Hi,
I am developing an application that will draw multiple figures like rectangle, circle,square on a canvas.I want to send this via bluetooth to other device.In which format should i send this?How?
Thanks

You will need capture the screen. Steps are
1) Create Image of the size of your canvas.
2) Get graphics object for this image using getGraphics() method of Image.
3) Whenever you draw on the canvas, also draw on this image using the graphics object you obtained from Image.
4) Use getRGB() method of the image to grab the pixels.
Use JSR 82 to transfer this data over bluetooth.

    transfer of photos from ipod to ipad via bluetooth, help

    The blluetooth isn't meant to do that. It's largely meant for headphones and keyboards.
    now, if you have the camera connection kit  you can attach your iPod to your iPad using that (plugging the iPod's charging cable to the USB part of the CCK) and the photos will transfer. I've done it with my Touch.

    The only way that you can connect your iPhone to the mac is to use it for a "Wi-fi hotspot" meaning that you can use the celluar connectivity of your phone to connect your computer to the interent.
    Do you mean a MacBook Pro of the desktop MacPro?

  • How to transfer files to and from iPad air using bluetooth

    How can I transfer file to and from my iPad using Bluetooth to another Bluetooth-enabled device?  Is there an app for this? 

    iOS devices do not have the Bluetooth profile for file transfer. Even if the other device is a an iOS device, you can't transfer files over BT. You can use Airdrop between iOS devices. However, even though Airdrop uses BT to locate other devices, the actual transfer is done over WiFi. There are some apps in the App Store that, if loaded on both iOS devices will allow limited file transfer over BT between the devices.

    You don't. File transfer, by Bluetooth, has never been supported on any iPhone.

    I`ve connected iphone with macbook pro few weeks ago for i-net surfing, but i had to use cable. Now i wanna try icloud, and i`ve faced that trouble.

If i try it with iphone, a message "mbp cant be connected, it isn`t connectible device"-something like this- appears and mbp disappears from known devices list. How can i solve that?
    MacBookPro8,3 (17")-june 2011

    I have somehow the same problem. I just bought the new iPhone 4S and tried to connect it to my MacBook Pro (OS X 10.6, latest version, model 2011). The Phone did not see the Mac but the Mac the Phone, so I connected the Phone via Mac.
    It worked for about 5 seconds, but then I got this error message:
    It's German and means that the network is not available.
    Of course I tried again to connect, but I now get always this error:
    It says that the device is not available...
    I deleted the iPhone from the list under Mac and tried again, but it's still the same.
    No my Questions to the community:
    Why does the iPhone not see the MacBook?
    Why does it allways disconnect?
    Is Sync not possible via Bluetooth?
    Thanks for your help!

  • How do I connect my Centro to the Internet via bluetooth over PC's Internet? Where is Centro's PPP Connection Type? How do I setup Login Script for bluetooth connection?

    I am trying to set up bluetooth on the Centro to connect to the internet via my PC's internet.
    HotSync over bluetooth works successfully.
    Computer specs: Toshiba P205-S6277; Bluetooth Stack v5.10.04 (currently using); Bluetooth Monitor v3.01 (to use Vista's built-in bluetooth)
    I think I have narrowed my problem down to 3 things.
    (1) Finding Network Access properties (to allow connected devices to access the internet)
    (2) Finding Centro's Network Connection Type: PPP
    (3) Finding the correct Login Script to use
    for (1) I think I've looked everywhere; found nothing on Network Access. 
    Checked control panel: only Bluetooth Local COM
    Right-clicked bluetooth icon > Settings: File transfer, PAN Networking, PAN DHCP server, AV controls. Other bluetooth settings are for file transfer or object push. I don't see anything like this.
    I'm stumped on (2). It seems as if palm removed this option under Centro's Advanced network settings .
    Nearly all the forums that I read says to choose Connection Type: PPP.
    (3) Found 2 scripts that seemed would work. I don't know how it exactly works but it sounds workable.
    First script:
    Send: CLIENT
    Send: CLIENT
    Wait for: CLIENTSERVER
    End:
    Script 1 Connect Log:
    =======================================
    Connect Log
    S: client
    S: client
    R:
    Err: 0x121F   <<<netErrUserCancel b/c I canceled it. 
    Not connected
    ========================================
    I canceled it because the process would stay on "Signing In" then it automatically "Canceled" itself.
    Second script:
    Send CR:
    Delay: 1
    Send: CLIENT
    Wait For: CLIENTSERVER
    End
    **UPDATE** I found on this forum (Reply # 3689) that the script is needed only if you are using Palm OS 4 or under. Centro uses Palm OS 5.49121. Can anyone support this?
    Even without the script it has problems "Signing In".
    I'm currently reading this site and trying out its decribed methods. I will update this thread when I get the results.
    I'm using the Centro. And If anyone's been able to successfully connect to the internet on the Centro via a bluetooth connection to the PC WITHOUT 3rd party applications, please share.  If not, please share any ideas.
    Thanks!
    -Eric

    I've been going at this for days, and have probably exhausted all the proposed solutions on the first 3 pages of various google searches. I'm getting the feeling that Vista users are pretty much SOL for the time being.
    For the record, I just tried out a few of the solutions (mRouter & SoftickPPP) on XP and they work perfectly.

  • How to connect between th iphone 3 and ipad4 via Bluetooth ? (it does not work)

    This is done in order to use the 3G via the iphone.

    If your carrier doesn't support it then there probably isn't much that you can do about it (if you want to stay with your current carrier). You can get mifi devices (effectively a mobile 3G router) which you can use with iPads, laptops etc, and they also use a sim card so you could consider getting one of those - I haven't got or used one so I can't comment on how good they are, and I don't know whether you have to go for a subscription with them or whether they can be used on a 'pay as you go' basis if for example you wouldn't be using it that much.

  • I am new to iphone., want to transfer some files from my LG  KM900 via bluetooth, having trouble pairing, is it possible

    Hi there,
    New to the iphone, and love it, but I would like to send a couple of files and photos to it from my previous phone via bluetooth... My previous phone was an LG KM900 and im having difficulty pairing with it... saying its not supported.,
    Can someone give me a list of compatible bluetooth(able) phones, and i will do it through a third party...
    Many thanks and I do hope there is a way to do this
    regards
    Debz

    This is not a feature of the iphone or iOS.
    Bluetooth is supported for stereo headsets/speakers, handsfree telephone
    devices/headsets, some keyboards, some peer-to-peer apps from the app
    store and internet tethering where provided by the carrier.
    Other than this it will not connect to a phone/computer/device.  (thanks to ckuan for the wording)
    You could try emailing the files/photos from the LG and then open the emails
    on the iPhone. Depending on the type of file, the iPhone should be able to at
    least view the contents - editing will require an app capable of dealing with that
    particular type of file. Photos should be viewable unless in proprietary format.
