Abstract
A Bluetooth pairing system includes an external device and a host device. The external device includes a Bluetooth module, a first transmission interface and a USB controller. When the external device is connected with the host device, a standard handshaking message complying with a USB communication protocol is issued from the processor to the external device. After the standard handshaking message is received by the USB controller of the external device, a device descriptor of the external device is transmitted from the USB controller to the host device. The device descriptor contains a vendor identification code, a product identification code, a product string and a product type of the external device and a target communication address of the Bluetooth module. The host device analyzes the device descriptor to acquire the target communication address of the Bluetooth module.
