I can't compare to any previous versions of OS X, but I've tried everything I can think of and I can't seem to get BTHSControl to respond to bluetooth evens from my headphones (e.g. Play/Pause still starts iTunes). I've also tried rebooting between service installations to no avail.

Here's a sample of what my syslog output looks like:

Hello James,
for some reason BTHSControl is not working for me. I stupidly forgot to disconnect all bluetooth devices before installing. that might be the reason.
My first attempt would be to uninstall and try again, but i cannot figure out how to remove it.

Would be happy if you can help me out. It seems to be a great application.

I have tried several times to get this to run now that I've upgraded to 10.11 and simply cannot get it to work. I have run these commands repeatedly just in case there something left behind somewhere:

sudo ./install.sh uninstall old
sudo ./install.sh uninstall
sudo rm -r build
sudo ./install.sh install

After I connect my BT headphones and try pressing the play/pause button I get the following in my system log:

10/19/15 11:11:54.010 AM com.apple.xpc.launchd[1]: (com.bths.AVRCPAgent[91875]) Service exited due to signal: Abort trap: 6

I am at my wits end on getting this to work again. Attached you will find the log mentioned above. You can find the above-mentioned crash report in this gist.

Thanks for this project, and great reverse engineering work!

One improvement: currently the simulated keyboard events are not sent if the display goes to sleep. In fact, it doesn't even wake the computer like it does when the keyboard is normally pressed during sleep. I'm not 100% sure why this is, but it seems like IOHID has some logic about consuming keypresses if display is sleep. There are also other reports of IOHIDPostEvent not working in sleep.

The fix is simple, use CGEventPost, which also ends up making the code a lot shorter

// Simulate the input of a keystroke based on an associated keycode
static void HIDPostAuxKey(int key) {
    // create and send down key event
    NSEvent* key_event = [NSEvent otherEventWithType:NSSystemDefined location:CGPointZero modifierFlags:0xa00 timestamp:0 windowNumber:0 context:0 subtype:8 data1:((key << 16) | (0xa << 8)) data2:-1];
    CGEventPost(0, key_event.CGEvent);
    
    // create and send up key event
    key_event = [NSEvent otherEventWithType:NSSystemDefined location:CGPointZero modifierFlags:0xb00 timestamp:0 windowNumber:0 context:0 subtype:8 data1:((key << 16) | (0xb << 8)) data2:-1];
    CGEventPost(0, key_event.CGEvent);
}

With this, things work as expected.

It appears that BTHSControl no longer functions with macOS Sierra, as tested with the GM released on September 8th.

I'm not fully sure if this is possible, but if we could get a pre-compiled version to download on top of the sources that would greatly help.

I now have to download 5gb of Xcode in order to run the install script. Depending on your bandwidth this can means a lot of time.

Hey, I was very interested in your project as I own a bluetooth headset with auto play and pause (based on when u remove your headset). This means that iTunes keeps popping up every so often which is a huge pain. I was looking at solutions to this problem and I came across your app. However, it doesnt seem to work on my 2015 Macbook Pro 13' running El Capitan. I don't mind disabling SIP in order to get this working either.

Where can I make a donation?

See clementine-player/Clementine#3262

Hi, not really an issue, more of a feature request/question!

I'd like to remap one of my buttons to be a mic mute. I have a bit of applescript to set the mic volume to 0 or 100 depending on whether it is already 100 or 0. But could I attach that to the button press code?
I'm guessing that the "if (status == 68)" bit in BTHSControlPlugin.m then calls
HIDPostAuxKey(NX_KEYTYPE_PLAY); in BTHSInterface.m
Can I easily make that jump out to an AppleScript instead or do I need to learn some cocoa ?

Thanks,
Max

Hello,

I installed your tool on my 2013 Mac running OsX Yosemite. I am using the Creative Aurvana Platinum-Headset and the Play, forward, backward buttons are working very well when I'm using the Clementine audio player.

However I have sometimes issues connecting my bluetooth headphones after the mac wakes up from the suspend. It seems to be a common Yosemite problem, and the solution I found lies in turning-off the WiFi and restarting the bluetooth services. Sadly, the BTHSControll is not working after suspend/sleep for me.

If I connect my BT headphones after a start after a power-off an message appears: AVRCPAgent: BTHSControll Bluetooth headset connected This message can be found in the OsX Messages - menu in the top right corner. This message does not appear, when I connect my bluetooth headset after suspend/sleep or after I restart the bluetooth services.

I wonder if there is a way how to restart the BTHSControll manually.
