Problem with Mac 10.8 and Bluetooth

[jmeyer2k]

Hi, I'm having problems getting bluetooth to pair between my Mac 10.8 and LeJOS. Whenever I try to connect, my NXT says UNSUCCESSFUL. If I try to pair from my computer, it flashes a code and then says pair unsuccessful. If I try running the program without pairing, or run nxjbrowse, this error comes up:

Code: Select all

dyld: lazy symbol binding failed: Symbol not found: _IOBluetoothLocalDeviceReadSupportedFeatures

uploading the program failed with exit status 133


I have done a little bit of research on the pairing problem and it is an authentication failure. Please help!!!

We are aware of the problem. Unfortunately, there is no easy fix right now. The library we use for Bluetooth (bluecove) is simply broken on 10.8, as Apple decided to finally remove functions that they had deprecated since a few OS X version.

Hi,

I'm having the same problem.

Has there been any progress in resolving this issue?

Hello,
I had the same problem after updating to OSX 10.8.
Since I wanted to connect to my NXT via bluetooth again, I spent some time with Objective C, IOBlootooth.framework and maven2. My objective was not to fix or update bluecove, but to be able to use leJOS with bluetooth again. I did some ugly things like returnig services of the host adapter without truly requesting (I did not find a suitable method in IOBluetooth now) or commenting out deprecated code I did not understand.
As a result of my effort I built this patch for the svn-version of bluecove. The resulting "jar" worked for my NXT at least for uploading and for data logging but I am sure, that some functionality of bluecove will be lost or will lead to unstable behaviour.

You can download my patch here:
https://docs.google.com/file/d/0B-GAbqyW_Z6UY0JNU2puRE95QTA/edit?usp=sharing

get bluecove with

Code: Select all

svn checkout http://bluecove.googlecode.com/svn/trunk bluecove-parent

copy bluecove.patch to ./bluecove-parent

Code: Select all

cp bluecove.patch ./bluecove-parent

and cd to ./bluecove-parent

Code: Select all

cd bluecove-parent

apply the patch with

Code: Select all

patch -p1 < bluecove.patch

and start the build process with

Code: Select all

mvn -Dmaven.test.skip=true

Not all the targeds will be built successfully but you will find what you need in the subfolder

Code: Select all

./bluecove/target

You can then make bluecove-2.1.1-SNAPSHOT.jar available for your leJOS build system.

I hope, that this patch will help some of you in order to use leJOS with bluetooth support again on OSX 10.8.

Kind regards
Wulf

Hi.

I tried this with no success. After your process, I just replaced the bluecove.jar (in my snapshot) with the one generated. Would you like the exception dump?
