How to ActiveSync using Bluetooth instead of USB Cable

Posted on Apr 15 2009 - 2:13pm by mrwangkai

Connecting USB Cable during each ActiveSync can be a troublesome task if you need to perform it multiple times a day. There is however a way to setup the task wirelessly by establishing the ActiveSync connection through the built-in Bluetooth on your Windows Mobile device.

This process can be breakdown into two parts, one to be done on the PC and the other on the Windows Mobile device. We will first look at it from the PC side:

Note: This process has only been tested out on Windows Mobile PocketPCs.

Processes on PC

Step 1: Locate Bluetooth Configuration and the COM Port:

  • You may find it in the system tray with the Bluetooth logo, or
  • Control Panel > Bluetooth Configuration > Local Services tab

Bluetooth Configuration: The Port number is 7 in this scenario.

Step 2: ActiveSync Setup

Before we begin, please make sure the mobile device had previously been synced with the PC through ActiveSync.

Next, open up the ActiveSync and go to File > Connection Settings

Go to the following path: File > Connection Settings

Under “Allow connection to one of the following” be sure to choose the port that the Bluetooth is assigned to. In our case, it’s port 7.

Choose COM7 from the drop-down box to assign connection to Bluetooth.

Processes on Windows Mobile

Step 1: Turn on Bluetooth on both the mobile device and your PC

Step 2: Go to the Bluetooth Setting on your mobile device and select your Computer. If unavailable, perform a search of Bluetooth devices by clicking “Add New Device”.

Step 3: Next, the Partnership Settings page will appear on your mobile device listing the service to be included (as shown below).

Choose ActiveSync and OBEX File Transfer for services to be used.

Step 4: Open up the ActiveSync application on your mobile device and through Menu, choose Connect via Bluetooth.

Step 5: Finally, once the connection is establish, simply click on Sync to sync between your PC and the mobile device.

You are good to go, no more messy wires!

    I have spent dozens of hours trying to get my Ominia II WM6.5 (New in Dec09) to ActiveSync with my IBM T60 XP SP2. I followed the above instructions to the letter several times to no avail. In my case I found the problem to be on the IBM laptop. I have found that I have to disable and then immediately re-enable the COM service in MY BLUE TOOTH PLACES on the PC. I have to repeat the Disable/Enable process each time I start the computer including from hibernation. This is disappointing but at least I can now use BT with Active Sync. No more cables Hurray!!

    @P, we will try to re-construct the situation (syncing thru BT). Hopeful we can figure something out.

    I managed to set up a sync partnership between the desktop and the mobile phone. Both places detect each other, show the ActiveSync service, etc., but when I try to sync, the phone scans for a while and then says no devices are present and no partnerships are set up (right after I set it up!) Then it asks me if I want to try another device. So I select the PC from the list again (it’s the only device available), and it does the same thing. A COM (I tried the entire range from 2 to 9) port was assigned on the PC but I can’t do it on the phone. The entire COM port section in the Windows Mobile ActiveSync is disabled and the registry entries listed in various posts/articles don’t exist in my registry (Windows Mobile 6.1)!

    Still, the device claims it’s paired to the PC, and the PC claims it’s paired to the device – I get the icons, check boxes, etc. I even tried transferring a file, successfully, over the Bluetooth connection (it’s turned on to accept any connection and remain visible). But when I try a sync via BT, it just says there’s nothing available (then goes on to display the available device!!!)

    I created the original sync partnership using a USB cable and followed the instructions to the letter so this is really bothering me. The pairing seems to work just fine, but the sync fails like the device isn’t connected to anything, and a number of the settings (especially COM) on the mobile device are either unavailable or just not there.

    If anyone at all has even an idea, I’d LOVE to hear it!

    I have followed the instructions, it works great on my omnia, no more hassle of connecting the cable!

    Figured the Access Denied thing–had a bad copy of a registry editor. Anyway, changed the com ports on the phone in the registry two of the ones the computer had and tried that but the phone now says it “The com port could not be created.”

  8. Thumper May 5, 2009 at 10:34 pm -

    I downloaded Mobile Registry Editor and went to HKLM->Software->Microsoft->Bluetooth->Serial->Ports->SupportedPorts and tried to change the Com ports but it won’t let me. Telling me Access is Denied. What am I doing wrong?

  9. Mike April 30, 2009 at 8:47 pm -

    i finally figured figured it out. i am using xp.

    first i deleted the pairing from my device and on the laptop.
    i even deleted the partnership in the active sync.

    after that i again followed the instuctions above and finally active sync is there in my omnia.

    i reconnected the cable first to set-up initial active sync.

    by the way, it doesnt matter what com port your pc/laptop uses. as long as you indicate the com port that the bluetooth uses

    succeeding syncs are now done through bluetooth by going to active sync in my omnia then pressing connect via bluetooth. and thats it.

    hope this helps.

    And there is another tip which might be more appropriate.
    You can add COM port you desire at

    You can change the COM port to COM7 you want.

  11. hansoo April 30, 2009 at 3:21 pm -

    Why don’t you try the following. It is how to reset com port.

    1. Using a registry editor for the mobile phone, open the branch “HKLM\SOFTWARE\Microsoft\Bluetooth\ActiveSync”
    2. Delete sub-folders (I had two with a hex-String like this “000a3xxxxxxx”)
    3. In the \ActiveSync folder delete the “LastConnected” Value and set the “Initialized” value to “0”
    4. Delete any existing pairing with the computer you want to sync with (both on the phone and on the comuter, if necessary)
    5. Verify (as most other solutions to this problem suggest) that the BT serial port (as found in your BT control panel on the computer) is the one ActiveSync (again, on your computer, under File>Connection Settings) is listening on (i.e. BT serial port is COM5 and AS is set to accept connections on COM5)
    6. Establish a pairing with the computer from the phone’s BT settings – once you have successfully paired one of the services on the computer should be ActiveSync (if it’s still not, I don’t know what to do for you)
    7. From AS on the phone, select “Connect via Bluetooth”. You may have to allow the serial connection on the laptop the first time.
    8. Voila! (hopefully)

    A couple of notes about this:
    First, I had previously been connecting successfully with ActiveSync on Bluetooth but had to switch to a different USB dongle to support my BT GPS. I think that’s why I had outdated AS settings on the phone that were screwing me up. I suspect that if you are trying to sync your device for the first time this won’t help you.
    Second, I had already gone through all the registry settings on the computer and BT settings to verify that the BT serial port was configured correctly as was ActiveSync on the computer. I didn’t go through all that here because those steps are outlined ad nauseam on many boards.

    BTW: props to SomeGeek on for pointing me to this solution – I’m just passing it along to a bunch of the other places I looked for answers

    I know how to delet the profile on the phone but when I am in my bluetooth floder I can unpair the phone but it won’t let me delete the profile. How do I do that in XP?

  13. Thumper April 30, 2009 at 11:47 am -

    I have tried doing that already and it still only gives me Com 2 and 6 as port options on the phone.

  14. hansoo April 30, 2009 at 11:27 am -

    I’ve experienced the same issue. However, after pairing again it works properly. When you re-pair them, you need to delete profiles on both PC and Omnia clearly first.

    Good luck.

    I am using xp i have followed everything. i also cannot connect. the problem i think is that i cant see the active sync services (partnership settings page) in my mobile device (samsung omnia). no matter how i refresh it it doesnt show.

  16. Thumper April 29, 2009 at 5:40 pm -

    I am using XP Professional

  17. admin April 29, 2009 at 5:12 pm -

    @Thumper, the instruction is different on Vista or other OS than XP. May I know which OS you are using? (If Vista, you can actually Add Com Port to match that of the ActiveSync). Thanks!

  18. Thumper April 29, 2009 at 4:33 pm -

    The Computer will set up Com ports for the Serial port on 3, 5, 7 etc. But the phone wants to do it on Com 2 or 6. I don’t know how to change the Com ports on the PC or the Phone.

  19. mrwangkai April 28, 2009 at 5:35 pm -

    @Thumper, I think the best way is to accommodate one for the other. In this case it seems easier to setup the COM port on the PC than on the ActiveSync. Can you try to modify the property for the Bluetooth port on the PC, if that doesn’t work, see if you can add the Bluetooth again as the serial service.

  20. Thumper April 28, 2009 at 5:29 pm -

    I have not been able to connect to Bluetooth on my computer to do an activesync. My Epix finds and connects to the computer but only allows me COM ports 2 and 6 as options while my computer doesn’t give me that option. What do I do?
