Description

Bluetooth communication method, electronic equipment, readable storage medium and chip Technical Field The present application relates to the field of bluetooth communication technologies, and in particular, to a bluetooth communication method, an electronic device, a readable storage medium, and a chip. Background Currently, bluetooth low energy (bluetooth low energy, BLE) devices (scanning devices) typically discover other bluetooth devices (broadcasting devices) around in an active scanning manner. For example, the bluetooth low energy device actively initiates a Scan Request (Scan Request) after receiving a broadcast packet message sent by other surrounding devices, and waits for a surrounding bluetooth device Response (Scan Response). The surrounding bluetooth devices may reply to the response message after receiving the scan request. After collecting the response messages, the bluetooth low energy device can decide whether to perform further interaction with the bluetooth device, such as connection establishment, etc. By the method, other surrounding Bluetooth devices can be found more quickly, but the active scanning process can obviously increase the power consumption of the device and influence the use experience of a user. Disclosure of Invention The application provides a Bluetooth communication method, electronic equipment, a readable storage medium and a chip, which solve the problems that in the prior art, equipment power consumption is increased and the use experience of a user is affected in the process of finding other surrounding Bluetooth equipment through active scanning. In order to achieve the above purpose, the application adopts the following technical scheme: In a first aspect, a bluetooth communication method is provided, applied to an electronic device, where the electronic device supports bluetooth communication with a low power consumption radio frequency and a main radio frequency, and the method includes adopting a passive scanning mode to receive a first BLE broadcast packet, where the electronic device operates in the low power consumption radio frequency, and switching from the passive scanning mode to the active scanning mode when the first BLE broadcast packet meets a first preset condition, and operating in the main radio frequency. According to the method provided by the embodiment of the application, the electronic equipment switches the scanning mode under the condition that the first BLE broadcast packet meets the first preset condition, so that the electronic equipment can switch the scanning mode according to the need, and works in a low-power-consumption radio frequency state under the passive scanning mode, and works in a main radio frequency state under the active scanning mode, and the balance between the power consumption and the function of the equipment can be realized on the premise of playing the low-power-consumption advantage of the low-power-consumption radio frequency. In some embodiments, the first preset condition comprises at least one of a first BLE broadcast packet being of a specified type, the first BLE broadcast packet carrying indication information indicating that the scanning device receives a second BLE broadcast packet, the data information carried by the first BLE broadcast packet lacking target information required for executing a service, the data information carried by the first BLE broadcast packet comprising information of the specified data format and the data type, and the service corresponding to the data information carried by the first BLE broadcast packet being of the specified service type. Optionally, the first preset condition may be that the first BLE broadcast packet is of a specified type, and the data information carried by the first BLE broadcast packet satisfies that the data information includes indication information indicating that the scanning device receives the second BLE broadcast packet, and/or that the data information lacks target information required for executing the service, and/or that the data information includes information of a specified data format and a specified data type, and/or that the service corresponding to the data information is of a specified service type. In this embodiment, whether the electronic device needs to switch the scan mode is indicated by limiting the type of the BLE broadcast packet and/or the content of the carried data information, so that the electronic device can switch as required, and frequent switching is avoided from affecting the communication effect. In some embodiments, the specified types include adv_ind and adv_scan_ind. In one implementation, the electronic device may determine the type of the first BLE broadcast packet from a broadcast data field in a broadcast data type field in a data structure of the first BLE broadcast packet. In some embodiments, when the first BLE broadcast packet meets a first preset condition, the passive scanning mode is switched to the
