[0047] When the first device determines that a Bluetooth connection needs to be established, it will directly establish a Bluetooth connection based on the pre-saved device information. This eliminates the need to first perform the Bluetooth device discovery process and then establish a Bluetooth connection based on the discovered Bluetooth device, thereby reducing the Bluetooth connection establishment latency and improving the Bluetooth connection establishment speed.

[0055] Figure 7 This is a schematic diagram of the structure of a first device according to an exemplary embodiment. Detailed Implementation

[0056] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0057] Bluetooth connections typically need to follow certain specifications; please refer to [link / reference needed]. Figure 1 As shown, the Bluetooth connection establishment process may include:

[0058] A slave device in peripheral mode sends an advertisement (Adv).

[0059] After receiving an Advance from a slave device, the master device in central mode can send a Scan Request to the slave device and receive a Scan Response from the slave device based on the Scan Request, thus completing the device discovery process. This Scan Response can provide slave device information not carried in the Advance.

[0060] After the master device and slave device complete the mutual discovery process, if the master device determines that a Bluetooth connection needs to be established, it will send an Establish link request and transmit the information required for connection establishment with the slave device, thereby completing a connection establishment.

[0061] After the connection is established, the pairing process begins, during which encryption and authentication keys are generated.

[0062] After the pairing process is completed, the bonding process will begin. After the bonding process, the next connection will be able to pair quickly.

[0063] During the actual execution process, the slave device is in broadcast mode, continuously sending broadcast signals to the master device. Each broadcast event is transmitted in three Bluetooth broadcast channels, and each event starts transmission with the smallest channel number.

[0064] The master device initiates a scan request. Only if the master device's radio frequency receiving window matches the broadcast transmission window, and the broadcast radio frequency channel and the mobile phone scanning radio frequency channel are the same channel, can the master device receive the broadcast signal from the slave device.

[0065] If the master device partially sends scan requests across multiple channels using a filtering policy, then the broadcaster slave device needs to send a scan response on the same channel in response to the scan requests.

[0066] The master device receives the scan response from the slave device, obtains the device information of the slave device, and initiates a connection request.

[0067] Typically, when a Bluetooth device obtains information about surrounding devices and broadcast messages, it needs to trigger an active scan to acquire more information about slave devices by scanning the current wireless environment. This process is usually time-consuming, generally taking several seconds, and can even take tens of seconds when there are many devices and significant interference. This cannot meet the needs of scenarios requiring rapid acquisition of surrounding device information.

[0068] like Figure 2 As shown in the embodiments of this disclosure, an information processing method is provided, executed by a first device, the method comprising:

[0069] S110: Determine the Bluetooth connection requirement of the first device; S120: When it is determined that the first device has the Bluetooth connection requirement, establish a Bluetooth connection with the second device according to the device information of the second device that has been saved in advance.

[0070] The first device can be any device that includes a Bluetooth chip. For example, the first device can be a mobile phone, tablet computer, wearable device, smart home device, or smart office device.

[0071] For example, the first device can be a smart speaker, a smart doorbell, or a mobile phone.

[0072] For example, the first device may be a Bluetooth Low Energy (BLE) device; or a BLE / Classic Bluetooth device. A BLE / Classic Bluetooth device is a device that supports both BLE and Classic Bluetooth.

[0073] When the first device determines that it needs a Bluetooth connection, it establishes a Bluetooth connection with the second device based on the pre-saved device information of the second device.

[0074] The second device can be any other Bluetooth device that is listening on the Bluetooth broadcast channel before the first device detects that it has a Bluetooth connection need.

[0075] The first device listens to the Bluetooth broadcast channel to obtain the device information of the second device. If there are Bluetooth devices in peripheral mode near the first device, the device information of the Bluetooth devices will be scanned on the Bluetooth broadcast channel.

[0076] In some embodiments, the first device periodically listens to the Bluetooth broadcast channel to obtain device information of the second device; or it listens to the Bluetooth broadcast channel in real time to obtain device information of the second device.

[0077] For example, before detecting a Bluetooth connection request from the first device, the Bluetooth broadcast channel is scanned in advance to obtain device information, and the device indicated by the device information can be the second device.

[0078] For example, the second device may send an Adv message on the Bluetooth broadcast channel. The Adv message may carry device information of other Bluetooth devices, and the device indicated by the device information may be the second device.

[0079] The device information of the second device may include at least identification information that uniquely identifies the second device. For example, the device information of the second device may also include, but is not limited to, at least one of the following:

[0080] Bluetooth chip identifier;

[0081] Bluetooth address.

[0082] In some embodiments, the device information of the second device may further include:

[0083] Type information indicates the type of Bluetooth chip included in the second device. For example, some Bluetooth chips only support BLE, while others support both BLE and classic Bluetooth.

[0084] In summary, the device information of the second device may include at least the necessary information required for the first device and the second device to establish a Bluetooth connection.

[0085] When the first device determines that a Bluetooth connection needs to be established, it will directly establish a Bluetooth connection based on the pre-saved device information, without having to perform the Bluetooth device discovery process first and then establish a Bluetooth connection based on the discovered Bluetooth device. This reduces the Bluetooth connection establishment latency and improves the Bluetooth connection establishment speed.

[0086] In some embodiments, such as Figure 3 As shown, the method further includes:

[0087] S111: Filter the device information listened to on the Bluetooth broadcast channel according to the broadcast filtering configuration information to obtain the device information of the second device;

[0088] S112: Based on the broadcast configuration information, the device information of the second device is pre-saved in the preset storage space of the first device.

[0089] In this embodiment, the first device listens to the Bluetooth broadcast channel even when there is no Bluetooth connection requirement. That is, it listens to the Bluetooth broadcast channel in advance before detecting a Bluetooth connection requirement and saves the device information of the second device it has pre-listened to. When listening to the Bluetooth broadcast channel, it listens according to the broadcast filtering configuration information.

[0090] This broadcast filtering configuration information can be written into the firmware driver. This configuration information can be used by the first device to select a second device that it might connect to or will connect to from among multiple devices monitored on the Bluetooth broadcast channel. This ensures that the device information saved by the first device is only the device information of the second devices that the first device might connect to via Bluetooth, reducing the amount of device information saved compared to saving information for all devices scanned on the Bluetooth broadcast channel.

[0091] When saving device information of other Bluetooth devices that are being monitored, the first device will save the configuration information based on the broadcast.

[0092] In some embodiments, the broadcast configuration information may include a storage address. This storage address points to storage space for storing pre-scanned device information. This storage space may be a cache space or other storage space.

[0093] In some embodiments, the broadcast save configuration information may also indicate storage capacity. Thus, after the first device initiates Bluetooth device information listening, it does not need to allocate storage space for saving device information in a fixed location in the memory. Instead, when device information for the second device needs to be saved, storage resources can be dynamically allocated temporarily based on the storage capacity indicated by the broadcast save configuration information.

[0094] For example, the pre-saved device information of the second device may include: pre-cached device information of the second device. That is, the device information is stored in a cache space, so that when the first device meets the cleanup conditions, it actively deletes device information that does not need to be continuously stored, reducing the storage space occupied by this device information. If the device information is stored in a cache space, when new Bluetooth device information is detected, the old device information can be directly deleted and the new device information written by replacement or update.

[0095] In some embodiments, if the first device detects that the device information carried by the Adv is insufficient after listening to the device information of the second device, the first device may also send a scan request to the second device on the Bluetooth broadcast channel and receive a scan response returned by the second device based on the scan request. The scan response may carry further device information required by the first device.

[0096] Pre-storing the monitored device information may also include: pre-storing the device information carried in the scan response monitored on the Bluetooth broadcast channel.

[0097] In some embodiments, the broadcast filtering configuration information includes at least one of the following:

[0098] The device information of the alternative device includes at least one of the following: the device type of the alternative device, the device identifier of the alternative device, and the Bluetooth modes supported by the alternative device;

[0099] Used to determine the second device from the candidate devices.

[0100] The filtering parameters can be used to further determine the second device that the first device is most likely to connect to from among the candidate devices.

[0101] In some embodiments, S111 may include:

[0102] Based on the device information of the candidate devices, the device information intercepted on the Bluetooth broadcast channel is filtered to obtain the device information of the candidate devices;

[0103] The second device is determined from the candidate devices based on the service identifier and / or service characteristics included in the filtering parameters.

[0104] For example, the filtering parameters may include one or more device identifier lists; the device identified by one or more device identifiers in the device identifier list is the second device.

[0105] For example, if the first device is a smart home device, for security reasons, the device list identifier corresponding to this filtering parameter can be the device identifier of a device carried or worn by a family member or the device identifier of other Bluetooth devices in the home.

[0106] The device identifier may include: device number and / or device name.

[0107] In some embodiments, the filtering parameters include at least one of the following:

[0108] Business identification (ID) is used to identify the corresponding business;

[0109] Business characteristics are used to describe the attributes of the corresponding business.

[0110] For example, some devices only support audio services, some support video services, some support both audio and video services, and some support projection services.

[0111] The filtering parameters may include a service identifier, which may be determined based on the service that the first device needs to implement via Bluetooth connection.

[0112] In some embodiments, the filtering parameters may not directly define a service identifier, but rather define service characteristics that describe the attributes of the service. For example, these attributes include, but are not limited to, the transmission bandwidth and / or QoS required by the service.

[0113] If a Bluetooth device monitored by the first device can provide resources that provide the business characteristics of the services involved in the first device's business, then such a Bluetooth device can be used as a second device.

[0114] For example, this service characteristic includes, but is not limited to, Quality of Service (QoS), which may impose certain requirements on the bandwidth of the Bluetooth connection and the memory and / or processing resources of the second device. Thus, the first device can select the corresponding second device from the Bluetooth devices it has detected, based on the resource information contained in the device information of the Bluetooth devices it has detected.

[0115] In some embodiments, S112 may include:

[0116] According to the broadcast configuration information, the device information of the second device is pre-stored in a first-in-first-out (FIFO) queue in a preset storage space.

[0117] In this embodiment of the disclosure, a FIFO queue is set in the preset storage space for storing device information. Due to the first-in-first-out characteristic of the FIFO queue, the device information detected later will be added to the FIFO queue, while the device information detected earlier will be discarded from the tail of the FIFO queue.

[0118] In some embodiments, the preset storage space does not have a FIFO queue. The preset storage space records not only the device information of the second device, but also the corresponding record information for each device. This record information can reflect information related to the Bluetooth connection between the first and second devices.

[0119] The record information may include at least one of the following:

[0120] The number of times each device information stored in the storage space is used;

[0121] The number of successful Bluetooth connections between each second device and the first device within a preset time period;

[0122] The duration of a single Bluetooth connection between the first device and each of the second devices.

[0123] At this time, when the first device detects new device information and there is no remaining storage space in the preset storage space, it can prioritize discarding the device information of one or more second devices that have had the fewest Bluetooth connection counts with the first device, as well as the corresponding Bluetooth connection count records, thereby freeing up storage space to store the newly detected device information.

[0124] In some embodiments, the step of pre-saving the device information of the second device in a preset storage space according to the broadcast configuration information includes: according to the broadcast configuration information, when there is no remaining storage space in the preset storage space, updating the monitored device information of the second device in the preset storage space based on the number of times the device information already located in the preset storage space has been used.

[0125] By updating the device information stored in the preset storage space in this way, when new device information of a second device is detected, the device information of the second device that the first device rarely connects to or almost never connects to can be replaced, thereby ensuring that the device information of the second device that the second device frequently connects to is continuously stored in the preset storage space.

[0126] In other embodiments, the method further includes:

[0127] Based on the number of times each second device is used within the current time period, device information whose usage exceeds a threshold is transferred to the bound storage space. This bound storage space stores device information for second devices frequently connected to the first device. Device information in the preset storage space can be discarded according to a first-in, first-out (FIFO) principle when new second device information is detected.

[0128] Thus, in some embodiments, S120 may further include:

[0129] When the first device requires a Bluetooth connection, obtain the location information of the first device;

[0130] If the location information indicates that the first device is in a preset location, the device information is read from the bound storage space first, and a Bluetooth connection is established based on the read device information;

[0131] If the location information indicates that the first device is not in the preset location, the device information is read from the preset storage space first, and a Bluetooth connection is established based on the read device information;

[0132] The preset location can be: a space frequently visited by the first device based on user instructions, such as home, company, or classroom.

[0133] The location information can be determined based on the positioning chip of the first device. The positioning chip can be a satellite positioning chip or a positioning chip that performs positioning based on base station signals or WiFi signals.

[0134] In some embodiments, the detection of a Bluetooth connection requirement includes at least one of the following:

[0135] Bluetooth application detected to be running;

[0136] Bluetooth enable command detected;

[0137] The current time or the current device status of the first device is detected to meet the determination conditions for Bluetooth connection requirements.

[0138] The Bluetooth applications include, but are not limited to: Bluetooth-based file sharing applications.

[0139] For example, a command to enable Bluetooth is detected in the system message bar of an electronic device. This command could be a tap or swipe operation.

[0140] For example, the Bluetooth enable command may also include: a Bluetooth enable command detected in an application interface that has embedded Bluetooth application functionality.

[0141] For example, based on the Bluetooth connection history of the first device, even if the first device does not currently have a Bluetooth application launched or detect a Bluetooth enable command, the current time period is considered to be a high-frequency period for Bluetooth connections.

[0142] In some embodiments, if the first device is set from a peripheral mode to a central mode, then the current state of the first device can be considered to meet the determination condition of having a Bluetooth connection requirement.

[0143] In other embodiments, the first device is configured such that when the battery level is above a certain threshold, the device state of the first device is considered to meet the criteria for having a Bluetooth connection requirement.

[0144] In some embodiments, if the first device activates a preset service at a preset location, the device state of the first device can also be considered to meet the judgment condition for having a Bluetooth connection requirement. For example, if a user's mobile phone is at home and audio playback is enabled, they may have a need to share songs from their phone to a smart speaker for playback. In this case, the device state of the first device is considered to meet the judgment condition for having a Bluetooth connection requirement.

[0145] In some embodiments, the method further includes:

[0146] Predict the first time period during which the first device will have a Bluetooth connection requirement;

[0147] S111 may include:

[0148] Listening to the Bluetooth broadcast channel begins in a second time period earlier than the first time period.

[0149] The first time period during which the prediction of the first device having a Bluetooth connection requirement includes, but is not limited to, at least one of the following:

[0150] The first time period was determined based on the Bluetooth connection records between the first device and other devices;

[0151] The first time period is determined based on the location of the first device. For example, if the first device may be in a private space such as a home or a private car, then any time period after the current moment can be considered the first time period.

[0152] For example, based on the Bluetooth connection history of the first device, although the first device does not currently have a Bluetooth application launched or a Bluetooth enable command detected, the current time period is considered to be a high-frequency Bluetooth connection period. Therefore, the current time period is considered to be a period in which the first device needs to enter the Bluetooth broadcast channel in advance to obtain the device information of the second device. Thus, after predicting the first time period, the first device starts listening to the Bluetooth broadcast channel in the second time period earlier than the first time period to obtain the device information of the second device, thereby reducing unnecessary listening to the Bluetooth broadcast channel.

[0153] In some embodiments, the first time period during which the first device is predicted to have a Bluetooth connection requirement may include:

[0154] If the first device is a preset type of device, then the first time period when the first device has a Bluetooth connection requirement is predicted.

[0155] In some embodiments, S111 may include: if the first device is not a preset type device, by default listening to the Bluetooth broadcast channel when no stop listening command is detected, to obtain the device information of the second device.

[0156] For example, a Bluetooth speaker can be a device other than the preset type of device. Devices other than the preset type include, but are not limited to, smart home devices.

[0157] The preset type of device may be: a device with a Bluetooth chip but with limited use of Bluetooth sharing function. This preset type of device includes, but is not limited to, devices that the user carries or wears. Of course, this is just an example.

[0158] In some embodiments, regardless of whether the first device is a preset type device, it will only listen to the Bluetooth broadcast channel within a selected time range to obtain the device information of the second device. For example, a smart home device may not listen to the Bluetooth broadcast channel to obtain the device information of the second device during nighttime periods such as early morning when family members are not active, and time periods outside of nighttime periods can be considered as the selected time range.

[0159] Of course, the above are just examples of alternative time ranges, and the actual implementation is not limited to the examples above.

[0160] refer to Figure 4 As shown, the main device is a Bluetooth-enabled device and is running an application (APP);

[0161] The firmware program adds configuration filtering and caching interfaces, allowing the app to control these through configuration modifications.

[0162] When the app starts, this function is enabled, and control parameters are sent through process A. At least one of the following conditions must be set:

[0163] Equipment type;

[0164] Equipment manufacturers;

[0165] Filtering parameters;

[0166] Cache size;

[0167] Cache update methods, etc.

[0168] The firmware program loads configurations and sets up the hardware chip. The configurations loaded by the firmware program here include, but are not limited to: broadcast filtering configuration information and broadcast saved configuration information.

[0169] When the master device's Bluetooth chip is monitoring slave devices a, b, and c, it reports the device information of the slave devices that match the broadcast filtering configuration information to the APP. At the same time, the firmware program saves the device information that matches the broadcast filtering configuration information according to the broadcast save configuration information.

[0170] When the app needs the device information of the slave device, it can save the configuration information according to the broadcast and read the corresponding device information from the corresponding storage space.

[0171] This disclosure aims to provide a method for quickly obtaining broadcast information from nearby wireless devices for Bluetooth connection. The method includes two roles: a master device and a slave device. For example, the master device may be a smartphone that supports Bluetooth, and the slave device may be a Bluetooth terminal device to be connected to the smartphone.

[0172] refer to Figure 5 As shown, the method may include the following steps:

[0173] S101: The first device adds Bluetooth chip firmware, and configures broadcast filtering configuration information and broadcast saving configuration information through the firmware.

[0174] Configure the broadcast filter to select the type of Bluetooth device to scan, such as BLE Bluetooth devices or BLE / Classic Bluetooth dual-mode devices. Set the Bluetooth device ID to scan, which is a unique identifier for each vendor's Bluetooth device using a combination of vendor ID and Bluetooth product ID. By configuring the broadcast filter, you can select the second device that the master device needs to connect to.

[0175] For example, the first device needs to monitor Bluetooth headphones. These Bluetooth headphones may include, for example, True Wireless Stereo (TWS) headphones. Device information for the Bluetooth headphones may include: headphone type information, headphone connection identifiers, and / or manufacturer identification information, etc.

[0176] S102: The first device adds a broadcast to save configuration information through the firmware program. The broadcast to save configuration information is used to save the device information that has been acquired.

[0177] The capacity of the storage space can be set according to the broadcast save configuration, and the number of Bluetooth devices that the firmware program caches can be set.

[0178] When the number of device information entries stored in the storage space reaches the maximum limit, an update strategy is used to update the device information stored in the storage space. For example, the Least Recently Used (LRU) strategy can be used to update the device information stored in the storage space. This storage space can be a cache space.

[0179] S103: The Bluetooth application on the first device starts up, and reads the pre-obtained device information based on the broadcast saved configuration information.

[0180] For example, during firmware operation, based on broadcast filtering configuration information and broadcast saving configuration information, the monitored device information is saved in the corresponding storage space of the firmware.

[0181] S104: Based on the read device information, trigger Bluetooth connection and device authentication between the first device and the second device.

[0182] like Figure 6 As shown, this disclosure provides an information processing apparatus, the apparatus comprising:

[0183] The determination module 110 is used to determine the Bluetooth connection requirements of the first device;

[0184] The connection module 120 is used to establish a Bluetooth connection with the second device based on the device information of the second device that is saved in advance when it is determined that the first device has the Bluetooth connection requirement.

[0185] The information processing apparatus provided in this disclosure may include a first device.
