Problems solved by technology

At the same time, the communication software on the mobile device side is also rapidly popularized. The existing communication network communicates by accessing the mobile communication network provided by the mobile operator. The access methods are generally GPRS, WIFI and including TD-SCDMA, CDMA2000, 3G communication technologies including WCDMA, these communication technologies also have their disadvantages: First, these communication methods rely on pre-set network access points. Once the network facilities are damaged, the devices in the network will not be able to communicate
Using Bluetooth technology, wireless communication between mobile devices can be easily and effectively realized, but the effective communication range of Bluetooth is very short, and connection and communication cannot be performed beyond a certain distance, and a Bluetooth master device can communicate with up to 7 slave devices at the same time communication
It cannot carry more users, and the Bluetooth connection process is cumbersome to set up. Both devices need to be active at the same time to discover each other, and multiple parameter settings are required to achieve communication.
Nowadays, it is often used to establish WIFI hotspots to provide networks for other mobile devices, and use this hotspot to build a WIFI-based wireless local area network. The WIFI network has a large distance and no limit on the number of connections. However, compared with Bluetooth, the transmission quality of WIFI is very poor. Well, the signal is unstable, the packet loss rate is high, and the security performance is relatively poor
Moreover, the power consumption of WIFI is huge, which is unbearable for mobile devices

Embodiment Construction

[0038] Below in conjunction with accompanying drawing, the present invention is further described in detail:

[0039] The present invention relates to a method for ad hoc networking and communication of Android mobile devices based on bluetooth, specifically comprising the following steps:

[0040] Networking steps

[0041] First, the mobile device starts Bluetooth, searches and obtains the names and MAC addresses of surrounding Bluetooth devices. Specifically, the mobile device calls the BluetoothAdapter.getDefaultAdapter() method to obtain the local default Bluetooth adapter operation class BluetoothAdapter. Support Bluetooth; otherwise, when the Bluetooth function is found to be disabled, such as calling the settings to enable Bluetooth. If it is found that the current device has not opened the externally visible mode, call the open discoverable mode by passing the method of Intent; then call the startDiscovery() method of the BluetoothAdapter class to perform an asynchron...

Abstract

The invention relates to a bluetooth based networking and communication methods for Anddroid mobile equipment . A networking method includes (1), searching and acquiring surrounding bluetooth device names and Media Access Control addresses; (2), matching connection and exchanging found surrounding device number information; and (3), connecting surrounding devices and forming an original routing list. A communication method includes that the mobile devices detects information of the routing list and calculates the distance from a target device; and if the target device is directly connected with the mobile device, then message information can be directly sent out; and if not, the message information can be sent to devices adjacent to the mobile device, and then be sequentially sent to the target device. Compared with the prior art, preset network facilities are not required with the new message-sending method based on the bluetooth; the method has good adaptability and practicability rebuilding processes, and the rebuilding process is totally transparent without manual parameter configuration or setup; and communicating distance range is broadened.

Description

[0001] technical field [0002] The invention relates to a networking method of a local area network, specifically, a Bluetooth networking communication method based on an Android system. [0003] Background technique [0004] With the intelligentization of mobile devices and the development of mobile communication networks, mobile devices have changed from an ordinary communication device to a portable microcomputer integrating communication, Internet access, personal transaction processing, multimedia playback and game entertainment. At the same time, the communication software on the mobile device side is also rapidly popularized. The existing communication network communicates by accessing the mobile communication network provided by the mobile operator. The access methods are generally GPRS, WIFI and including TD-SCDMA, CDMA2000, 3G communication technologies including WCDMA also have their disadvantages: First, these communication methods rely on pre-set network acces...
