1. A method in a wireless communication system supporting Bluetooth communication, the method comprising:
performing, by an In Flight Entertainment (IFE) device, a scan for a first Bluetooth low energy (BLE) device and a first Bluetooth basic rate/enhanced data rate (BR/EDR) device,
wherein the scan for the first BLE device and the first Bluetooth BR/EDR device is performed in a time division (TD) method performed in different time intervals,
wherein the scan for the first BLE device includes a step of receiving a first advertisement signal of the first BLE device,
wherein the scan for the first Bluetooth BR/EDR device includes a step of transmitting, by the IFE device, a scan signal; and receiving, by the IFE device, a first scan response signal from the first Bluetooth BR/EDR device;
receiving, by the IFE device, a second advertisement signal from a second BLE device;
sorting, by the IFE device, a list of the first and second BLE devices based on received signal strength indication (RSSI) values of the first and second advertisement signals; and
performing, by the IFE device, a connection with the first BLE device or the first Bluetooth BR/EDR device.
