Embodiment Construction

[0069] For clarity, the frame grids in Figures 1 to 5 all represent only those time slots in which transmissions are made from the master user to the slave user, i.e. the opposite state (odd time slots) has been represented in each case omit. In addition, the CLK system clock in each slot is illustrated in hexadecimal notation starting from "OX". The reference marks in the figure are: K1 represents the first communication channel and the first connection, K2 represents the second communication channel and the second connection, M represents the master user, S1 represents the first slave user, and S2 represents the second slave user.

[0070] A prerequisite for using the method according to the invention is the presence of the first link, or the SCO link, operating in probing mode or deactivated mode. The second link can then be configured in the same way, ie using a preferred solution described below based on a second link in probing mode, without any restrictions on the vers...

Abstract

The invention relates to a method for data transmission, in particular on the basis of the Bluetooth standard, in which data packets can be interchanged by radio by means of a timeslot method, in which communication channels are set up between a master subscriber and at least one slave subscriber, at least two communication channels are operated with reduced activity in a first operating mode, such that the data interchange takes place periodically during first time slots which are then followed by second time slots during which no data interchange is intended, a first communication channel, which can be operated in the first operating mode, is synchronized to at least one second communication channel which can be operated in the first operating mode. The invention also relates to a data transmission system which operates on the basis of the Bluetooth method, in particular for carrying out the method according to the invention.

Description

technical field [0001] The invention relates to a data transmission method, especially a data transmission method based on the bluetooth standard, and a data transmission system based on the bluetooth method. Background technique [0002] Such a communication system is described, for example, in German patent application DE 101 25 342 A1. [0003] The Bluetooth system is based on a recently developed communication standard and can perform data transmission based on TDD (Time Division Duplex). In this communication system, individual users define a communication network, a so-called piconet network, in which the data to be transmitted are sent over short wireless distances. [0004] A characteristic of the Bluetooth communication system is that not all users communicating with each other have equal priority. A Bluetooth communication system includes one and only one master user, and at least one slave user. The number of active users, ie users involved in the data exchange...
