tilt & led does not work with model 1517

[hrask]

I'm using Ubuntu 14.04 with Kinect 1517.

I finished build about freenect with reference to this page.
So I can do command freenect-glview in terminal. then I can see video and depth.
Several commands were displayed in terminal as follow:

'w' - tilt up, 's' - level, 'x' - tilt down, '0'-'6' - select LED mode, '+' & '-' - change IR intensity 
'f' - change video format, 'm' - mirror video, 'o' - rotate video with accelerometer 
'e' - auto exposure, 'b' - white balance, 'r' - raw color, 'n' - near mode (K4W only) 

But some command that tilt and led don't work .
I think that other settings are necessary when freenect building.
Next show terminal message.

I saw some solution to similar issues. but they are for Xbox kinect model 1473.
How can I solve for 1517 model?

For audio support, you must upload firmware to the device. Newer Kinect models may require audio firmware for motor and LED support. The best method is to insert firmware at runtime just after calling freenect_init().

Those files and code I linked will need to be added to any program where you want audio and/or tilt to work. Unfortunately the headers are C++, so you'll either have to compile the program as C++ or modify the headers to be pure C.

I know it's a PITA and I wish we could just ship the firmware, but the project doesn't want want to risk any legal issues.

Thank you for answering.
May be your advice is good.
But I don't know well about C, compile mechanism and so on.
If you are OK, could you tell me my mistake?

first, I got 2 files. and put in freenect/include/ .
next, I edited ofxKinectExtras.h like:

#pragma once
#define OFX_KINECT_EXTRA_FM

extern unsigned char fwk4wBin[];
int getFWSizek4w(){
     return 145920;
}
unsigned char * getFWDatak4w(){
     return &fwk4wBin[0];
}

and remove ofxKinectExtras.cpp after move "unsigned char fwk4wBin[]" of ofxKinectExtras.cpp to libfreenect/examples/glview.c code.

I edited
libfreenect/examples/glview.c row 494

if (freenect_init(&f_ctx, NULL) < 0) {
        printf("freenect_init() failed\n");
        return 1;freenect_init
    }

to

if (freenect_init(&f_ctx, NULL) < 0) {
        printf("freenect_init() failed\n");
        return 1;freenect_init
    }
freenect_set_fw_address_k4w(kinectContext, getFWDatak4w(),getFWSizek4w());

I retried to build. but the result did not change.

I would like to apply this solution to python wrapper, but what should I do it?
thanks.

There is a way to load firmware from a file; I know it works with model 1473, but I never tried it with 1517. To test it, you'd need to write that byte array you have in source code to a binary file named audios.bin and put it somewhere the loader knows to look, like ${HOME}/.libfreenect/.

The model 1517(for windows) seems to be different from model 1473.
so I can't solve.
Thank you for responding.
