Embodiment Construction

[0035] Figure 1a A system for carrying out an embodiment of the method according to the invention is shown in a schematic diagram. The system comprises a vehicle 2 with a peripheral device 8 formed as a control device of the vehicle 2 and a central device 4 formed as a mobile phone, the peripheral device and the central device each comprising a BLE-module and according to the Bluetooth Low Energy (BLE) standard pair. Vehicle 2 also includes an antenna 6 in the form of a roof antenna, a functional system 10 which symbolically represents one or more convenience and / or safety systems, and a bus system 9 . Peripherals 8 , functional systems 10 and antenna 6 are connected to bus system 9 . Alternatively, the antenna 6 can also be designed as a peripheral device in the form of a digital roof antenna (DDA).

[0036] An application program 16 , 18 for controlling the data transmission is installed in each case in the peripheral device 8 and in the central device 4 . The applicatio...

Abstract

The invention relates to a method for transferring data, in which a peripheral device (8) and a central device (4) are wirelessly connected in accordance with the Bluetooth Low Energy (BLE) standard and a data packet (12) is transferred within a transfer window of a Bluetooth Low Energy data channel between the peripheral device (8) and the central device (4).

Description

technical field [0001] The present invention relates to a method for transmitting data, wherein a peripheral device and a central device are wirelessly paired / joined according to the Bluetooth Low Energy standard, and a data packet is transferred between the peripheral device and the central device within a connection event of a Bluetooth Low Energy (BLE) data channel between transfers. Background technique [0002] As a rule, modern vehicles comprise a bus system and a plurality of functional systems, such as eg safety systems and convenience systems, which are connected to the bus system. Furthermore, the vehicle includes at least one control device for controlling the functional systems, which has an application program corresponding to the functional systems and is likewise connected to the bus system. [0003] Furthermore, modern vehicles can include a communication device connected to the bus system for wireless data transmission, ie for data transmission by means of ...
