Bluetooth Scatternet scheduling method

Abstract

The invention discloses a Bluetooth Scatternet scheduling method. The Bluetooth Scatternet scheduling method comprises the steps of, after setting a profile scene in each Piconet where a Bluetooth device joins in, setting the priority of the profile scene of each Piconet where the Bluetooth device joins in and setting that the priority of a course initiated by a Bluetooth device processing user isat least higher than the priority of the profile scene in one Piconet where the Bluetooth device joins in; when the course initiated by the user is received, judging whether the priority of the profile scene in the next Piconet where the Bluetooth device joins in is higher than the priority of processing the course initiated by a user every time switching the Piconet for profile scene; if the priority of processing the course initiated by the user is higher, processing the course initiated by the user; otherwise, switching to the next Piconet for profile scene. Therefore, the Bluetooth Scatternet scheduling method can increase pairing and connection efficiency of Bluetooth devices between piconets in the scatternet, and accordingly can improve the user satisfaction.

Description

technical field [0001] The invention relates to the technical field of bluetooth communication, in particular to a bluetooth Scatternet scheduling method. Background technique [0002] At present, Piconet (piconet) refers to a micro-network composed of Bluetooth devices in a small range using Bluetooth technology. At the same time, multiple Piconets can also be interconnected to form a Scatternet (Scatternet). The establishment of the piconet is based on a bluetooth device as a master device to connect multiple other bluetooth devices as slave devices, and consists of up to 8 bluetooth devices. In a piconet, only one pair of bluetooth devices are working at the same time. If other bluetooths have inquiry, page, inquiry scan or page scan processes at this time, these processes will be completed in the work of several bluetooth devices in the previous piconet. only after. [0003] Moreover, in a piconet, two bluetooth devices are using a certain bluetooth profile to work, s...

Problems solved by technology

[0003] Moreover, in a piconet, two bluetooth devices are using a certain bluetooth profile to work, since a bluetooth device can be not only a master device, but also a slave device, so when a bluetooth device as a master device in a piconet At the same time, when the Bluetooth device is used as a slave device in another piconet, if the inquiry, page, inquiry scan or page scan process is initiated in the piconet where the Bluetooth device is the master device, the traditional Scatternet scheduling method It will wait for the work of all the Bluetooth devices in the running piconet to complete, and then switch to these processes for processing

If the number of piconets is large, the waiting time will be longer, resulting in poor user experience and making users feel that the process of pairing and connecting Bluetooth devices is inefficient
