Description
Technical Field
The present invention relates to bluetooth communication technologies, and in particular, to a bluetooth multi-pairing connection method and medium.
Background
The applications of bluetooth electronic products are more and more diversified. For example, a bluetooth headset has a requirement for connecting 2 or even more than 2 mobile phones; a pair of TWS headphones is connected to both the opposing ear and the handset. Thereby, the problem of multiple connections is derived.
If the multi-connection is not well designed, the connection speed is slow and the user experience is poor. The multi-connection technology of the bluetooth products in the market often adopts the time-sharing multiplexing technology, for example, the first designated device is connected in the period of time, the second designated device is connected in the next period of time, and so on. This method is often inefficient and slow in bluetooth bandwidth utilization, and sometimes cannot be connected for more than 10 seconds.
Referring to fig. 4, in the standard bluetooth core protocol, both connected devices are specified, and one device performs a page action and the other device performs a page scan action using the same bluetooth address. FIG. 4 is a schematic representation of a Page/Page scan. With further reference to FIG. 5, Page behavior features: the period is 1.25ms, and the slot is divided into tx slot and rx slot which are each 625 us. In a tx slot of 625us, two ID packets with different frequency points but same content are sent out. Then receives the page scan device's response at the next rx slot. The frequency hopping rate of the page device is 3600hop/s, namely hopping is carried out once every 312.5 microseconds, and 16 frequency points are hopped in 10 milliseconds. Page scan behavior characteristics: typically a relatively large rx window, frequency hopping is once every 1,28 seconds. In order to enable the page equipment to be paired quickly, the Bluetooth core protocol suggests that the window of the page equipment is at least larger than 16 page frequency points, namely more than 10 milliseconds. During the actual use, the window that opens when the bluetooth product of each family is done the page scan is different, in order to be better by on the page, all can open a bigger window.
In a popular way, when a page device and a page scan device are paired and connected, the frequency of the page at a time point is the same as that of the page scan. That is, as long as the behavior of the page continues for more than 1.28s, there is a certain chance to hit the page scan device at one frequency point. So to meet such an opportunity, the bluetooth device will usually continue to page for at least 1.28s or more, most surely 2.56s, or even longer.
The above method is acceptable if only one device is connected. But if 2, 3 or even more devices are connected. Then such an approach would present drawbacks. Referring to fig. 6, the bluetooth bandwidth is used in a time-sharing manner, and the device may need to wait for several page intervals when connecting to one time, which is inefficient and slow; referring to fig. 7, in an extreme case, there is a problem that the always-paired connection cannot be transmitted.
