AI Technical Summary

Problems solved by technology

The increase in scheduling cost means that the possibility of scheduling collisions will increase, especially when the Bluetooth master receiving device is in the role of Bluetooth slave device in two Bluetooth links at the same time, or in the role of Bluetooth master device in one Bluetooth link It is especially obvious when it is a Bluetooth slave device role in another Bluetooth link.

Embodiment 1

[0054] This embodiment discloses a bluetooth system, the system includes a bluetooth main receiving device and a bluetooth secondary receiving device, the system needs to form a bluetooth network together with the source data device, wherein:

[0055] The bluetooth master receiving device includes a scheduling module, a first data sending module, a first data receiving module, a connection module, a CTP data packet generation module, a CTP data packet broadcast module, a reply data receiving module, a first channel jump module, a first Command data transceiver module, command data generation module and standard data transceiver module;

[0056] The connection module is used to establish a standard Bluetooth connection with the source data device. The CTP data packet generation module is used to obtain the data of the connection configuration parameters of the connection module and encrypt and compress these data to form a CTP data packet. The CTP data packet broadcast module is...

Embodiment 2

[0123] The difference between this embodiment and Embodiment 1 is that in the Bluetooth network after networking in this embodiment, the source data device is a Bluetooth master device, the Bluetooth master receiver device is a Bluetooth slave device, the Bluetooth secondary receiver device is a monitoring device, and the Bluetooth secondary receiver device is a Bluetooth slave device. The device has been configured in the listening state, which synchronizes some Bluetooth link parameters of the Bluetooth master receiving device, including the Bluetooth clock, the Bluetooth address of the Bluetooth master device and the Bluetooth slave device, the 3BIT logical address of the slave device, the frequency hopping sequence, and the connection key. Low-level Bluetooth protocol parameters such as keys and encoding keys, and upper-layer Bluetooth protocol parameters such as L2CAP, RFCOMM, Handfree, and A2DP. In order to save energy, the Bluetooth secondary receiving device only monito...

Abstract

The invention relates to the technical field of Bluetooth communication, and particularly discloses main Bluetooth receiving equipment, secondary Bluetooth receiving equipment, Bluetooth communicationsystem and a method for transmitting information between the equipment. The method for transmitting information between the equipment comprises the steps of S1000: networking: the main Bluetooth receiving equipment builds a Bluetooth network connection with source data equipment, and the secondary Bluetooth receiving equipment is added into the Bluetooth network in a monitoring manner, and monitors data sent by the source data equipment; and S2000: command transmission: the main Bluetooth receiving equipment and the secondary Bluetooth receiving equipment perform command transmission. According to the method for transmitting information between the equipment, the main Bluetooth receiving equipment, the secondary Bluetooth receiving equipment and the Bluetooth communication system providedby the invention, the secondary Bluetooth receiving equipment can acquire the data output by the source data equipment in a data monitoring working mode, and meanwhile, the command and data communication between the main Bluetooth receiving equipment and the secondary Bluetooth receiving equipment also can be achieved.

Description

technical field [0001] The invention relates to the technical field of bluetooth communication, in particular to a bluetooth device, a method for transmitting information between bluetooth devices and a bluetooth communication system. 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 provided by the bluetooth master device and uses a frequency of 1600 hops per second for frequency hopping communication. The definition of the Bluetooth specification includes the concept of a time slot (Slot). A time slot is 1 / 1600 seconds, which is 625us. The time slots of Bluetooth include master-to-slave time slots (Master-to-Slave time slots) that appear alternately in sequence. And from-master time slot (Slave-to-Master tim...
