This simple USB adapter acts as an antenna for your computer, giving it Bluetooth capability. This bluetooth dongle comes with a full version of BlueSoleil software and drivers. However, the software is not licensed to every type and model of hardware that is capable of using Bluetooth.

To overcome that limitation, users must purchase a different version of BlueSoleil software separately. We apologize for any inconvenience.
