J2ME - scan for bluetooth devices

Hello,
Where can i find an example of how to get (in the console, for example) the active bluetooth devices? I need a java program regarding to this. I know there are some examples, but where can i find a good example in this sense? Can you give me some examples?
The idea is that i wanna store in a file (local file) all the active devices.
I don't have a real bluetooth device, but using emulators.
Thanks!

Hi everybody, here you'll find a MIDlet code for bluetooth device descovering
hope it will be helpful

HT204368 iPhone continues to search for bluetooth devices even when connected thus affecting battery.

iPhone 4S continues to search for bluetooth devices even though it is connected to one.
Can this be stopped to save battery?

Why do you believe this is true? If you're looking at the bluetooth settings page, simply opening that page in settings initiates the search. It stops when you close it.
Like the light in your fridge.

Can I force LE 8 to scan for audio device?

I run all recordings through a Mac Min. As there is only 1 firewire port, I need to have my mixer feeding into a powered hub. When I start the Mac, it doesn't retain the connection to the mixer and I need to switch the mixer and the mic off on order to let Logic go through the scanning process to re-acquire it. This isn't really a problem, but I find it really irritating. When I had a direct firewire connection to the control room iMac, it always 'saw' the mixer and mic.
Can anybody suggest a way to keep the connection/setting or can I force Logic to do the scan for audio devices without having to turn the mixer off and on.
Thanks.

I am aware of the "hold alt key" at start up. However this doesn't work for me for some reason

Disable scanning for new devices?

Another new user question: Is there a way to disable the automatic scanning for new devices in Logic Pro 9? At the moment, my system is connected to a KVM (w/USB) switch, and every time I switch to the system running logic, it asks me if I want to use my USB headset, which is on the KVM switch, as an audio device (I don't). It would be nice if I could turn off that function and scan manually when I add a device that I want to use with Logic. Thanks...

Hi Stephan,
Not yet. This is a new feature we added in December to demonstrate during registration that the Service Request automation is working.
While these Demo Service Requests are real Service Requests, they are held in a special queue and not routed to TAC engineers. Smart Call Home will automatically close every Demo Service Request after a short time.
In the next release, we plan to implement a toggle in the Smart Call Home portal so that you can control this feature.
Feel free to continue registering devices. Demo SRs are just an additional validation that everything is working. They shouldn't create any additional work for you or for TAC.

Search For Bluetooth Devices

I dont know how to search for bluetooth devices on nokia e65. Need to set up a handsfree car kit with it. Where do i go on the phone to search for bluetooth devices??

Hi lindi9
Select Menu > Connect > Bluetooth.
1. When you activate Bluetooth for the first time, you are asked to give a name to your device. Give your device a unique name to make it easy to recognize if there are several Bluetooth devices in the vicinity.
2. Select Bluetooth > On.
3. Select My phone's visibility > Shown to all.
Happy to have helped forum in a small way with a Support Ratio = 37.0

Stop Logic Pro X from scanning for bluetooth

When Logic Pro X is open it scans for a Bluetooth Speaker that is connected to the iMac.
Is there a way to stop Logic from performing the scan when the Speaker is turned on?

Remember, 'Support' doesn't actually mean that this is a complete list of controllers that will work. It's simply a selection of presets containing pre-assigned MIDI controls, a bit like you telling an electronic drumkit to play C3 when you hit the kick etc.
Most controllers have a 'Mackie Control mode' that change the assignements in the controller to ones identical to the Mackie control and thus work with the Mackie Control preset. Nealy all the rest have presets online that can be added to the list and used.

Network manager no option for bluetooth devices

I am using network manager version 0.8.1-1
as stated in the wiki http://wiki.archlinux.org/index.php/Blu … GPRS_Howto
"Right click on nm-applet and choose "Edit Connections", choose Mobile Broadband tab, click "add" it will pop you up to choose a Mobile Broadband Connection, there you can see your bluetooth device. "
I followed this and I couldnt see any bluetooth device option in the pop up
In my previous version It was showing

Hello,
I'm having the same Problem with missing bluetooth modem/device when trying to add a new "Mobile Broadband" connection in NM.
Installed versions are
bluez 4.84-1
blueman 1.21-6
networkmanager 0.8.3-0.20101130
modemmanager 0.4-1
Im using Kernel 2.6.36-ARCH with KDE on my Lenovo Thinkpad X201. Mobile phone is Nokia E52 with installed Internetprofile.
Is somebody still on it?
Has someone an explaination/solution?
Best Wishes
P.S. with gnome-bluetooth doesn't work as well. It even does not serve any other services than OBEX for my Phone.
Edit: In fact gnome-bluetooth is the solution:
1) Do not use blueman-applet. Use bluetooth-applet instead (package gnome-bluetooth)
2) Re-pair Phone, enter PIN
3) Last step of the pairing wizard offers a checkbox to 'use this phone as modem'.
4) After enabling that checkbox another wizard appears to set up your mobile-internet-provider or connection details.
5) Finally the phone is listed in tray-menu of networkmanager. One click on it establishes the connection. (Disconnect works the same way)
Sadly I can't rename the connection in the tray-menu of networkmanager. This connection is not listed under "Mobile Broadband", only in tray-menu.

Must reboot for Bluetooth devices upon waking...

I have this chronic problem where I wake up the computer and there is no Bluetooth. Meaning no keyboard or mouse either. No amount of trying to restart Bluetooth or telling to to "connect" will help. The only solution is to reboot the computer. Upon rebooting, devices are connected as normally.
Is this a known problem? It seemed to start with the 10.6.3 update a month or so ago. It sure is annoying when it happens.
This is an Intel MacBook Pro with Magic Mouse and Apple BT keyboard.
HELP!

It seems like this is only a problem with the external display attached, or when the computer goes to sleep after pulling out the power plug. The Bluetooth devices don't seem to be disconnected when the computer is woke up while the display is not connected. Over the next several days I will look closer at the cause.

Volume for bluetooth devices not working

I have a pair of Bluetooth headphones and since updating to Yosemite 10.10.3, I have not been able to control the volume of them with the volume keys on the keyboard or the volume in the menu bar 99% of the time. I have once gotten it to work and have no idea what I did for it to work. If I take the volume all the way to 0, it does mute the audio and the mute key still works as well.
Changing the volume manually in individual apps (such as with the slider in Spotify or in a youtube video) works but thats only when I use the mouse to move the volume slider.
I've done some searching around and it seems like Yosemite has numerous Bluetooth issues... I even had the horrendous screeching noise in 10.10.2 but that seems to be fixed now.
Mid 2009 Macbook Pro 5,3

I cheated and installed Windows 7 RC. ^.^
But something you can do is:
Click on the Start menu
In the search bar look up 'Services'
Open up Services
Double click 'Bluetooth Services'
In the 'Log On' tab check to see if 'Local Service' or 'Use This Account' is highlighted
If 'Local Service' is selected then you're SOL and you're best bet is to re-install Windows. That's what was selected on mine and no matter what Account I set it to Bluetooth would not work. I even tried re-installing the Apple drivers from the OS X disc.
But if 'Use This Account' is selected than I would look into the normal Bluetooth settings, as the problem is most likely there. You can also call MS and have them screen share with you, the guy I talked to said if 'Use This Account' was selected he could do more for me.
Anyways hope this helped a bit.

HT204368 4S searching for Bluetooth devices but not finding them?

Hi I have just bought a second hand Iphone 4S from a company online and I am trying to get Bluetooth headset paired.
I have turned the Bluetooth off and on, and the headset - I have put the bluetooth function on my other work phone a Blackberry and the iPhone is not finding them - it just keeps searching?
Tried to pair from the Blackberry and it would not work either
Can anyone suggest anything?
thanks

Stop trying. The iPhone Bluetooth does not include the necessary protocols to pair with another phone. The headset on the other hand should be OK.

Scanning for a newly plugged in MIDI device

Hi all,
I'm currently using javax.sound.midi in my project and I have to implement a feature where the program detects if the user plugs in a new midi device during runtime.
This is a bit of a problem as mentioned here:
http://stackoverflow.com/questions/3752352/java-sound-api-scanning-for-midi-devices
Basically javax.sound caches the providers list for a minute, and I did what was suggested in the thread to set the caching period to 1 second. Unfortunately, this did not work for me (I'm running on Mac OSX). I can see that the providers list are new objects but it still doesn't detect the new plugged in device. However, it does work on the PC. So my question is, does anyone have any suggestions on how to getting this working on all platforms?
Any help would be greatly appreciated!
George

I have the new iphone 4S (this is my first iphone) I am having trouble connecting to my bluetooth device - the iphone is searching for the device but won't recognize it (my bluetooth device is a jawbone)

My iphone 4s does not recognize my bluetooth device - I don't know why
My bluetooth device is a jawbone and I have turned it on and sitting next to my iphone which is searching for bluetooth devices but will not recognize it
Not sure why

dugasgre wrote:
Thanks for the advice
I just tried turning the jawbone off and then turning it on and shaking it 4 times but the iphone 4s still won't recognize my jawbone
Do I need to unpair the jawbone from my blackberry first? And if so, how do I do that?
so after double shaking, is the ring flashing red +white? If it is not, then it is not in pairing mode. (I'm assuming you have the ERA) And you see nothing on the iphone? Nothing is found? Or is the device found, but not paired.
try placing the jawbone in pairing mode first, and then turn off/on the iphone blue tooth.
I don't think you need to unpair with the BB. But you can try. go to BB settings and there should be a way to forget the device.

TIP for Bluetooth, Vista 64-bit, and PalmZire72

I'm indebted to all the folks who have added so much to the discussion and hopeful solutions to the VISTA 64-bit problem for those of us who desperately want to keep using our dependable PALM devices. (Too bad that Palm as a company is not so dependable!)
I got a Palm Zire 72 back in 2004 and it has become a vital part of doing business and living life since that time.
I've always synced to Outlook2003 for my Calendar, Contacts, Tasks, & Notes.
When I bought a new laptop with VISTA 64-bit, I had forgotten my previous determination to NOT go with 64-bit. However, the price was too good on a last display model HP and I grabbed it, 64-bit VISTA notwithstanding.
Then I did research here on this forum and I knew I needed a bluetooth adapter that had at least SOME success with VISTA 64, but I didn't read far enough to steer me to the Iogear adapters that seem favored here.
I bought an off brand AZIO from NewEgg after reading of others having some success with this adapter.
I hope my observations can help others, either with these or other brands that may have the same problems.
I already had my MSOffice installed on the HP, and had backed up my full Personal Folders from the old Compaq and then pointed the new installation to a copy of the PST file, which brought over everything including emails to the new PC.
This was probably not the best way to go because I got myself into a pickle because I used the new PC for downloading emails, but I could not sync to this PC with my Palm
I also downloaded the latest PalmDesktop, version 6.2 by Access and installed it to the PC, telling it that I wanted to sync to Outlook for my Calendar, Contacts, Tasks, Memos, and some other things I'm unsure of now.
Anyway, once I got the AZIO adapter, I installed it to the PC and tried to address the various issues before trying to sync.
I made sure the name on my PalmZire72 matched the name PalmDesktop used for me.
I checked my Device Manager and it listed my Bluetooth Device (with about 5 line items showing as various Toshiba Bluetooth devices, since the AZIO uses the Toshiba Bluetooth stack for its drivers. There was also a bluetooth radio listed there.)
I tried to setup my devices with the Palm device, turning on Bluetooth, making it discoverable, but I got no Bluetooth option listed when I looked at the possible HotSync methods. I could only choose USB or Network or Serial, but no Bluetooth option.
I selected Serial and tried to use a Port that I could see in Device Manager on the PC under Ports. I tried using all the ports showing as connected to the Toshiba device but none of them allowed a HotSync to work.
I created a port using the Bluetooth Local COM program listed at the bottom of my programs within the Control Panel on the PC. I pointed the Palm Serial Sync to that port but still no luck.
The weird thing was that I KNEW my PC and PALM were talking because they each would discover the other and know the correct name I had given the other device. I knew the Bluetooth device was connecting somehow, but every time I ran the Setup Devices on the PALM bluetooth setup, it would end with the "port being used by other application" message.
I ALSO noted that even though Device Manager knew I had the bluetooth device installed, I NEVER found any such devices listed in the Bluetooth Devices program that I could pull up from either the tray icon or from Control Panel. It would always be empty and I couldn't get it to discover any device on my computer.
I tried various uninstall/reinstalls of both the PalmDesktop and the USB Bluetooth adapter, but nothing changed anything. Each time I could verify that the Palm and the PC would identify the other one by correct name I would assign, but I could never get a device listed in the critical Bluetooth Devices program and HotSync would fail.
FINALLY, after giving up and buying a new Iogear GBU421 WM adapter tonight when I found one at WalMart, I came home and began the battle again.
But I couldn't quite give up on this AZIO without ONE more try at it. I had read about installing Generic drivers in place of the ones given with a device, and I don't even think these were in the same setup as mine, but I wanted to give it a shot. These were on the "Vista 64 Hotsync solution found" thread that has so much info on it. I posted a new thread simply because I hope this specific piece to the puzzle may be found a bit quicker in its own thread.
I went to Device Manager, looked at the various drivers, wondered which one to change first, and decided to change the Bluetooth radio driver first. I don't know why. Lucky guess? :-)
It seems to me it may not have had a Toshiba designation as did the other various ones listed there.
Then I also changed the Toshiba RFCOMM listed, and pointed it to something different. It was guesswork at best, but I was searching for generic drivers.
After this, the other Toshiba Bluetooth devices mostly disappeared from the Device Manager list of Bluetooth devices. It now also divided them into TWO categories, Bluetooth and Bluetooth Radios.
Bluetooth only shows a Bluetooth RFCOMM.
Bluetooth Radios shows a Generic Bluetooth Radio and a Microsoft Bluetooth Enumerator.
None of these shows a red X or other problem mark.
In my Systray, however, I show a normal blue/white icon for Bluetooth Devices and a blue/red icon for Bluetooth Manager.
The Devices window will show my Palm Zire listed with my assigned name.
The Bluetooth Manager window, identified as Bluetooth Settings, shows nothing. No connections are listed and if I click on New Connection, I'm told that "Bluetooth is not ready."
Nonetheless, I am Hotsyncing successfully!!!
The first try, (after going to generic drivers and thus actually being able to "Pair Devices" via the Bluetooth Devices window) seemed so slow that I may have given up prematurely.
I finally hit "Cancel" on the Palm device, which seemed to hang forever and not be able to get out of that loop, so I forced a shut down via the power off button.
Then I also had to to a Ctrl-Alt-Delete to force the HotSync to shut down on the PC as well.
I did a soft reset of the PalmZire and I restarted the PC after that. The next time I tried to HotSync, it didn't hang on Step 1 (of 12) even though it WAS VERY SLOW. I have a LOT of appointment info etc that I save and there was a lot to have sync for the first time on this PC.
I got a message that this device (the Palm) had synced before on another PC, and did I want to allow this to proceed since it might create lots of duplicates. I chose to let it go ahead. It did create a fair number of duplicate appointments, but mainly on in the repeating appointments type. I just went through these in Outlook and deleted one of each duplicate, deleting the whole series when I did. The next HotSync went very fast, and cleaned all these duplicates up on the Palm as well.
I have not restarted again yet, and I am not sure all is going to remain in place, but I know now that I can probably make it work out. The lack of anything listed in the Bluetooth Settings window on my PC does concern me, but I'm hopeful it won't be an issue. I don't expect to use Bluetooth for anything else, at least for now.
After all the hours I have fussed and read and griped, I am hopeful I have it worked out. I strongly suggest reading the thread mentioned above about HotSync solution found, but in addition to the other factors you have to address, remember to try changing drivers if your bluetooth doesn't work right away. (If it does, consider yourself HIGHLY BLESSED!)
Well, I gotta quit this short novella and go to bed, but I hope this helps someone else manage to set up bluetooth on a 64-bit VISTA system.
How in the world does anything as helpful as a PALM go out of business? It must have taken a lot of concerted effort by management to destroy the future of such a helpful piece of hardware!
Hang in there, Zire; I need you to keep working till a suitable alternative comes along. I doubt it'll be a Crackberry!
Dale
Post relates to: Zire 72

Further notes: When I allowed my PC to come back up from a Hibernate state, there was an error message waiting for me that said something like Port 5 is busy; Will wait till port is open" or something like that.
However, the Port I had been using (that I created for HotSyncing) was Port 8, which had worked. I don't know why this happens, but it seems to repeat itself if I do not do a clean boot.
As long as I restart the PC or boot from a shut-down state, my adapter seems fine and Port 8 is available and does work for the HotSync.
It was VERY slow on the first HotSync that had to run MANY procedures and lots of calendar stuff, but now the HotSyncs are SO FAST. Much faster than they were with the USB and Windows XP.
I have now turned my Firewall ON and it does NOT affect the HotSync. (I DID go into the Firewall setup and added Bluetooth Settings, HotSync Manager, and Palm Desktop to the exceptions list to ALLOW these through the Firewall.)
My antivirus program also does not seem to cause any problems for the HotSync, even though it does have to interject itself each time the Outlook data gets accessed. It just verifies that there is no virus activity going on, so it makes a momentary pause as Outlook info is updated.
I also have found that the HotSync runs fine whether Outlook is already open or not.
So far, I'm quite happy things are smoothing out!! Let's hope it continues.

Bluetooth device detection

Hi everyone!
(I am newb at Java, and im looking for a very simple application (i think), but im not sure how to find what im looking for, i tried sourceforge.net, but i dont know how to run the java source files.)
What im looking for is an app for PC that searches for bluetooth devices in the area, and logs their MAC address into a file (preferably .xml)
It should continuously search for devices, and update the .xml file everytime it finds a new device, or an old one dissapears, so i always know what devices are in the area at this excact moment.
Have you ever heard of such a thing, or do you simply have some good keywords for me to use :) Either way i would be very thankful for your help! :)
Cheers,
Lars

Ok, here is my code a bit more formatted:

while (!done) {

    try {
    thread.sleep(DISCOVERY_LATENCY); //2000ms
    } catch (Throwable t) {}
* Start a new Device discovery
synchronized public void doSearch() {
try {
//get local bluetooth device
local = LocalDevice.getLocalDevice();
//get discovery agent
agent = local.getDiscoveryAgent();
//start a new Bluetooth discovery inquiry
agent.startInquiry(DiscoveryAgent.GIAC,this);
//we lock the thread and wait the end of the current inquiry
synchronized(lock) {
    try {
    lock.wait();
    } catch (InterruptedException e) {}
} catch (Exception e) {}
*We detected one bluetooth devices
public void deviceDiscovered(javax.bluetooth.RemoteDevice remoteDevice, javax.bluetooth.DeviceClass deviceClass) {
try {
// get the bluetooth MAC address of that device and remove any white space
String value = remoteDevice.getBluetoothAddress().trim();
if(checkTable(value) && doneDetection == false)
doneDetection = true;
launchHotSpotPage("test");
} catch (Exception e) {
System.err.println("BLUETOOH ERROR");
* The bluetooth discovery inquiry has been completed
public void inquiryCompleted(int discType) {
local = null;
agent = null;
//We unlock the thread in order to make a new discovery
synchronized(lock) {
try {
lock.notify();
} catch (Exception e) {
System.err.println("BLUETOOH ERROR");
lock = null;
