Embodiment Construction

[0031] Embodiments of the present invention will be described below with reference to the relevant drawings. In the drawings, the same reference numbers refer to the same or similar elements or method flows.

[0032] figure 1 It is a simplified functional block diagram of the Bluetooth communication system 100 according to an embodiment of the present invention. The Bluetooth communication system 100 includes a Bluetooth master device 110 and a Bluetooth device group 102, wherein the Bluetooth device group 102 may include a plurality of member devices.

[0033] In practical applications, a plurality of member devices in the Bluetooth device group 102 can establish a Bluetooth piconet in various ways compliant with the Bluetooth communication standards, and can perform various commands or commands through the Bluetooth piconet. data transmission. Alternatively, multiple member devices in the Bluetooth device group 102 may collectively form a coordinate set that conforms to t...

Abstract

The invention relates to a Bluetooth communication system and a related Bluetooth device group. The Bluetooth communication system comprises: a Bluetooth master control device; and a Bluetooth device group including a first member device and a second member device. The first member device may generate a first group identification code corresponding to the first member device, and generate and transmit a target Bluetooth packet including the first group identification code to the Bluetooth master device. The second member device can generate a second group identification code corresponding to the second member device according to the device group identification information. The Bluetooth master device can identify the first member device as a first privileged device according to the position of the first group identification code, can transmit a first privileged pairing notification to the first member device, and can generate a first secret key. The first member device may generate a second key corresponding to the first key upon receiving the first privileged pairing notification.

Description

technical field [0001] The present invention relates to bluetooth technology, in particular to a bluetooth communication system which can improve the generation efficiency of keys required for data transmission between bluetooth master control device and bluetooth equipment group, and related bluetooth equipment group. Background technique [0002] The Bluetooth technology is divided into two categories, one is the Classic Bluetooth / LegacyBluetooth technology, and the other is the Bluetooth Low Energy (BLE) technology. BLE technology and Bluetooth legacy technology are not compatible (or not completely compatible) with each other, but the two technologies can coexist on the same Bluetooth device or the same Bluetooth chip. In other words, a single Bluetooth device or a single Bluetooth chip can be designed to support both the BLE technology and the Bluetooth legacy technology, or it can be designed to support only one of the Bluetooth communication standards. The new low-po...
