Wireless obtaining method for external data, electronic apparatus and application program

An electronic apparatus established a Bluetooth connection with an external device for requesting a necessary data from the external device, the electronic apparatus comprising:

• a microprocessor component;
• a non-contact data obtaining component electronically connected to the microprocessor component, and reading an external message in non-physical contact manner;
• a Bluetooth transmitting component electrically connected to the microprocessor component;
• wherein, the microprocessor component obtains a MAC address and a model code of the external device through the external message, and activates the Bluetooth transmitting component to open to establish the Bluetooth connection with the external device automatically via the MAC address, and determines the type of the external device via the model code, so as to request the necessary data from the external device through a corresponding communicating protocol in accordance with the type of the external device.

An application program being stored in an electronic apparatus, and executing program code for the electronic apparatus, once the electronic apparatus loading and executing the application program, the electronic apparatus being able to proceed a wireless obtaining method for obtaining data from an external device wirelessly, and the wireless obtaining method comprising:

• a) reading an external message in non-physical contact manner;
• b) retrieving a MAC Address of the external device from the external message;
• c) proceeding automatically with Bluetooth pairing with the external device and establishing Bluetooth connection via the MAC Address;
• d) retrieving a model code of the external device from the external message;
• e) determining the type of the external device according to the model code;
• f) activating a corresponding communication protocol according to the type of the external device for communicating with the external device;
• g) requesting for a necessary data from the external device;
• h) opening a data record sheet in accordance to the type of the external device;
• and
• i) filling in the necessary data obtained from the external device into a corresponding data field in the opened data record sheet.
