Abstract: Embodiments of the present disclosure disclose a method and a device for monitoring a door lock state. The method specifically comprises searching for a door lock service provided by a server according to a door lock service identification code that is broadcasted by the server and in a corresponding relation to the door lock service, establishing a Bluetooth connection corresponding to the door lock service with the server, and reading a door lock state record characteristic value corresponding to the door lock service by means of the Bluetooth connection according to the door lock service identification code, wherein the door lock state record characteristic value corresponding to the door lock service comprises open or closed. According to the method and the device for monitoring the door lock state, the real-time state of a door lock can be checked by means of a mobile terminal.

Abstract: An embodiment of the present disclosure discloses a method, an apparatus and a system for adjusting vehicle information, wherein the method comprises: discovering, by a mobile end, various service information supported by a vehicle end and characteristics corresponding to the various service information by scanning Universally Unique Identifiers (UUIDs) broadcast by the vehicle end; receiving from the vehicle end and storing, by the mobile end, the characteristics with vehicle information which is an indication of the characteristics; and if the mobile end's established connection with the vehicle end changes, sending, by the changed mobile end pre-saved vehicle information to the vehicle end, so that the vehicle end adjusts current vehicle information according to the received vehicle information. The embodiments of the present disclosure free users from adjusting vehicle information manually, reduces preparation work before driving a vehicle and saves time and energy.

Abstract: The embodiment of the present disclosure discloses a method and device for controlling a car light switch through Bluetooth technology. The method comprises the following steps of receiving a UUID broadcast by the car lights by a mobile terminal; configuring light control services corresponding to the car lights, characteristics of the light control services, and configuration descriptors of the characteristics and establishing Bluetooth connection with the car lights according to the UUID; amending the configuration descriptors of the characteristics on the car through a Bluetooth connection to switch on or off the car lights. By the method and the device, Bluetooth connection among the mobile terminal and the car lights is established to amend the configuration descriptors of the characteristics so as to switch on or off the car lights, and thus the car lights are remotely switched on or off to provide illumination for the users.
