The Avantree DG40S supports a newer Bluetooth standard, namely Bluetooth 4.0. Bluetooth 4.0 is particularly energy efficient for both the receiving device and the device that needs to be connected if it also supports Bluetooth 4.0. To be able to use the full range of functions of the DG40, a driver CD was included in the scope of delivery, on which the software "BlueSoleil" is located. This is a so-called "Bluetooth Stack", ie a driver that has a much greater functionality than the standard Windows driver.
The range of the DG40S is approximately 50m. All types of devices can be connected, from audio devices to input devices. As an audio profile, the dongle uses A2DP, which ensures a decent sound.
By the way, Bluetooth is backwards compatible. Bluetooth 1.1-4.0 are supported by the dongle. You can also connect several devices at the same time.
The included software is easy to install and also the dongle is set up almost automatically. The software also has a user-friendly interface. You simply have to select the appropriate device based on the icons, what you want to connect and the rest will be done by itself.
