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

摘要

A wireless method for obtaining external data is comprised of an electronic apparatus, an external message and an external apparatus. The electronic apparatus reads an external message without physical contact and identifies a Media Access Control (MAC) Address of an external apparatus in accordance with the contactless message. The electronic apparatus establishes a wireless connection with the external apparatus directly using the identified MAC Address, and obtains necessary data from the external apparatus through the wireless connection. Therefore this wireless method circumvents the hassle for user to turn on and off a Bluetooth transmitting component of the electronic apparatus, select a connecting target, and establish the wireless connection with the external apparatus manually all together.
