Bluetooth connection problem with Samsung A640 and Microsoft Sync

I have had my Samsung A640 since last year and had no problems using bluetooth with other devices, but we just got a 2008 Ford Focus that has Microsoft Sync and at first when pairing devices, it worked great. Now there are times where my bluetooth phone does not connect with Sync, even though I have the visibility set to "always visible" and bluetooth enabled. There are also times where the phonebook download fails, and then other times where the phonebook downloads just fine.

I really am not sure if this is a Samsung A640 issue or if it is a Sync problem. There is no real support on the Sync website. Any help would be greatly appreciated.

Hi, once these are dropped in water or soaked, they,re in the Bin.
All you can do is This.
1:) remove the Battery.
2:) put the phone ( without as much casing as possible ) on A central-heating Radiator. On top of a towel.
3:) gently blow with a warm-hot set hair Dryer.
4:) replace Battery and switch on.
If non of this works, bin the phone, and give your son a clip around the ear :)

Is the bluetooth on Capella sleep and sound alarm clock, CR50, compatible with an Android samsung galaxy s4? I can't get it to pair

Samsung Galaxy S4: Trying to pair by Bluetooth to Capella CR50 Desk clock: Unable to pair:


Yes, the Capella CR50 should be able to Bluetooth pair with any device that can connect via Bluetooth (as stated in the Capella product description).

If you are not able to connect try doing the following (process of elimination) to resolve why this is happening:

  • Turn off and turn on again Bluetooth mode
  • Try resetting the Bluetooth app in Applications>All Applications under Phone Settings
  • Try eliminating apps that may be affecting the bluetooth connection.. you can narrow this down by rebooting the phone into Safe Mode. If in Safe Mode, your S4 is able to connect via bluetooth to the Capella CR50, that will tell you that it is software related, and most likely an app that you installed that is not playing nice with your phone. You can either remove apps one by one and retrying to connect via bluetooth to find and eliminate the issue, or remove all the apps you installed and start fresh.
(Note: removing an app with erase any settings you set up as well as any database within the app (such as a game with scores/levels/and any rewards you received/purchased, unless that database is saved in an online cloud account you sign into specifically for that app, or sync to Facebook (FB) while having the game installed in your FB account

Here are the steps:
1. Make the partnership between the phone and the pc with the cable first and let it sync once.
2. Unplug the cable, turn on the bluetooth and make the pc and phone connect through bluetooth and save the device in the device list so it can connect everytime you want to sync without adding the device again.
3. Once they are connected to each other run active sync (with bluetooth still active) and press Menu-Connect via bluetooth. Here's the tricky part, it wont always connect. You have to do this a couple of times until you get a connection. For me its like 4-5 times and i get connected.

Thats it.

Palm TX, Dell 6300 Laptop, can see each other through Bluetooth but will not connect. Want to connect to sync clocks.

Have you checked your hotsync settings and bluetooth settings to make sure that you are using bluetooth sync and not the serial connect. Palm devices can also share LAN/Internet over bluetooth.

removing the bluetooth is as simple as this:

menu, settings, connectivity, bluetooth, my devices, press down to get to the device you want to delete, press options, then delete.


menu, settings, connectivity, bluetooth, my devices, (should have at the top: search for new devices scrolling). Click that:

h700 bluetooth should be in pairing mode:

hold the center button down and wait for it to turn solid blue: the go back and search for new devices on the phone, when it finds the bluetooth, enter 4 0000 zeros for the passcode. The click if you want it to automatically connect or not.

Your done!
