BlueSoleil is the setup software bundled with many Bluetooth adapters. Its advantages are intuitive interface and strong compatibility.This is the latest version 2.0, with Chinese instruction manual attached.An important upgrade of this version is EDR (enhanced data transmission rate). EDR increases the speed of Bluetooth to 3Mbps. The advantages of EDR are: 1. Higher bandwidth to support simultaneous connection of multiple devices.2. Better audio quality.3. Lower power consumption.In a multi task environment (the host is connected to the keyboard, mouse, and headset at the same time), if a mono headset is used, the bandwidth margin of Bluetooth is only 42%, which will not allow data retransmission, otherwise the audio quality will be affected;If stereo headphones are used, the bandwidth margin is only 25%, which is not enough to support other applications, such as file transfer.With higher bandwidth, EDR can better support simultaneous connection of multiple devices and provide better audio quality.In the same multitasking environment as above, the bandwidth margin of EDR is 62%, which is enough for other applications.In addition, when transferring files of the same size, EDR only needs the first 1/3 of the time, thus saving power consumption.Of course, this requires your Bluetooth adapter to support EDR to achieve such improvement.Generally, Bluetooth 2.0 adapters support EDR, so it is strongly recommended that those who have Bluetooth 2.0 adapters and like the BlueSoleil driver upgrade.It doesn't matter if your Bluetooth adapter is not 2.0. This version also supports your Bluetooth 1.1 and 1.2.Installation instructions (please follow the following sequence, or a blue screen error may occur during installation): 1. Uninstall your original Bluetooth driver first, and unplug your Bluetooth adapter.2. Restart your computer and install the new Bluetooth driver.3. Start your computer again, plug in your Bluetooth adapter, and start your new Bluetooth journey.
