Apparatus and method for data transmission using bluetooth signal strength in portable communication system

A method for transmitting data through an Object Push Profile (OPP) service in a portable terminal, comprising the steps of:

• displaying a list of transmittable data items and detecting whether one or more data items to be transmitted are selected when a data transmission event is generated;
• searching neighboring Bluetooth devices and measuring signal strength levels of Bluetooth signals of the searched Bluetooth devices when detecting that one or more of the data items to be transmitted are selected;
• displaying a list of the searched Bluetooth devices and selecting one or more Bluetooth devices to receive the selected data items;
• and
• transmitting the selected data items to the selected Bluetooth devices.
