Such Bluetooth communication has evolved and recently, Bluetooth low energy (BLE) technology (Bluetooth 4.0) has been widely used in smart phones, retail geofencing and mobile payment. This Bluetooth low-power technology has recently attracted attention because it consumes less power than the standard Bluetooth wireless connection.

Meanwhile, if the lifetime of the Bluetooth low-power device having the advertisement signal transmission interval of 1 second is two years, the battery life of the Bluetooth low-power device varies depending on the advertisement signal transmission interval or the scan signal reception interval, If it is increased to seconds, the life of the same battery can be increased to 4 years.

However, since the conventional Bluetooth low-power device can not set various low-power modes in the link layer on the HCI (Host Controller Interface), which is the interface between the link layer of the host part and the controller part, However, since the host unit adjusts the advertisement signal transmission interval by a software method, there is a problem that the power consumption becomes larger than the adjustment by the hardware system.
