Abstract
A method and a system for generating and transmitting a BLE advertising packet through Classic Bluetooth are provided. By modifying the modulation characteristics and packet generation characteristics of Classic Bluetooth, the BLE advertising packet is carried by a Classic Bluetooth packet, the minimum frequency deviation for Classic Bluetooth is modified, and transmission phases of the Access Code and the Header in the Classic Bluetooth packet are skipped when transmitting the Classic Bluetooth packet, such that the BLE advertising packet can be transmitted through Classic Bluetooth, thereby implementing a Bluetooth beacon function.
Claims13
A method for generating and transmitting a Bluetooth Low Energy (BLE) advertising packet through Classic Bluetooth, comprising steps of:
- step S1011, generating a BLE advertising packet based on data to be broadcasted, wherein the BLE advertising packet comprises Preamble, Access Address, PDU and CRC, and the CRC is calculated based on content of the PDU;
- step S1012, selecting, according to a length of the BLE advertising packet, an applicable Classic Bluetooth packet type;
- and step S1013, generating a Classic Bluetooth packet of the selected Classic Bluetooth packet type, wherein the Classic Bluetooth packet comprises Access Code, Header and Payload, the Access Code and the Header are generated by a Classic Bluetooth baseband unit, and the BLE advertising packet is carried by the Payload.
A system comprising a Classic Bluetooth transmitter, wherein the Classic Bluetooth transmitter is configured to
- generate a BLE advertising packet based on data to be broadcasted, wherein the BLE advertising packet comprises Preamble, Access Address, PDU and CRC, and the CRC is calculated based on content of the PDU;
- select, according to a length of the BLE advertising packet, an applicable Classic Bluetooth packet type;
- and
- generate a Classic Bluetooth packet of the selected Classic Bluetooth packet type, wherein the Classic Bluetooth packet comprises Access Code, Header and Payload, the Access Code and the Header are generated by a Classic Bluetooth baseband unit, and the BLE advertising packet is carried by the Payload.
