Method and device for transmitting/receiving data between wireless terminal and electronic pen

A wireless terminal device for transmitting/receiving data to/from an electronic pen, the wireless terminal device comprising:

• a sensor configured to detect an approach and a key input signal of the electronic pen;
• an input device configured to detect and output a touch input, a touch and drag or a key input of a user, or hovering or a hovering movement of the electronic pen;
• a transceiver configured to transmit/receive data to/from the electronic pen in a frequency band;
• a memory configured to store data;
• a display configured to display:
• an icon for each of a transmission mode of the wireless terminal device and a reception mode of the wireless terminal device, and
• a state of the wireless terminal device, wherein the display is further configured to display at least one of:
• data or a transmission data list which is to be transmitted to the electronic pen, or
• data or a reception data list which is to be received from the electronic pen;
• and
• at least one processor configured to:
• receive a key input signal of the electronic pen indicating a selection of the icon for the transmission mode or the icon for the reception mode, and
• in response to a determination by the wireless terminal device that the transmission mode has been selected by the button press input:
• read a transmission list, which is to be transmitted, from the memory when data transmission to the electronic pen is requested after an approach of the electronic pen is detected by the sensor,
• control the display to display the transmission list,
• configure data selected from displayed data in the transmission list as transmission data when a selection request signal is detected, and
• control the transceiver to transmit the configured transmission data to the electronic pen when transmission of the configured transmission data is requested, the configured transmission data being transmitted when it is detected that the electronic pen is moved away from the wireless terminal device in the vertical direction,
• in response to a determination by the wireless terminal that the reception mode has been selected by the button press input:
• control the transceiver to request reception list data stored in the electronic pen,
• control the transceiver to receive a selection of a reception list from a plurality of reception lists stored on the electronic pen, the plurality of reception lists displayed for selection by a user, and
• control the display to display the reception list data when the reception list data is received from the electronic pen,
• wherein preview data of data stored in the electronic pen is received and displayed on the wireless terminal prior to receiving the reception list data from the electronic pen.
