Send a 64bit Infrared signal with android

Question

Using a raspberry pi 3 and an infrared reciver. with the help of a library called LIRC I recorded the signal of my android box remote control.

begin remote

    name  MyRemote
    driver devinput
    bits           64
    eps            30
    aeps          100

    one             0     0
    zero            0     0
    pre_data_bits   64
    pre_data       0x0
    gap          509
    toggle_bit_mask 0x0
    frequency    38000

    begin codes

        KEY_ENTER                0x1167000001000268
    end codes

end remote

The problem is I can not find a library that can help me write code to send the IR signal from my Note3.

Answer 1

I tested ConsumerIrManager on Redmi Note 4, probably it will work on Note3 too.

Add permission to the manifest:

<uses-permission android:name="android.permission.TRANSMIT_IR" />

And in code:

1. Retrieve ConsumerIrManager

val irService = getSystemService(Context.CONSUMER_IR_SERVICE) as ConsumerIrManager

2. Check if emitter exists

irService.hasIrEmitter()

3. Check if target frequency is supported by emitter

fun isSupportedFrequency(irService: ConsumerIrManager, targetFreq: Int): Boolean {
        irService.carrierFrequencies.forEach {
            if (it.minFrequency <= targetFreq && targetFreq <= it.maxFrequency) {
                return true
            }
        }
        return false
}

4. Transmit data

irService.transmit(targetFreq, data)

UPD1:

To send 64 bit keys maybe you can split them into two 32 bit keys.

UPD2:

Under the hood ConsumerIrManager uses ConsumerIrService, which uses native method private static native int halTransmit(int carrierFrequency, int[] pattern);, which supports only 32 bit pattern slices. So probably there is no hacky way to send 64 bit slices, if splitting won't help.
