BLUETOOTH MODULE OF VEHICULAR NAVIGATION DEVICE

摘要

The present invention relates to a Bluetooth module of a vehicular navigation device, in which the vehicular navigation device mounted to a vehicle is equipped with a Bluetooth module, and stably transmits a beacon signal to an outside of the vehicle, thereby providing a beacon service, such as identification/authentication or membership service, in a designated area. The vehicular navigation device includes a body mounted to a vehicle, and a power supply supplied by a power from the vehicle. The Bluetooth module includes a beacon transmitting unit for transmitting a beacon signal having a designated code value in a signal intensity which is controlled to reach a designated distance outside the vehicle, by at least one of the power supplied from the vehicle and the power charged in the power charger, a pairing processing unit for pairing with the designated terminal at short distance by any one of the vehicle power and the charged power, a Bluetooth communication unit for communicating with the paired terminal at short distance, and a communication processing unit for communicating the terminal to control transmission of the beacon signal, based on the communication.
