If you control the Bluetooth module by a computer, you need to use a USB to TTL serial port module to convert the interface. This driver is only a USB to TTL serial port cable driver and has nothing to do with the Bluetooth module (you don’t need to install it when you don’t need the USB to TTL serial port module). After the USB cable is plugged into the computer, you will be prompted to install the driver. Double-click CH341SER_V3.3[2012-02].EXE to install the driver.
