Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] After the Bluetooth device is turned on, it will broadcast data packets (also known as Bluetooth signals) to the surroundings. If there is a host (other Bluetooth devices) in the detection state in the surrounding environment, it will receive the data packets and then analyze the data packets. In this way, the broadcasting bluetooth device is identified, and then it is judged whether to request to establish a connection for data transmission and other subsequent steps.

[0032] According to an embodiment of the present invention, a broadcasting method of a Bluetooth device is provided, which is used for broadcasting data packets to the surrounding environment when the Bluetooth device is turned on and still in a standby state, such as figure 2 Shown is a flow chart of the broadcasting method of the Bluetooth device according to the present invention, the broa...

Abstract

The invention discloses Bluetooth equipment and a broadcasting method therefor. The method comprises the steps: setting a corresponding relation between different time duration when a request from another piece of Bluetooth equipment is not received after the Bluetooth equipment starts to broadcast a data package and different broadcasting schemes of a data package of the Bluetooth equipment in advance; recording the time duration when the request is not received after the Bluetooth equipment starts to broadcast the data package; and carrying out corresponding adjustment of the broadcasting schemes of the data package of the Bluetooth equipment based on the preset corresponding relation according to the recorded time duration. According to the technical scheme of the invention, the corresponding adjustment of the broadcasting schemes of the data package of the Bluetooth equipment based on the preset corresponding relation according to the recorded time duration can be carried out, so as to adapt to different conditions and to reduce the energy consumption of the Bluetooth equipment.

Description

technical field [0001] The invention relates to the communication field, in particular to a bluetooth device and a broadcasting method thereof. Background technique [0002] For a bluetooth device (also called a broadcaster device) as a portable device in the prior art, the action between it and the host (another bluetooth device, also called a scanner device) when it is in a standby state can be described as follows : The bluetooth device continuously broadcasts data packets (bluetooth signals) to the outside world so that other bluetooth devices can search for them. The host enters the listening state when searching for bluetooth devices, and displays the information of the found bluetooth devices on the interface after receiving the broadcast packets. If the host intends to continue to connect with the Bluetooth device, it sends a SCAN_REQ packet (scanning request, a scan request packet sent by the host to request more information about the Bluetooth device) to the Blueto...
