Abstract

The invention relates to a bluetooth connection setup method and a bluetooth device. A method for receiving and outputting radio signals to set up a bluetooth connection which includes receiving, within a predetermined period (11), at least two of the advertising data packets (13a,13b) which originate from a device (3); determining starting times (t1a,t1b) of the two advertising data packets (13a,13b); and outputting, after the predetermine period (11), of the device's own advertising data packets (22a,22b), at the device's own starting times (txa,txb) which are selected so that the device's own advertising data packets (22a,22b) do not chronologically overlap with advertising data packets (13c,13d,15c,15d,17f,17g) which are output by the device (3,5,7) after the predetermined period.

Description

technical field [0001] The invention relates to a method for receiving and sending radio signals to establish a Bluetooth connection, and a Bluetooth device designed to carry out the method. Background technique [0002] EP 2 672 764 A1 discloses a method and a device for interrupting short-range wireless communication, wherein the power level of a wireless communication message is measured, and wherein the communication connection is interrupted if the power level is above a threshold value. To avoid repeated collisions between devices waking up at the same time on the same channel, one device will wait for a reliable amount of time. [0003] US 9185745 B2 discloses a signaling mechanism for wireless networks, wherein a first network is assigned a first time window and a second network is assigned a second time window, wherein the networks operate at different powers. [0004] US 2015 / 0223169 A1 discloses a method for initial indication of block allocation for wireless net...
