Master-slave system for communication via a Bluetooth low-energy connection

摘要

A master-slave system for communication via a Bluetooth low-energy connection is proposed. The master-slave system has at least one slave device and at least one master device, wherein the slave device and the master device are configured to communicate via the Bluetooth low-energy connection. The slave device has a communication unit and a processing unit, wherein the processing unit of the slave device is adapted to generate a first request message with a header field and a payload field, wherein the processing unit of the slave device is further adapted to a first identity information based on a first stored key and to store as first information in the header field, and wherein the communication unit of the slave device is adapted to send the generated first request message to the master device via the Bluetooth low-energy connection. The processing unit of the slave device is configured to generate at least one second identity information different from the first identity information based on at least one second stored key and to store at least a portion of the at least one second identity information as at least second information in the payload field of the first request message.
