Embodiment Construction

[0015] figure 1 It is a schematic diagram of the hardware structure of an embodiment of the Bluetooth-WIFI gateway. As shown in the figure, the Bluetooth-WIFI gateway consists of several hardware units. The central processing unit (4) is the calculation and control core of the Bluetooth gateway, and completes all program operations in the gateway. The central processing unit (4) is connected with the bluetooth module (5) through the serial port, and the bluetooth module (5) is connected with the bluetooth antenna (9) through the radio frequency port. The bluetooth antenna (9) is used for sending and receiving wireless signals. The memory RAM (8) is connected with the central processing unit (4) through a bus, and is used for storing programs and data when the central processing unit (4) is running. Flash memory FLASH (7) is connected with central processing unit (4) through bus line, is used for storing data information. The central processing unit (4) is connected to the ...

Abstract

The invention provides a Bluetooth-WIFI gateway enabling a Bluetooth device and a WIFI device to be communicated transparently. A central processing unit is connected with a Bluetooth module and a WIFI module through serial ports and is used for converting and transmitting converted data of the Bluetooth module to the WIFI module or converting and transmitting data of the WIFI module to the Bluetooth module. The Bluetooth module of the gateway is communicated with a Bluetooth terminal through a piconet. The WIFI module and the WIFI device of the gateway are communicated through a wireless network. A protocol model of the Bluetooth-WIFI gateway comprises a Baseband, a link management protocol (LMP), a logical link control and adaptation protocol (L2CAP), a Bluetooth network encapsulation protocol (BNEP), a service discovery protocol (SDP), a Physical layer, a Datalink layer, a Network layer and a Transport layer, wherein the Baseband, the LMP, the L2CAP, the BNEP and the SDP correspond to Bluetooth, and the Physical layer, the Datalink layer, the Network layer and the Transport layer correspond to WIFI. A routing layer of the Bluetooth-WIFI gateway is upmost. The Bluetooth-WIFI gateway is provided with the virtual Bluetooth device and the virtual WIFI device, and existing routing mechanism is changed appropriately so as to achieve the communication between the Bluetooth device and the WIFI device.

Description

technical field [0001] The invention relates to a gateway for realizing transparent communication between a Bluetooth device and a WIFI device, and belongs to the field of embedded technology and communication. Background technique [0002] Gateway (Gateway), also known as Internet connector and protocol converter, is a computer system or embedded product that acts as a conversion task. A gateway is an important network device that realizes the interconnection of a wide area network or a local area network at the transport layer. The gateway provides network compatibility functions such as protocol conversion, routing selection, and data exchange when intercommunicating between networks using different architectures or protocols. During data conversion, the gateway repackages the data according to the source-end protocol and the destination-end protocol. The technical implementation of the gateway is relatively complicated, and it is a product combining hardware and softwa...
