Problems solved by technology

Although this method solves the problem of the Bluetooth main receiving device forwarding source data, usually some inter-device information needs to be transmitted between the Bluetooth main receiving device and the Bluetooth secondary receiving device, such as data receiving and receiving status, packet loss, volume setting instructions, switch Machine instructions, etc., and in this scheme, because the frequency hopping sequence of the Bluetooth secondary receiving device and the Bluetooth clock are completely synchronized with the Bluetooth primary receiving device and the data source device, there is no independent clock and frequency modulation between the Bluetooth primary receiving device and the Bluetooth secondary receiving device sequence, so independent data transfer between the two is not possible
This limits the development of this monitoring mode, and it is for this reason that most Bluetooth headsets on the market use the aforementioned scheme of forwarding data by the Bluetooth master receiving device through custom Bluetooth or other protocols to solve the problem in this monitoring mode. The problem of data transmission is of great significance to the promotion and application of the program

Embodiment 1

[0035] This embodiment discloses a Bluetooth system. The system includes a Bluetooth primary receiving device and a Bluetooth secondary receiving device. The system needs to form a Bluetooth network together with a source data device. In this Bluetooth network, the Bluetooth primary receiving device is a Bluetooth The master device and the source data device are all Bluetooth slave devices. The Bluetooth secondary receiving device is a listening device. The Bluetooth secondary receiving device has been configured as a listening state, which synchronizes some Bluetooth link parameters of the Bluetooth master receiving device, including Bluetooth clock, Bluetooth master. The Bluetooth address of the device and the Bluetooth slave device, the 3BIT logical address of the slave device, the frequency hopping sequence, the connection key, the encoding key and other low-level Bluetooth protocol parameters and the upper-layer Bluetooth protocol parameters such as L2CAP, RFCOMM, Handfree,...

Embodiment 2

[0060] The Bluetooth system in this embodiment includes a Bluetooth primary receiving device and a Bluetooth secondary receiving device, and the system needs to form a Bluetooth network together with the source data device.

[0061] The difference from the first embodiment is that in this Bluetooth network, the source data device is a Bluetooth master device, the Bluetooth master receiving device is a Bluetooth slave device, the Bluetooth secondary receiving device is a listening device, and the Bluetooth secondary receiving device has been configured to be in a listening state. It synchronizes some bluetooth link parameters of the bluetooth master receiving device, including bluetooth clock, bluetooth address of bluetooth master and bluetooth slave, 3BIT logical address of slave, frequency hopping sequence, connection key, encoding key and other underlying bluetooth Protocol parameters and upper-layer Bluetooth protocol parameters such as L2CAP, RFCOMM, Handfree, A2DP, etc. I...

Abstract

The invention relates to the technical field of bluetooth communication, and specifically discloses a bluetooth system, a bluetooth device and a bluetooth scheduling method. The bluetooth scheduling method comprises: a bluetooth master receiving device executes a bluetooth master receiving time slot in a receiving time slot of a source data device, which enables the source data device to follow A data sending operation that does not send data within N time slots; in the sending time slot of the source data device, the Bluetooth primary receiving device sends inter-device data to the Bluetooth secondary receiving device, and the Bluetooth secondary receiving device receives the inter-device data sent by the Bluetooth primary receiving device. ; In the receiving time slot of the source data device, the Bluetooth secondary receiving device sends inter-device data to the Bluetooth primary receiving device, and the Bluetooth primary receiving device receives the inter-device data sent by the Bluetooth secondary receiving device. The bluetooth device, the bluetooth system and the bluetooth scheduling method provided by the present invention can realize data transmission between the bluetooth primary receiving device and the bluetooth secondary receiving device when the bluetooth secondary receiving device is in the monitoring mode.

Description

technical field [0001] The invention relates to the technical field of Bluetooth communication, in particular to a Bluetooth device, a system and a scheduling method. Background technique [0002] Bluetooth is a wireless technology standard that can realize short-distance data exchange between fixed devices, mobile devices and building personal area networks. A Bluetooth link includes a Bluetooth master device (Master) and a Bluetooth slave device (Slave). Bluetooth The network is clocked by the bluetooth master device and uses frequency hopping communication at a frequency of 1600 hops per second. The definition of the Bluetooth specification includes the concept of a time slot (Slot), a time slot is 1 / 1600 second, that is, 625us, and the Bluetooth time slot includes the master-slave time slot that alternates in turn (Master-to-Slave time slot) And the slave-to-master time slot (Slave-to-Master time slot), in the master-slave time slot, the Bluetooth master device sends da...
