IR emitter and Android 5.0

I am facing a problem with the IR emitter on my Galaxy S5 running under Android 5.0.

Before I updated it to 5.0, my app was perfectly working on my phone but now, the device I am suppose to manage has no reaction. When I click on my app to send an IR code, the led blinks to indicate that the IR manager is activated and I can receive a signal with a IR photodiode connected to my scope. Unfortunately, the shape of the signal I get is very different from what it should be.

I can add that the same code running on my tablet under Android 4.4.2 still works perfectly.

To help in answering my question, a sample of my code :

private String commande="0000 0070 0000 0032 0080 003F 0010 0010 0010 0030 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 "
+ "0010 0010 0010 0010 0010 0010 0010 0010 0010 0030 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 "
+ "0030 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0030 0010 0030 0010 0030 0010 0030 0010 0030 "
+ "0010 0010 0010 0010 0010 0010 0010 0030 0010 0030 0010 0030 0010 0030 0010 0030 0010 0010 0010 0030 0010 0A98";

IRManager=(ConsumerIrManager)activité.getSystemService(Context.CONSUMER_IR_SERVICE);
code=commandConversion(commande);
IRManager.transmit(code.getFrequency(),code.getCodes());

private RemoteCommandeCode commandConversion(String command) {
    List<String> list;
    RemoteCommandeCode code;
    int frequency;

    list= new ArrayList<String>(Arrays.asList(command.split(" ")));

    list.remove(0); // dummy

    frequency = Integer.parseInt(liste.remove(0), 16); // frequency

    list.remove(0); // seq1

    list.remove(0); // seq2

    code=new RemoteCommandeCode(list.size());

    for (int i = 0; i < list.size(); i++) {
        code.setCode(i,Integer.parseInt(list.get(i), 16));
    }

    frequency = (int) (1000000 / (frequency * 0.241246));

    code.setFrequency(frequency);

    return(code);
}

public class RemoteCommandeCode {
    private int fréquence;
    private int [] codes;

    public RemoteCommandeCode(int nombreCodes){
        codes=new int[nombreCodes];
    }

    public int getFrequency() {
        return frequency;
    }

    public void setFrequency(int frequency) {
        this.frequency = frequency;
    }

    public int [] getCodes() {
        return codes;
    }

    public void setCodes(int [] codes) {
        this.codes = codes;
    }

    public void setCode(int i,int code){
        codes[i]=code;
    }
}

As asked, images of the signal emitted with the simple code "0000 0070 0000 0003 0010 0020 0010 0020 0010 0020", I get on 4.4.2 :

and on Android 5.0 :

This method will fix the IR problems for all Android versions

/*

*Edit: Thanks to the OP's help, I was able to figure out how to fix this. This answer should now solve this problem.
