No Activesync In Vista I don’t know if you guys can help me with this problem…It may be an problem with active sync(Windows Mobile Device Center) in Vista Home Premium. I am using an IO Gear GBU 221 Bluetooth adapter to connect from my home PC(HP Media Center PC m7350) to a Motorola Q smartphone(Sprint). The Bluetooth connection is working well. I can see the phone fine in the Bluetooth menus and transfer files to and from my PC via Bluetooth. I have no problems connecting my PC to the Personal Area network or to a Jabra Headset. My problem lies when I try to use active Sync. Windows Mobile device center does not see my Smartphone. When I’m in Active sync on the phone I can click Connect via Bluetooth to add a new sync partner, I then search and find the name of my home computer and hit select. This is where the problem lies. It says Checking services for about 10 min then Bluetooth ActiveSync Service not found. “The service you are requesting is not supported on the device. Please make sure the device is ready and the service is enabled.” I tried the following registry edit but I can still not activesync through Bluetooth. http://mobilitytoday.com/forum/showthread.php?t=15245 one of the problem that I get after migrating to Vista is getting Activesync to work using bluetooth. For some reason, Windows Mobile Device Center (WMDC) doesn't allow bluetooth synchronisation to work especially, and I suspect it's because WMDC assume bluetooth service discovery, pairing & connection process that's not based on (bluetooth) virtual com port. In anycase, selecting 'Bluetooth' in the WMDC's connection setting doesn't work, at least for me. This is because while my mobile device detects my desktop via bluetooth, it cannot determine there's an activesync service (i.e. WMDC) running in the background in the desktop. In the good old days of Activesync, all I need to tell activesync to 'listen' to a bluetooth com port. There's no such ability in WMDC. This registry hack, to be applied to your desktop pc/laptop, enables WMDC to bind to a bluetooth virtual com port (as you set this com port as the incoming port). Go to \HKLM\Software\Microsoft\Windows CE Services, modify the value name "SerialPort" from "Bluetooth or Infrared" to "COM4", where COM4 is the virtual com port associated to your bluetooth incoming com port. The number varies from desktop to desktop, so choose the right com port for your specific use. I have updated my phone via Motorola and updated WMDC and IO gear to the latest software versions as of 3.14.2007. The USB SYNC works fine, I feel like I’ve tried everything I can think of. Any help would be greatly appreciated.
