I see the same problem when loading a Bluetooth related OSGi bundle in the 
OpenHAB project. This bundle is using bluecove-2.1.1-SNAPSHOT.61, running on OS 
X 10.8.2. Java JDK information:
    $ java -version
    java version "1.6.0_35"
    Java(TM) SE Runtime Environment (build 1.6.0_35-b10-428-11M3811)
    Java HotSpot(TM) 64-Bit Server VM (build 20.10-b01-428, mixed mode) 

The error I see in the log output is:
dyld: lazy symbol binding failed: Symbol not found: 
_IOBluetoothLocalDeviceReadSupportedFeatures

Maybe Java is trying to call a function through JNI that does not exist in the 
shared lib?

Seems like IOBluetoothLocalDeviceReadSupportedFeatures has been removed by 
Apple.https://developer.apple.com/library/mac/#releasenotes/General/APIDiffsMacO
SX10_8/IOBluetooth.html However I have no idea about how to fix it. 
Unfortunately.

Original comment by moller2...@gmail.com on 11 Oct 2012 at 3:48

[GoogleCodeExporter]

Is it possible that IOBluetoothLocalDeviceReadSupportedFeatures has been 
replaced   kBluetoothHCICommandLEReadLocalSupportedFeatures? 

Clearly, the old call is not coming back. To un-break this, Apple's new call(s) 
need to be added to BlueCove.

Note that a temporary workaround has been found:

 * http://www.uweschmidt.org/wiimote-whiteboard/comment-page-45#comment-246167

As it involves copying a system file (IOBluetooth) from a previous version of 
OS X and using DYLD_LIBRARY_PATH  it is not a permanent end user solution for 
both technical and legal reasons.

jepp, that worked for me. download the IOBluetooth file from uwe and change the 
startup script in order to start eclipse like this:

I just created a new version of the OS X stack that utilizes Grand Central 
Dispatch for asynchronous tasks and supports the latest 10.8 Bluetooth-Stack. 
How could we stabilize and incorporate this into bluecove. I ask in particular 
for intensive testing of all the different functions that i could not verify in 
my environment.

In addition, this version most likely will not work with older versions of OS 
X, so maybe it could be easier to split the two into a pre 10.8 and 10.8+ 
binary that are loaded depending on the runtime environment.

@die.paulinis: I would be very interested in these patches because I have an 
application that I can't get to run on OS X 10.8. Do you have the patches 
uploaded somewhere or is there a precompiled version with your changes that I 
can get access to?

As for the integration with bluecove I think it would be a good idea to create 
a new binary for 10.8+ and leave the old binary alone. This way you can easily 
make sure that no existing (10.7) functionality will become broken.

Sorry but i did not receive any mails for your comments and was kind of

I will figure out some easy way to share the code with you. Most likely i will 
push the code to github tomorrow. I will share the location with you ASAP.

[GoogleCodeExporter]

@all: You can find the forked repository at github: 
https://github.com/ma-ku/bluecove. Actually i did not change the java code and 
only worked on the native library. All the changes are made in 
OSXStackRFCOMM.mm, mainly i changed everything to utilize GCD and semaphores. 

I am able to use the library with LeJOS to program and control my NXT brick. 
Unfortunately the transmission to the brick is rather slow since only a few 
bytes are sent on each call. If anyone of you knows a way to speed this up, i 
would appreciate contributions to the code.

Have fun...

I used a workaround to fix this issue for blucat. I modify the 
DYLD_LIBRARY_PATH variable to contain an older IOBluetooth library that works. 
For this I don't need to change any jar files. You just modify this variable on 
new max versions.

Well, i have seen these approaches. Nevertheless i personally prefer a solution 
that does not rely on exchanging system libraries. As i already wrote, the 
library is working except for the performance issue with the RFCOMM Channel and 
i would appreciate a solution to that issue, going with the original system 
libraries of OS X 10.8.x.

Has this been resolved?  i.e. Has Bluecove released a new version that works on 
OSX 10.8?

Original comment by cagiva...@gmail.com on 10 Jun 2013 at 6:11

[GoogleCodeExporter]

@ cagiva851: I did a personal build of the required .dylib using XCode and used 
this file to replace the original version in the bluecove.jar. Anyway, the code 
was released on github so you should be able to do your own build. I personally 
have not spend any effort on how to run a complete build of bluecove so maybe 
anyone can assist?

Hi guys,

Have anyone found or documented a working solution, which is replicated by 
other people? I tried all suggestions and none works for me. :(     Any 
guidance would be very much appreciated!

1. I have MAC and I do not believe that there is hcitool equivalent on Mac.

2. A solution from Uwe: Changing the DYLD_LIBRARY_PATH environment variable to 
point to the old IOBluetooth library gives this error:

You can check out the code from https://github.com/ma-ku/bluecove and compile 
it on your machine. Then add the resulting library to your java.library.path.

I've attached the bluecove jar that I use on my machine (compiled some weeks 
ago). Maybe it will work for you too.

I upgraded to OSX 10.9 before I tried the attached file and it didn't work. 
However I compiled https://github.com/ma-ku/bluecove on my machine and it seems 
to work. Actually, it doesn't give any error, it correctly shows unknown / 
unpaired devices, but it always shows zero paired devices, when Mac sees 
several paired devices. Don't know where to go from here :(

Original comment by de...@google.com on 10 Dec 2013 at 8:20

How do you look up the paired devices? Looking up paired devices should be 
supported (the changes where merged into the codebase at 
https://github.com/ma-ku/bluecove). I also use OSX 10.9 and it seems to workf 
for me. Can you provide your java code?

I think that my problem was related to the GUI implementation. I used the 
standard SWT that for some reasons is 32bit, so I was running my app 32bit. I 
now included a 64bit SWT library and I am running my app at 64bit, and it seems 
to work.

Still I don't know why I can't build the library though...

Hi,

I'm trying to get LEJOS to work on OS X. So far I've been through the following 
steps:

1. Clone https://github.com/ma-ku/bluecove
2. Open the bluecove XCode project, set target to 32-bit, and compile the 
library (had to remove a few includes which weren't used).
3. Installed ant to compile the bluecove jar file (with success). I replaced 
the bluecove.jar in LEJOS with the one I just compiled, which fixed some errors.

So now I only have to get it working with Eclipse.

#30: I found out that running the LEJOS tools directly (without Eclipse) on a 
32-bit JVM 6 gives the same error. From the source of the LEJOS tools I found 
out that it automatically sets -d32 on OS X, so this doesn't seem to be the 
cause of the error.

I just tried doing it all over and now I get the error (I realized that I had 
some old bluecove jars in the classpath, so changes to the new one never had 
any effect since it was loaded later):

How I did the following:

1. Clone https://github.com/ma-ku/bluecove
2. Open the bluecove XCode project, set target to 32-bit, and compile the 
library (had to remove a few includes which weren't used). This produces 
libbluecove.jnilib
3. I then ran ant in the "bluecove" directory which produces two directories: 
com and javax, which contain various class files.
4. I zipped the com, javax and libbluecove.jnilib and renamed the file to 
"bluecove.jar" and replaced it with the one which ships with LEJOS.

When running one of the LEJOS tools which connects via USB, I get the following 
error:

It seems that I'm getting closer, but I don't know how to proceed from here. 
Any help is greatly appreciated :-)

Building the ma-ku fork from github I hit an issue where javah was not 
generating headers so I had missing files for some native includes

#include "com_intel_bluetooth_NativeTestInterfaces.h"

The issue turned out to be the javah task I had for maven 2 is expecting a 
different syntax

In bluecove/bluecove/pom.xml

<configuration>
    <outputDirectory>${native.source.dir}</outputDirectory>     
    <classNames>...

Had to be changed to this - seems the config property names have changed.

<configuration>
    <javahOutputDirectory>${native.source.dir}</javahOutputDirectory>     
    <javahClassNames>

I've built the library successfully from ma-ku fork, but I get an hard crash 
(log attached).
All tests during build are successful.
The only difference I see is that I'm using a recent VM, instead of the 1.6
Did anyone share the same problem or a clue?

Since development appears to have stopped back in 2011, I suspect you're on 
your own.

I found for 10.9 many things break.  I found the jarias bluecove update 
(https://github.com/jarias/bluecove) is best and allows RFCOMM sockets but 
scanning is broken and I think many other things. 

I attributed it not working in 10.9 to Apple changing their interface. I was 
running bluecove on 10.7 and 10.8 by just setting DYLD_LIBRARY_PATH to point to 
an old IOBluetooth object from 10.6. But this doesn't work anymore so I think 
Apple changed things.

I use this library for my project which need to connect LEGO Mindstorms NXT via 
bluetooth, and had problems on Max OS X Yosemite Beta 2.

I've rebuild the bluecove library with some fixes form the jarias update 
(https://github.com/jarias/bluecove), and it works for me. I believe this can 
work both on Mavericks and Yosemite Beta 2.

Hi Kris,
your version works much better but I'm still having issues while reconnecting. 
Can you share your fixes to the jarias update?

Hi, are the problems on Yosemite sorted out by now? If so, can someone please 
compile a version that will run on 10.8 up to the latest 10.10.X?

Thanks,
Uwe

Hello all... I am the developer of www.aioremote.net mobile remote app and was 
searching a lot for a fix for bluetoth on mac and finally found the fix here. 
Thank you very much

I tested  bluecove-2.1.1.jar  provided by Kris and it worked on my Mac 10.10 
Yosemite

I will do more tests before updating my desktop app but I wanted to let you 
know the result of my initial tests

I have had success on Mac OSX 10.9.5 using the bluecove version from: 

   https://github.com/machaval/bluecove

The issue with slow interaction with Lego NXT that was reported above can be 
fixed by making some
changes to the OSXStackRFCOMM.mm file (in bluecove/src/main/c/intelbth).  In a 
number of places the following is used:

   dispatch_time(DISPATCH_TIME_NOW, NSEC_PER_MSEC * 500));

Performance can be improved (at least in my case) by changing all of those 
lines to:

   dispatch_time(DISPATCH_TIME_NOW, 1));

The modified file is attached.  Just replace it in the source from the git 
above and run maven in the bluecove directory.

Or... I have also attached a the resulting Jar file that may work for you 
straight away.

Good luck!
