Please check the following items:
 

1. Verify whether the remote device is within the radio range.
2. Verify whether the remote device is in connectable mode. If the remote device is set to non-connectable, other devices cannot connect to it, and service cannot be found.
3. Check whether the remote device has connections already. Currently, some Bluetooth devices do not support multiple connections.
4. Verify whether both sides have input the right Bluetooth passkey, generally before making a connection you need input the same number such as "1234" on both sides to pair them.

BlueSoleil version 10 needs  serial number to activate and it is not free.

1. Minor versions (1.1, 1.2 etc.) are free to registered customers because they contain only small functional improvements and defect fixes>>
2. Major versions (7.0, 8.0 etc.) are chargeable because they represent significant upgrades in functionality that require investment of time, money and resources to design, develop, test, document and publish the new features. We will ensure that customers get value for money and a well-rounded new product for each major version.

There are 4 possibilities:
 

1. You didn't insert a Bluetooth Adapter; please make sure you are using a dongle or CF card.
2. Your dongle was not inserted properly, please un-plug it and then re-plug it to have a try.
3. BlueSoleil was not installed properly. Please make sure that you didn't install the driver from Microsoft and reinstall BlueSoleil.
4. Your OS doesn’t recognize your Bluetooth Adapter, neither does BlueSoleil. You can change another adapter and retry to make your PC recognize it first.

It's a prevalent confusion for users. IVT Corporation is only the Software Product BlueSoleil provider, Not the Hardware Dongle maker, we supply BlueSoleil basic versions such as BlueSoleil 2.x to Bluetooth chip makers worldwide. Then chip makers bundle their Bluetooth chips with BlueSoleil to USB dongle makers. USB dongle makers supply Bluetooth USB dongles to worldwide market. We do have an ecommerce site on www.BlueSoleil.com to sell dongles with brand name "BlueSoleil" and these dongles are well checked and licensed one by one.

Bluetooth passkey is used in authentication procedure for Bluetooth security purpose. When remote device connects to your computer, he has to offer the same Bluetooth passkey as what you input such as "1234". If the Bluetooth passkeys from two sides are the same, connection can be set up. A paired relationship is established on both sides. There is no need to input passkey for the next time of connection. Either side can delete the paired relationship.
In addition, for those Bluetooth devices that don't have input configuration such as headset, you can only input the passkey which is a default on the computer side, you can generally find it on the cover of the package for your Bluetooth device or you can check the user manual of your Bluetooth device.

BlueSoleil can just find the services which your Bluetooth device supports and enables. None of Bluetooth devices will support all profiles.

This problem has been fixed in BlueSoleil version8.
If your bluesoleil version is lower than 8.0.376.0, please update your bluesoleil to version 8.0.376.0 or above.

There is one option for you to have a try:
