a BT Headset....

Many thanks
