Bluetooth library working in Processing?
Sep 8^th, 2007, 7:44pm

Hello,

I've read that the Bluetooth library ( http://mjs.darkgreenmedia.com/site/?service=Sections&task=showSection&sectionID=3&contentID=29 )
is supposed to work in both Mobile Processing and Processing. I need to detect mobile devices around a MacBook. Nonetheless, after following the installing instructions and trying to run the examples, Processing fires a compiler error and directs me to the bug section. I suspect that it might be a problem with intel macs, but want to be sure if anyone has experience with this before going to buy a bluetooth adapter for PC. Anyone?

Thanks

Avetana Bluetooth implementacion para Linux incluida (GPL) or Puede utilizar la version de Avetana Bluetooth licenciada para Windows, Linux y MacOSX or Otras implementaciones and Libreria Cliente Servidor (MClientServer)

I downloaded Avetana Bluetooth implementation placed it on the Library folder and changed the export.txt file (that's in the instructions for windows: http://processing.org/discourse/yabb_beta/YaBB.cgi?board=Electronics;action=display;num=1159140092
The other Library is installed but it wouldn't help. I run avetanaBluetooth.jar from the terminal and I don't get it quite right but it cannot detect my cellphone??? Actually he warns that the library has only been tested under Linux! so I guess it is indeed an issue of the library in Intel Mac/Mac OS X...Any help regarding mobile detection from a laptop/desktop or a similar library, or anything related is highly welcome!

Else I'll have to install Ubuntu in my macbook to try this! Would that work?

Ooops, without understanding really how, it looks like the Aventana demo responded, and now there's no more compiler error. Anyway there's an exception that I've found in this part of the forum (also related):

http://processing.org/discourse/yabb_beta/YaBB.cgi?board=os_libraries_tools;action=display;num=1154321908

It's a null pointer exception:

java.lang.NullPointerException
at mjs.processing.mobile.mbluetooth.MBluetooth.deviceName(Unknown Source)

I still hope to get help or an alternative. Fingers are crossed!

Hi,

I'm getting the same error on a Macbook Pro (Intel) OS 10.4.

And while trying out the pTictactoe example I get another error and wonder if they are related setting up paths:

Highlighted when sketch is run:

//// initialize Bluetooth library
bt = new MBluetoothP(this);

And the console reads:

java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/sun/kvem/jsr082/bluetooth/DiscoveryAgentImpl

Thanks for any help!

Some months after and I come back to this project. Somehow the Library seems to be useless in either intel macs or new processing versions. I tried it in Linux and is still giving me the same message. Has anyone achieved to work with Bluetooth communication in processing? Basic detection/communication? I cannot find many examples...and I'm not really versed in java matters as to try to implement my own library over the JSR-82...

hope someone has worked around this...Thanks

I recently ported Mobile Processing's Bluetooth library to Proce55ing, because I needed it for a project.

Be warned, it's a quick'n'dirty port Wink

but works. You'll need a jsr-82 implementation.
I'll pack it up as a library including documentation shortly. Untill then, try this and let me know if it works for you:
~~http://www.extrapixel.ch/processing/bluetooth_alpha.zip~~
UPDATE: download bluetoothDesktop here:
http://www.extrapixel.ch/processing/bluetoothDesktop/

Usage is exactly as described here, only the name of the callback method has changed:
http://mobile.processing.org/reference/libraries/bluetooth/index.php
including the improvements made here:

Hi! Thanks a lot for the post...I think it will do but since I was playing some time before with the free avetana implementation for mac, now the license is gone and that's the message I get in processing, so I should buy it...or use the free linux version(I have an intel mac with ubuntu7.04 as second OS), but I've wasted half of my day trying to compile that stuff, and I'm just an ubuntu newbie. Do you happen to have one recent compiled version? Or, did you buy it? Just to check, before giving those euros away:)

thanks again

Hi,

There's a compiled avetanaBT.jar in the download of the MBluetooth library for Mobile Processing. You can grab it from there:
http://mjs.darkgreenmedia.com/site/?service=Sections&task=showSection&sectionID=3&contentID=29

I couldn't test it though, as I don't have a linux box.

You can now download my compiled bluetoothDesktop library:
http://processing.org/discourse/yabb_beta/YaBB.cgi?board=LibraryProblems;action=display;num=1195091003;start=0#0

And if you use it and it works with the free avetanaBT & Linux, please report it in the bluetoothDesktop thread.
