Bluecove programming problem

Hi,

I'm not able to get my java Bluetooth application up and running on my Raspberry Pi.
It runs well on my Windows PC
Bluetooth itself works fine on my Rasp when I check it with "hcitool scan"

I use the Bluecove library and when I start the jar on my Rasp I directly get an error stating: "Native Library bluecove_arm not available"

I scanned the internet and tried all tips and tricks I found.
The most helpful sites were:

https://sites.google.com/site/opengaragedoor1/home/stages/raspberry-pi
http://code.google.com/p/bluecove/source/browse/trunk/bluecove-gpl/build.sh?r=3045
http://www.raspberrypi.org/phpBB3/viewtopic.php?t=34841&p=294901

But none of them could solve my problem.

Can somebody who has a java Bluetooth application successful running on his Rasp tell me how he managed that?

On my Raspberry Pi I installed the latest image (2013-09-10-wheezy-raspbian.img) together with Java(TM) SE Runtime Environment (build 1.7.0_40-b43)

Many thanks,
MyRevel

Solved

Here a step by step description how I succeed to get the needed Raspberry bluecove-gpl-2.1.0.jar:

On my Windows PC:

Download bluecove-2.1.0.jar and bluecove-gpl-2.1.0-sources.tar.gz from:
http://code.google.com/p/bluecove/downloads/list

Prepare source:
    1) Unzip bluecove-gpl-2.1.0-sources.tar.gz
    2) go into folder bluecove-gpl-2.1.0 and open file build.xml in a text editor
    3) Delete text '-SNAPSHOT' in line 12:
    change: <property name="product_version" value="2.1.0-SNAPSHOT"/>
    into: <property name="product_version" value="2.1.0"/>
    4) save file

Open Raspberry Pi in program WinSCP and go into home folder (/home/pi)
Create new folder named temp
Go into temp folder (/home/pi/temp)
Copy complete folder bluecove-gpl-2.1.0 including modified build.xml file into folder temp
Add new folders bluecove/target into temp (/home/pi/temp/bluecove/target/)
Copy bluecove-2.1.0.jar into folder /home/pi/temp/bluecove/target/
(now folder temp includes two folders: bluecove-gpl-2.1.0 and bluecove)


Open Raspberry Pi in program Putty

Install Bluetooth:
    sudo apt-get update
    sudo apt-get upgrade
    sudo apt-get autoremove
    sudo apt-get install bluetooth bluez-utils blueman

Connect Blutooth dongle and test if Bluetooth OK:
    /etc/init.d/bluetooth status -> check to see whether the bluetooth is live
    hcitool scan -> show any devices in range of the dongle

Install the BlueZ devel package needed for compilation later:
    sudo apt-get install libbluetooth-dev

Install Apache Ant:
    sudo apt-get install ant

After all these updates I prefer to reboot:
    sudo reboot

Go into folder bluecove-gpl-2.1.0:
    cd /home/pi/temp/bluecove-gpl-2.1.0

Start compilation:
    ant all

When successful compiled you can find the required gpl jar in:
    /home/pi/temp/bluecove-gpl-2.1.0/target/bluecove-gpl-2.1.0.jar
Add the file bluecove-gpl-2.1.0.jar together with bluecove-2.1.0.jar into
your java build path libraries of your java development program.

Blimey. Bluecove. That takes me back. From AUTHORS.txt:

Hello everyone:

First of all thank MyRevel for creating this useful guide. I would like to say that I have had trouble getting to recognize my bluetooth dongle and Raspberry Pi. I've solved by running the command:

Code: Select all
depmod-a


after the command
Code: Select all
sudo apt-get install blueman bluetooth bluez-utils


Moreover, all great

thanks :D

Hi abbas-h

What I understand from your question is that you are running your java program on a Windows PC and you get that error message.
I can reproduce simulair error when I run a program and the bluetooth dongle is not well installed on my Windows XP PC.

So my question: is your dongle correctly installed and can you setup connections from other devices like mobile phone to your PC?
If not, please check your bluetooth dongle installation.

This process above did not work.
I got below errors from Maven:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.2:compile (default-compile) on project obd-java-api: Compilation failure: Compilation failure:
[ERROR] /home/pi/vg/raceiq-obdii-api/src/main/java/com/TestHarness/RemoteDeviceDiscovery.java:[17,1] package javax.bluetooth does not exist
[ERROR] /home/pi/vg/raceiq-obdii-api/src/main/java/com/TestHarness/ServicesSearch.java:[18,1] package javax.bluetooth does not exist

Any clues? it has been a nightmare to develop Bluetooth project on raspi.
