Detailed Description
The WiFi Bluetooth communication system in the wireless local area network and Bluetooth complementary communication method is shown in figure 1 and comprises an equipment discovery module, an equipment connection module and a data communication module; the device discovery module sets communication priority and scans WiFi and Bluetooth device information in the environment; the equipment connection module is used for completing the connection with the specified equipment according to the communication priority rule; and the data communication module is used for finishing the sending of the communication data according to the communication priority rule. The complementary discovery, complementary connection, and complementary communication of the lan and bluetooth complementary communication systems are described below, respectively.
Example (b):
the device discovery module sets the priority of communication, scans WiFi and Bluetooth devices in the environment, stores the device discovery result in a communication list, and acquires device information corresponding to the communication mode. As shown in fig. 2, when a device a to be connected is found at a high priority or a second priority, whether the device a exists in the device list is queried, if the device a exists in the device list, it indicates that the device information of the communication method of the device a already exists in the device list, and the device information corresponding to the communication method of the device a to be connected, which is currently found, is used to update the corresponding device information in the device list; if the device A does not exist in the device list, the fact that the device information of the communication mode of the device A does not exist in the device list is indicated, and the device A and the device information of the corresponding communication mode are stored in the device information list; after the above procedure, whether the device information of the device a in the device list is changed relative to the device information of the original device a in the device list is checked, if not, the other devices are continuously scanned, and if the device information of the device a in the device information list is changed, the device information of the device a and the device a is returned to the application program, and then the other devices are continuously scanned.
After the steps, the problem that the equipment cannot be discovered by other equipment due to the abnormity or the function shutdown of one short-distance communication module configured by the equipment is prevented as much as possible.
The connection process with the designated device is as follows: and the user selects the equipment B needing to be connected, at this time, the communication mode equipment information of at least one equipment B is required to be ensured to exist in the equipment information list, otherwise, the previous step is required to be returned to scan the equipment in the environment until the equipment B and the communication mode equipment information of at least one equipment B are stored in the equipment information list.
As shown in fig. 3, it is determined whether the device list has the high-priority communication mode device information of the device B, if the device information list has the high-priority communication mode device information of the device B, a wireless connection is established with the device B, then it is queried whether the device information list has the device information of the second priority communication mode of the device B, and if the device information list has the device information of the second priority communication mode of the device B, a wireless connection is established with the device B in the second priority communication mode; if the device information list does not contain the device information of the high-priority communication mode of the device B, the device information of the second-priority communication mode of the device B certainly exists, and the device B directly establishes the wireless connection of the second priority. So far, the connection mode of the device B has three possibilities, i.e. the device B establishes a wireless connection in a high-priority communication mode; the device B establishes wireless connection of a communication mode of a second priority, and the device B simultaneously establishes wireless connection of two communication modes, at the moment, the specific connection condition of the communication mode of the device B needs to be inquired, whether the device B establishes wireless connection with the communication modes of the high priority and the second priority is judged, if the wireless connection is established by the high priority and the second priority, the communication connection of the device B is finished, if one of the communication modes of the high priority and the second priority is not connected, the device B is requested for device information, and after the wireless connection of all the communication modes is tried to be established, the connection process of the communication mode B is finished. Even if some short-distance communication connection in the two devices is abnormally disconnected, or some short-distance communication module at any end is abnormal or the function is closed, the transmission of the application program shared information or the control information cannot be influenced.
The data communication module performs data communication with a designated device according to a communication priority rule, as shown in fig. 4, first judges whether a high priority communication mode is connected, if the high priority communication mode is connected with a device S designated to be communicated, transmits data through the high priority communication mode, if the high priority communication mode is not connected with the device S, judges whether a sub priority communication mode is connected, if the sub priority communication mode is connected with the device S, transmits data through the sub priority communication mode, if the sub priority communication mode is not connected with the device S, judges whether device information of the device exists in a device list of all communication modes, if so, tries to perform device connection according to the device information connected last time and prompts a user that the device is being connected, if the device information of the device S does not exist in the device list of all communication modes, prompting the user that the device is not connected.
When the communication modes with the high priority and the communication modes with the second priority are connected with the equipment S to be communicated, the data communication module automatically selects the communication mode with the high priority for data communication, and if the connection of the communication mode with the high priority is accidentally disconnected, the data communication module automatically selects the communication mode with the low priority for communication with the equipment S.
If one of the two communication modes, namely the WiFi communication mode and the Bluetooth communication mode, is set as a high-priority communication mode, the other communication mode is a suboptimal communication mode.
The WiFi device information in the device information described in the present invention includes but is not limited to a wireless local area network MAC address, a wireless local area network IP address, and a wireless local area network device name, and the bluetooth device information includes but is not limited to a bluetooth MAC address and a bluetooth device name.
