Android 4.4 ConsumerIr.transmit goes crazy

Question

I am trying to write a little Android app that makes use of the new infrared API added in Android 4.4 KitKat. →Documentation

I run into trouble because my app freezes and gets killed because it is unresponsive.

Some code:

...
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    irService = (ConsumerIrManager) getSystemService(CONSUMER_IR_SERVICE);
    Log.d("transmit", "lets go");
    irService.transmit(38000, new int[] { 70 });
    Log.d("transmit", "done");
...

And the logcat of this:

01-24 01:28:25.450: D/transmit(10551): lets go
01-24 01:29:14.610: D/transmit(10551): done

The call to transmit takes more than 30 secounds!

From the Documentation:

public void transmit (int carrierFrequency, int[] pattern)
Added in API level 19

Tansmit and infrared pattern

This method is synchronous; when it returns the pattern has been transmitted. Only patterns shorter than 2 seconds will be transmitted.

Parameters
carrierFrequency    The IR carrier frequency in Hertz.
pattern     The alternating on/off pattern in microseconds to transmit. <---- this is wrong, see http://stackoverflow.com/questions/20244337

Throug my phones' camera I saw the IR-LED flashing all the time, so I measured the real transmitted times with an ir sensor (+ means burst, - means space):

Whats going on?

My device is a Galaxy Note 10.1 N8010 running OnmiROM 4.4 android. Maybe someone with a compatible device can test this?

Answer 1

Okay, after an update of OmniROM builds for my device the issue is fixed.
