Bluetooth discoverable status on application start

Question

How can we have the bluetooth discoverable status on application start

I have an Image view for showing the status but its not showing the appropriate Image on start of applicaton

In oncreate() I have the following code

 mBtAdapter = BluetoothAdapter.getDefaultAdapter();


    if(mBtAdapter.isDiscovering()){
        bt_strength.setImageResource(R.drawable.bt);

    }
    else if (!mBtAdapter.isDiscovering()){
        bt_strength.setImageResource(R.drawable.bt_grey);
    }

Even this code also not working

      mBtAdapter = BluetoothAdapter.getDefaultAdapter();

     int status = mBtAdapter.getState();
    if(status == mBtAdapter.SCAN_MODE_CONNECTABLE_DISCOVERABLE){
        bt_strength.setImageResource(R.drawable.bt);

    }
    else if (status == mBtAdapter.SCAN_MODE_NONE){
        bt_strength.setImageResource(R.drawable.bt_grey);
    }

How I can get around this problem? Any help is appreciated

use below code

   mBtAdapter = BluetoothAdapter.getDefaultAdapter();


    if(mBtAdapter.getScanMode() == BluetoothAdapter.SCAN_MODE_CONNECTABLE_DISCOVERABLE)
    {
        bt_strength.setImageResource(R.drawable.bt);

    }
    else 
    {
        bt_strength.setImageResource(R.drawable.bt_grey);
    }

Thanks for the reply, I tried with ur code also but its not working – Randroid Jun 18 '12 at 06:04
I think you are tried mBtAdapter.getState() not mBtAdapter.getScanMode(). – Vivek Kumar Srivastava Jun 18 '12 at 06:05
Thanks a lot ,its working. so if the status is on/off its showing the correct image.I have one more question, On clicking that Image view can we stop the discoverable condition before timeout – Randroid Jun 18 '12 at 06:20
yes you can, but you need to disable the bluetooth to stop the discoverable by using mBtAdapter.disable() – Vivek Kumar Srivastava Jun 18 '12 at 06:28
APi have one more method cancelDiscovery(), you can try this – Vivek Kumar Srivastava Jun 18 '12 at 06:29
