  • the device for connecting a Bluetooth device according to the present invention is the fifth embodiment of the device for connecting a Bluetooth device of the present invention.
  • the device for connecting a Bluetooth device according to the present invention further includes:
  • the saving module 40 is configured to record the Bluetooth connection information between the Bluetooth device and the master device in real time after the master device automatically connects the Bluetooth device according to the order, and save the information to the history record, where
  • the Bluetooth connection information includes: a connection time of the Bluetooth connection, a connection duration of the Bluetooth connection, and a connection number of the Bluetooth connection.
  • the saving module 40 records the connection information in real time and saves it. Specifically, when the master device establishes Bluetooth success with a surrounding Bluetooth device, the related connection information is saved to the history record information, specifically, according to the file format of the history record information, for example, the history record information is saved in an XML format. When the file is in the file, the connection information is stored in an XML file format.
  • the Bluetooth connection information includes the connection time of the Bluetooth connection, the connection duration of the Bluetooth connection, and the number of connections of the Bluetooth connection. Specifically, for example, when the device BBB establishes a Bluetooth connection with the master device, the Bluetooth connection information is updated to the history information. When the device BBB establishes a Bluetooth connection with the master device for 5 minutes and then disconnects, the connection time is 15:34. :01 31/152015, the connection duration is 300s, and the number of connections is accumulated in the number of historical connections. If the number of previous connections is 5, the update is 6.
  • connection information of the device BBB in the history information is updated in the bt_device.xml file to:
  • the Bluetooth connection information may further include other information such as the Bluetooth name of the Bluetooth device when the Bluetooth device changes the Bluetooth device name in addition to the above connection information.
  • the master device When the history information is updated according to the latest Bluetooth connection, when the master device performs the Bluetooth connection again, it can sort according to the latest history information, thereby performing automatic connection.
  • the Bluetooth connection information between the Bluetooth device and the main device is recorded in real time and saved in the history information, so that the history information is updated according to the latest Bluetooth connection.
  • the latest history information can be sorted to improve the speed of the automatic Bluetooth connection of the master device.
