Build a wireless LAN through Bluetooth

The bluetooth gateway is connected to the LAN access interface through the RJ45 plug. The personal computer and various devices must be equipped with a Bluetooth universal module or a Bluetooth Nic for Bluetooth. The maximum straight line between the bluetooth gateway and each terminal cannot exceed 100 m, and a bluetooth gateway can connect up to seven devices with universal external modules.

In the networking scheme, the main components have the following functions:

1. bluetooth gateway (LLTR-1S)

◆ Use time division multiple access technology to support asynchronous data and point-to-point Bluetooth data communication;

◆ Interfaces and capabilities for communicating with wired networks and Bluetooth devices at the same time;

◆ Implement address explanation between the Bluetooth address and the IP address based on security;

◆ Implement the IP Internet protocol and the TCP transmission control protocol, so as to complete the conversion between the Bluetooth protocol and the TCP/IP protocol;

◆ On the basis of the underlying protocol stack, a specific Bluetooth routing mechanism is implemented to solve the routing problem between networks, and ultimately solve the communication problem between different bluetooth networks and different units.

2. network adapter (BlueBerry Bluetooth USB)

Install it on PCs and laptops in the network to enable Bluetooth.

3. In order to provide Bluetooth functions for office printers, projectors, scanners, and other office equipment, the universal Bluetooth module of jinou company is selected, the universal Bluetooth module provides a serial port, USB port, and parallel port.
