- the traditional Bluetooth can be a basic rate (basic rate, BR) Bluetooth, or an enhanced rate (enhanced data rate, EDR) Bluetooth.
- BR/EDR has a relatively high transmission rate, and can be applied to scenarios with a large amount of data, for example, can be applied to scenarios with a large amount of transmission data such as voice and music.
- BLE has the advantages of low power consumption and fast connection, but the transmission rate is lower than that of BR/EDR. Therefore, BLE can be applied to scenarios with high real-time requirements but low data transmission rate requirements, such as mouse and keyboard. , heart rate monitor and other scenarios where the amount of transmitted data is small.

In practical applications, the priority of establishing a BLE connection is generally higher. At this time, if the terminal If the transmission of BR data in the device is frequent, the transmission time slot of the BLE connection determined by the terminal device may be relatively late, resulting in the BLE connection timeout or connection failure, which cannot meet the actual communication needs.

目前,终端设备的蓝牙一般支持多连接,即同一终端设备可以与多个其他终端设备通过蓝牙进行通信。在多连接中,各蓝牙连接所对应的蓝牙通道共用蓝牙空口,因此,终端设备在处理某一蓝牙通信请求时,蓝牙空口可能已被其他蓝牙连接所占用,从而导致该蓝牙通信请求处理失败或处理时长过长,影响用户的使用体验。

本申请实施例中,可以根据第二终端设备对应的第一设备标识与第一终端设备中已有蓝牙连接所连终端设备对应的第二设备标识来确定第二终端设备是否已与第一终端设备建立蓝牙连接。当第二终端设备未与第一终端设备建立蓝牙连接时,则可以确定第二终端设备为与第一终端设备进行通信的新设备,此时第一终端设备则可以直接根据蓝牙通信请求中的数据传输标识来确定第一终端设备对应的蓝牙工作模式。当第二终端设备已与第一终端设备建立蓝牙连接时,第一终端设备则可以根据第二终端设备与第一终端设备之间已建立蓝牙连接的蓝牙类型和蓝牙通信请求中的数据传输标识来确定第一终端设备对应的蓝牙工作模式。
具体地,所述根据所述蓝牙类型和所述蓝牙通信请求中的数据传输标识确定所述第一终端设备对应的蓝牙工作模式,可以包括:

根据所述连接优先模式调整所述第一终端设备中蓝牙的工作参数,并利用工作参数调整后的蓝牙建立所述第一终端设备与所述第二终端设备之间的传统蓝牙连接;
在确定所述第一终端设备与所述第二终端设备之间的传统蓝牙连接建立后,根据所述传输优先模式调整所述第一终端设备中蓝牙的工作参数,并利用所建立的传统蓝牙连接进行所述第一终端设备与所述第二终端设备之间的数据传输。
本申请实施例中,当第二终端设备与第一终端设备之间已建立的蓝牙连接为BLE时,即表示第二终端设备与第一终端设备已建立的蓝牙连接只能进行较小数据量的传输,而此时若蓝牙通信请求中的数据传输标识为需传输较大数据量的第二预设标识时,则表明第二终端设备与第一终端设备之间已建立的蓝牙连接不能满足此次的蓝牙通信请求,因此,第一终端设备可以确定第一终端设备对应的蓝牙工作模式为连接优先模式和传输优先模式,以通过连接优先模式来建立第二终端设备与第一终端设备之间可进行较大数据量传输的BR/EDR连接,然后可以通过所建立的BR/EDR连接来进行第一终端设备与第二终端设备之间较大 数据量的传输。当第二终端设备与第一终端设备之间已建立的蓝牙连接为BR/EDR时,即表示第二终端设备与第一终端设备已建立的蓝牙连接可进行较大数据量的传输,而此时若蓝牙通信请求中的数据传输标识为需传输较大数据量的第二预设标识时,则表明第二终端设备与第一终端设备之间已建立的蓝牙连接可以满足此次的蓝牙通信请求,因此,第一终端设备可以确定第一终端设备对应的蓝牙工作模式为传输优先模式,以直接通过第一终端设备与第二终端设备之间已有的BR/EDR连接来进行较大数据量的传输。
在第一方面的一种可能的实现方式中,当获取到多个第二终端设备对应的蓝牙通信请求时,所述根据所述蓝牙通信请求和所述已有蓝牙连接的连接信息确定所述第一终端设备对应的蓝牙工作模式,可以包括:
根据各所述蓝牙通信请求和所述已有蓝牙连接的连接信息分别确定所述第一终端设备对应的蓝牙工作模式;
所述根据所述蓝牙工作模式调整所述第一终端设备中蓝牙的工作参数,并利用工作参数调整后的蓝牙与所述第二终端设备进行通信包括:
当各所述蓝牙工作模式为同一种蓝牙工作模式时,根据所述蓝牙工作模式调整所述第一终端设备中蓝牙的工作参数,并利用工作参数调整后的蓝牙与各所述第二终端设备进行通信;
当各所述蓝牙工作模式包括连接优先模式和传输优先模式时,根据所述连接优先模式调整所述第一终端设备中蓝牙的工作参数,并利用工作参数调整后的蓝牙建立所述第一终端设备与所有请求建立蓝牙连接的第二终端设备之间的蓝牙连接;
在确定所述第一终端设备与所有请求建立蓝牙连接的第二终端设备之间的蓝牙连接均建立后,根据所述传输优先模式调整所述第一终端设备中蓝牙的工作参数,并利用工作参数调整后的蓝牙进行数据传输。
需要说明的是,当第一终端设备同时接收到多个第二终端设备的蓝牙通信请求时,第一终端设备可以根据第一终端设备中已有蓝牙连接的连接信息和各第二终端设备的蓝牙通信请求分别确定第一终端设备所对应的蓝牙工作模式。当根据各蓝牙通信请求所确定的蓝牙工作模式为同一种蓝牙工作模式时,第一终端设备可以直接根据该蓝牙工作模式调整第一终端设备中蓝牙的工作参数,从而处理各第二终端设备对应的蓝牙通信请求。当根据各蓝牙通信请求所确定的蓝牙工作模式不相同时,第一终端设备则可以根据所确定的各蓝牙工作模式之间的优先级来切换第一终端设备对应的蓝牙工作模式,即可以根据优先级以及优先级对应的蓝牙工作模式依次进行第一终端设备中蓝牙的工作参数的调整。
本申请实施例中,当第一终端设备在预设时长内未获取到蓝牙通信请求,且第一终端设备当前也无正在进行数据传输的蓝牙通道时,第一终端设备则可以确定第一终端设备对应的蓝牙工作模式为普通模式,此时,第一终端设备可以将第一终端设备对应的蓝牙工作模式切换至普通模式,即根据普通模式对应的工作参数来调整第一终端设备中蓝牙的工作参数。其中,普通模式为第一终端设备中蓝牙常驻的工作模式。

蓝牙(Bluetooth,BT)是一种在全球范围内广泛应用的无线通信技术,运行于2.4GHz至2.485GHz的开放频段,普遍应用于1米至10米的短距离无线传输。BT可以包括传统蓝牙和低功耗蓝牙(bluetooth low energy,BLE)。传统蓝牙可以是基本速率(basic rate,BR)蓝牙,也可以是增强速率(enhanced data rate,EDR)蓝牙。其中,BR/EDR具有相对较高的传输速率,可以适用于数据量较大的场景,例如,可以适用于语音、音乐等传输数据量较大的场景。BLE具有功耗低、连接迅速等优点,但传输速率较BR/EDR低, 因此,BLE可以适用于实时性要求较高但对数据传输速率要求较低的场景,例如,可以适用于鼠标、键盘、心率计等传输数据量较小的场景。
目前,终端设备的蓝牙一般支持多连接,即同一终端设备可以通过蓝牙与多个其他终端设备进行蓝牙通信(如进行蓝牙连接与数据传输等)。在多连接的情况中,各蓝牙连接所对应的蓝牙通道共用蓝牙空口,即各蓝牙通道需要共用同一个蓝牙空口来进行数据传输等,因此,在终端设备获取到新的蓝牙通信请求时,若该终端设备中已存在蓝牙连接,则蓝牙空口可能已被已存在的蓝牙连接所占用,使得终端设备基于新的蓝牙通信请求进行蓝牙连接与传输时可能与已存在的蓝牙连接之间存在占用蓝牙空口资源的冲突,从而可能导致该蓝牙通信请求处理失败或处理时长过长,影响用户的使用体验。
另外,随着终端技术和蓝牙技术的快速发展,手机、平板等硬件资源较为丰富的终端设备可集成有双模蓝牙芯片,双模蓝牙芯片能够同时支持BLE和BR/EDR。其中,BLE由于功耗低、连接迅速等优点,常用于设备间的发现连接与组网。BR/EDR由于其传输速率相对较高的特点,常用于设备间的数据传输。但是在芯片层面,BLE与BR/EDR也共用蓝牙空口,即BLE通道与BR/EDR通道也需要共用同一个蓝牙空口来进行数据传输等,因此,在终端设备获取到新的蓝牙通信请求(例如BR数据传输请求)时,若该终端设备中已存在蓝牙连接(例如BLE连接),则蓝牙空口可能已被已存在的BLE连接所占用,使得BR数据传输可能与已存在的BLE连接之间存在占用蓝牙空口资源的冲突,从而可能导致BR数据传输失败或者传输时间过长等,影响用户的使用体验。
现有技术中,可以通过调整时隙的方式来减少蓝牙通道之间的冲突。即当终端设备接收到某一终端设备发送的广播包时,终端设备可以获取广播包的时间位置,并可以根据时间位置对BLE连接事件的发送时隙进行调整,使得调整后的BLE连接事件的发送时隙位于BR/EDR同步数据链路包所未占用的发送时隙。
上述方式仅考虑了BLE连接与BR数据传输之间可能存在的占用蓝牙空口资源的冲突,对于BLE广播、BLE扫描等与BR传输、BLE连接之间可能存在的冲突并未涉及。另外,上述方式仅适用于一对一连接的终端设备,当终端设备存在一对多连接时,蓝牙空口间隙有限,调整时隙的方式可能并不能找到未占用的空闲时隙。另外,上述方式是基于蓝牙芯片层与蓝牙协议栈层来进行时隙的调整,未考虑实际应用中蓝牙通信请求的优先级,实际应用中建立BLE连接的优先级一般较高,此时若终端设备中BR数据传输的发包较为频繁,则终端设备所确定出的BLE连接的发送时隙可能会相对较晚,导致BLE连接超时或连接失败,无法满足实际的通信需求。
为解决上述问题,本申请实施例提供了一种蓝牙通信方法、终端设备及计算机可读存储介质。该方法中,第一终端设备在获取到第二终端设备对应的蓝牙通信请求时,可以获取第一终端设备中已有蓝牙连接的连接信息,并可以根据蓝牙通信请求和已有蓝牙连接的连接信息确定第一终端设备当前对应的蓝牙工作模式。然后可以根据该蓝牙工作模式来调整蓝牙的工作参数,并可以利用工作参数调整后的蓝牙与第二终端设备进行通信,以通过调整蓝牙的工作参数,来调整已有蓝牙连接当前对蓝牙空口的占用,减少蓝牙多连接中蓝牙空口资源的冲突问题,可以为第一终端设备处理新获取的蓝牙通信请求提供充足、稳定的蓝牙空口资源,确保该蓝牙通信请求得到及时有效处理,提高该蓝牙通信请求的处理效率和成功率,满足用户实际的通信需求,提升用户的使用体验,具有较强的易用性和实用性。
本申请实施例中,终端设备(包括上述的第一终端设备和第二终端设备)为具备蓝牙通信功能的终端设备。其中,终端设备可以为手机、平板电脑、可穿戴设备、车载设备、增强现实(augmented reality,AR)/虚拟现实(virtual reality,VR)设备、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer,UMPC)、上网本、个人数字助理(personal digital assistant,PDA)、桌上型计算机等,本申请实施例对终端设备的具体类型不作任何限制。

以下将结合附图对本申请实施例提供的蓝牙通信方法进行详细说明。如图3中的(a)所示,本申请实施例提供的蓝牙通信方法可以应用于终端设备与其他多个终端设备之间利用单一蓝牙(例如BLE)进行组网、通信的场景。如图3中的(b)所示,本申请实施例提供的蓝牙通信方法也可以应用于终端设备与其他多个终端设备之间同时利用BLE和BR/EDR进行连接和数据传输的场景。以下将以图3中的(b)所示的场景为例进行示例性说明。
本申请实施例中,可以事先根据蓝牙通信请求和已有蓝牙连接等因素将终端设备对应的蓝牙工作模式划分为连接优先模式、传输优先模式和普通模式三种模式,并配置各蓝牙工作模式所对应的预设工作参数, 然后可以将各蓝牙工作模式分别与所对应的预设工作参数关联保存于终端设备或与终端设备通信连接的云端等第三方存储装置。其中,蓝牙通信请求可以是蓝牙连接请求,也可以是蓝牙传输请求。已有蓝牙连接是指终端设备已与其他终端设备建立蓝牙连接进行蓝牙通信,所建立的蓝牙连接可以是BLE连接,也可以是BR/DER连接。预设工作参数可以包括BLE连接的连接间隔、BLE连接的连接超时时间、BLE广播的广播周期、BLE广播的单次广播持续时长、BLE广播的广播间隔、BLE扫描的扫描窗口比值和BR/EDR连接的传输状态等中的至少一个。
应理解,连接间隔是指两个连接事件之间的时间间隔,连接事件是指已建立蓝牙连接的两终端设备之间相互发送数据包的过程。连接超时时间是指已建立蓝牙连接的两终端设备在连接期间内没有发生通信而导致连接自动断开的时间。单次广播持续时长是指在一个广播周期内进行广播的时长,广播间隔是指在单次广播持续时长内两个广播事件之间的时间间隔。扫描窗口是指一次扫描进行的时间,扫描窗口比值是指扫描窗口占扫描间隔的时间比值,扫描间隔是指两个扫描窗口之间的时间间隔,扫描间隔可以包括扫描休息时间和扫描进行时间(即扫描窗口)。例如,在扫描窗口比值为1/10,扫描间隔为10ms时,则表明终端设备在这10ms的时间内,只需进行1ms的蓝牙扫描。
在连接优先模式中,可以为BLE连接设置较长的连接间隔,和/或可以为BLE连接设置较长的连接超时时间,以通过延长BLE连接的连接间隔和/或连接超时时间,来调整已有BLE通道当前对蓝牙空口的占用,减少已有BLE连接对新建蓝牙连接的影响,即减少已有蓝牙连接与新建蓝牙连接使用蓝牙空口资源时的冲突问题,可以为终端设备处理新建蓝牙连接提供充足的蓝牙空口资源,以为新建蓝牙连接提供稳定、可靠的蓝牙连接能力,有助于终端设备优先进行新蓝牙连接的建立,满足实际的通信需求,提升用户的使用体验。示例性的,可以将BLE连接的连接间隔设置为N*250ms(1≤N≤4),例如,可以设置为500ms。可以将BLE连接的连接超时时间设置为10s。
可选地,在连接优先模式中,若终端设备中存在BLE广播,还可以为BLE广播设置较小的广播间隔,从而有助于快速进行蓝牙发现与连接。示例性的,可以将BLE广播的广播间隔设置为20ms。
可选地,在连接优先模式中,若终端设备中存在BLE扫描,还可以为BLE扫描设置较大的扫描窗口比值,有助于快速进行蓝牙发现与连接。示例性的,可以将BLE扫描的扫描窗口比值设置为1/10。
可选地,在连接优先模式中,若终端设备中存在BR/EDR通道正在进行数据传输,终端设备还可以先暂停该BR/EDR通道的数据传输,以通过暂停已有BR/EDR通道的数据传输,来调整已有BR/EDR通道当前对蓝牙空口的占用,从而减少已有BR/EDR连接对新建蓝牙连接的影响,可以为终端设备处理新建蓝牙连接提供充足的蓝牙空口资源,以为新建蓝牙连接提供稳定、可靠的蓝牙连接能力,有助于终端设备优先进行新蓝牙连接的建立,满足用户实际的通信需求。应理解,在新请求的蓝牙连接建立完毕后,终端设备可以恢复该BR/EDR通道的数据传输。
需要说明的是,上述描述的将BLE连接的连接超时时间设置为10s、将BLE广播的广播间隔设置为20ms、将BLE扫描的扫描窗口比值设置为1/10等仅作示意性解释,不应理解为对本申请实施例的限制,本申请实施例中,当然可以根据实际情况将BLE连接的连接超时时间、将BLE广播的广播间隔、将BLE扫描的扫描窗口比值等设置为其他数值。
在传输优先模式中,因数据传输主要依赖于BR/EDR连接,因此可以通过调整BLE连接的参数来降低已有BLE连接对BR/EDR通道进行数据传输的影响。具体地,可以为BLE连接设置较长的连接间隔和/或连接超时时间,来减少BLE连接对蓝牙空口的占用,从而为终端设备提供更多空闲的蓝牙空口来进行数据传输。因数据传输所需的时间较蓝牙连接长,因此在传输优先模式中,为BLE连接设置的连接间隔可以大于连接优先模式中为BLE连接设置的连接间隔。同样的,在传输优先模式中,为BLE连接设置的连接 超时时间可以大于连接优先模式中为BLE连接设置的连接超时时间。示例性的,可以将BLE连接的连接间隔设置为M×200ms(5≤M≤10),可以将BLE连接的连接超时时间设置为32s。
可选地,在传输优先模式中,若终端设备中存在BLE广播,还可以为BLE广播设置较长的广播间隔,以减少BLE广播对BR/EDR通道进行数据传输的影响。示例性的,可以将BLE广播的广播间隔设置为S×50ms(1≤S≤10)。
可选地,在传输优先模式中,若终端设备中存在BLE扫描,还可以为BLE扫描设置较小的扫描窗口比值,降低BLE的扫描时间,以减少BLE扫描对BR/EDR通道进行数据传输的影响。示例性的,可以将BLE扫描的扫描窗口比值设置为1/50。
需要说明的是,在传输优先模式中,当终端设备中已有BR/EDR通道正在进行数据传输时,终端设备则可以查找该BR/EDR通道进行数据传输的时隙,并可以在该BR/EDR通道未占用的时隙来进行新传输请求的数据传输。
在普通模式中,可以将BLE连接的连接间隔设置为R×100ms(1≤R≤10),可以将蓝牙(如BLE)的广播周期设置为T*100s(1≤T≤5),例如可以设置为300s,还可以将蓝牙广播的单次广播持续时长设置为10s至20s,例如可以设置为10s。其中,普通模式可以为终端设备常驻的蓝牙工作模式。
可选地,在普通模式中,当已建立的BR/EDR连接在第一预设时长内没有数据传输时,还可以断开该BR/EDR连接。其中,第一预设时长可以根据实际情况具体设置,例如可以设置为20s。
可选地,在普通模式中,当已建立的BR/EDR连接和BLE连接在第二预设时长内均无数据传输时,可以控制终端设备中的蓝牙芯片进入呼吸模式(sniff mode)。其中,第二预设时长可以根据实际情况设置,例如可以设置为500ms。
可选地,在普通模式中,当终端设备在第三预设时长内没有获取到蓝牙通信请求时,可以控制终端设备中的蓝牙芯片进入保持模式(hold mode)。其中,第三预设时长可以根据实际情况具体设置,例如可以设置为200s。
本申请实施例中,第一终端设备获取到第二终端设备对应的蓝牙通信请求时,可以获取第一终端设备中已有蓝牙连接的连接信息。第二终端设备对应的蓝牙通信请求可以是第二终端设备向第一终端设备发送的、请求与第一终端设备进行通信的蓝牙通信请求,也可以是第一终端设备生成的、与第二终端设备进行通信的蓝牙通信请求。其中,蓝牙通信请求中可以携带有数据传输标识和第二终端设备对应的设备标识。数据传输标识可以用于表明蓝牙通信的传输数据量,第一终端设备可以根据传输数据量来确定此次蓝牙通信所需的蓝牙类型。例如,当传输数据量较大时,第一终端设备可以确定此次蓝牙通信所需的蓝牙类型为BR/EDR;当传输数据量较小时,第一终端设备可以确定此次蓝牙通信所需的蓝牙类型为BLE。示例性的,数据传输标识可以为1(即权利要求中所述的第二预设标识)或0(即权利要求中所述的第一预设标识),1用于表示传输数据量大于32KB的较大数据传输,0用于表示传输数据量小于或等于32KB的较小传输数据。设备标识可以为设备唯一编码(Identity document,ID)和/或设备名称等标识。
应理解,已有蓝牙连接的连接信息可以包括已有蓝牙连接的连接数量、蓝牙类型、各蓝牙连接所连的终端设备和连接状态等。当已有蓝牙连接包括BLE连接时,已有蓝牙连接的连接信息还可以包括BLE连接的连接间隔、从设备时延、连接超时时间等。当已有蓝牙连接包括BR/EDR连接时,已有蓝牙连接的连接信息还可以包括BR/EDR连接的主从设备、发包间隔、异步无连接链路(asynchronous connectionless,ACL)包类型等。其中,蓝牙类型可以包括BLE和BR/EDR。各蓝牙连接所连的终端设备是指第一终端设备通过蓝牙所连接的其他终端设备,可以通过各其他终端设备对应的设备标识表示,例如可以通过各其他终端设备对应的设备ID来表示。
另外,第一终端设备获取到第二终端设备对应的蓝牙通信请求后,还可以获取第一终端设备中蓝牙的广播间隔等广播参数和/或蓝牙扫描的扫描窗口比值等扫描参数。可以理解的是,为了降低第一终端设备的功耗,第一终端设备中主要通过低功耗的BLE来进行广播和/或扫描,因此,第一终端设备获取到第二终端设备对应的蓝牙通信请求后,可以获取BLE广播的广播间隔等广播参数,和/或获取BLE扫描的扫描窗口比值等扫描参数。
本申请实施例中,第一终端设备获取到第一终端设备中已有蓝牙连接的连接信息后,可根据所获取的蓝牙通信请求和连接信息确定第一终端设备所对应的蓝牙工作模式。其中,所确定的第一终端设备对应的蓝牙工作模式为事先设置的连接优先模式、传输优先模式和普通模式中的至少一种。
需要说明的是,本申请实施例中,普通模式为第一终端设备常驻的蓝牙工作模式,连接优先模式的优先级高于传输优先模式的优先级,即当确定第一终端设备对应的蓝牙工作模式为连接优先模式和传输优先模式时,则第一终端设备可以优先将第一终端设备对应的蓝牙工作模式切换至连接优先模式。在连接优先模式中处理完对应的蓝牙通信请求后,第一终端设备可以再将第一终端设备对应的蓝牙工作模式切换至传输优先模式。
示例性的,第一终端设备可以先将蓝牙通信请求中的设备标识(以下将蓝牙通信请求中的设备标识称为第一设备标识)与各蓝牙连接所连终端设备对应的设备标识(以下将蓝牙连接所连终端设备对应的设备标识称为第二设备标识)进行匹配,以根据第一设备标识是否匹配到对应的第二设备标识,来确定第二终端设备是否已与第一终端设备建立蓝牙连接。当未匹配到与第一设备标识相同的第二设备标识时,第一终端设备可以确定第二终端设备未曾与第一终端设备建立蓝牙连接,即确定第二终端设备为与第一终端设备进行蓝牙通信的新设备,此时,第一终端设备可以根据蓝牙通信请求中携带的数据传输标识来确定第一终端设备中蓝牙的工作模式。
具体地,当蓝牙通信请求中的数据传输标识为0时,第一终端设备可以确定第一终端设备对应的蓝牙工作模式为连接优先模式,即第一终端设备可以将第一终端设备对应的蓝牙工作模式切换至连接优先模式,以根据连接优先模式对应的预设工作参数调整第一终端设备中蓝牙的工作参数,例如,调整第一终端设备中已有BLE连接的连接间隔至500ms、调整已有BLE连接的连接超时时间至10s、调整BLE广播的广播间隔至20ms、调整BLE扫描的扫描窗口比值至1/10以及暂停已连接的BR/EDR通道正在进行的数据传输等。然后,第一终端设备可以利用工作参数调整后的蓝牙来建立与第二终端设备之间的BLE连接。
当蓝牙通信请求中的数据传输标识为1时,第一终端设备可以确定第一终端设备对应的蓝牙工作模式为连接优先模式和传输优先模式,此时,第一终端设备可以先将第一终端设备对应的蓝牙工作模式切换至连接优先模式,以根据连接优先模式对应的预设工作参数调整第一终端设备中蓝牙的工作参数。然后,第一终端设备可以利用工作参数调整后的蓝牙来建立与第二终端设备之间的BR/EDR连接,并在建立与第二终端设备之间的BR/EDR连接后,第一终端设备可随即将第一终端设备对应的蓝牙工作模式切换至传输优先模式,以根据传输优先模式对应的预设工作参数进一步调整第一终端设备中蓝牙的工作参数,例如,调整第一终端设备中已有BLE连接的连接间隔至1200ms、调整已有BLE连接的连接超时时间至32s、调整BLE广播的广播间隔至100ms以及调整BLE扫描的扫描窗口比值至1/50等。在蓝牙的工作参数调整后,第一终端设备可以利用所建立的BR/EDR连接来进行第一终端设备与第二终端设备之间的数据传输。
应理解,当匹配到与第一设备标识相同的第二设备标识时,第一终端设备可以获取第一终端设备与第二终端设备之间已有蓝牙连接的蓝牙类型,并可以根据蓝牙类型和蓝牙通信请求中的数据传输标识确定第一终端设备对应的蓝牙工作模式。
具体地,当确定第一终端设备与第二终端设备之间的蓝牙类型为BLE,且蓝牙通信请求中的数据传输 标识为1时,第一终端设备可以确定第一终端设备对应的蓝牙工作模式为连接优先模式和传输优先模式,此时第一终端设备可以先将第一终端设备对应的蓝牙工作模式切换至连接优先模式,以根据连接优先模式对应的预设工作参数调整第一终端设备中蓝牙的工作参数。然后,可以利用工作参数调整后的蓝牙来建立第一终端设备与第二终端设备之间的BR/EDR连接。在建立第一终端设备与第二终端设备之间的BR/EDR连接后,第一终端设备可随即将第一终端设备对应的蓝牙工作模式切换至传输优先模式,以根据传输优先模式对应的预设工作参数进一步调整第一终端设备中蓝牙的工作参数。在蓝牙的工作参数调整后,第一终端设备可以利用所建立的BR/EDR连接来进行第一终端设备与第二终端设备之间的数据传输。
当确定第一终端设备与第二终端设备之间的蓝牙类型为BR/EDR,且蓝牙通信请求中的数据传输标识为1时,第一终端设备可以确定第一终端设备对应的蓝牙工作模式为传输优先模式,此时,第一终端设备可以直接将第一终端设备对应的蓝牙工作模式切换至传输优先模式,以根据传输优先模式对应的预设工作参数调整第一终端设备中蓝牙的工作参数。在蓝牙的工作参数调整后,第一终端设备可以利用第一终端设备与第二终端设备之间已有的BR/EDR连接来进行第一终端设备与第二终端设备之间的数据传输。
需要说明的是,当第一终端设备同时获取到多个第二终端设备对应的蓝牙通信请求时,第一终端设备可以根据第一终端设备中已有蓝牙连接的连接信息和各第二终端设备的蓝牙通信请求分别确定第一终端设备所对应的蓝牙工作模式。例如,当第一终端设备同时接收到第二终端设备A和第二终端设备B的蓝牙通信请求时,第一终端设备可以根据第一终端设备中已有蓝牙连接的连接信息和第二终端设备A对应的蓝牙通信请求确定第一终端设备对应的蓝牙工作模式A,同时可以根据第一终端设备中已有蓝牙连接的连接信息和第二终端设备B对应的蓝牙通信请求确定第一终端设备对应的蓝牙工作模式B。当根据各蓝牙通信请求所确定的蓝牙工作模式为同一种蓝牙工作模式时,第一终端设备可以直接切换至该蓝牙工作模式来处理各第二终端设备对应的蓝牙通信请求。例如,当蓝牙工作模式A和蓝牙工作模式B都为传输优先模式时,第一终端设备可以直接将第一终端设备对应的蓝牙工作模式切换至传输优先模式,以根据传输优先模式对应的预设工作参数调整第一终端设备中蓝牙的工作参数,并可以在蓝牙的工作参数调整后,利用第一终端设备与第二终端设备A之间已有的BR/EDR连接来进行第一终端设备与第二终端设备B之间的数据传输,以及利用第一终端设备与第二终端设备B之间已有的BR/EDR连接来进行第一终端设备与第二终端设备B之间的数据传输。
当根据各蓝牙通信请求所确定的蓝牙工作模式不相同时,第一终端设备则可以根据所确定的各蓝牙工作模式之间的优先级来切换第一终端设备对应的蓝牙工作模式。例如,当蓝牙工作模式A为连接优先模式,而蓝牙工作模式B为连接优先模式和传输优先模式时,因连接优先模式的优先级高于传输优先模式的优先级,因此第一终端设备可以先将第一终端设备对应的蓝牙工作模式切换至连接优先模式,以根据连接优先模式对应的预设工作参数调整第一终端设备中蓝牙的工作参数,并可以在蓝牙的工作参数调整后,建立第一终端设备与第二终端设备A之间的蓝牙连接以及建立第一终端设备与第二终端设备B之间的蓝牙连接。在确定第一终端设备与第二终端设备A之间的蓝牙连接以及第一终端设备与第二终端设备B之间的蓝牙连接均建立完后,第一终端设备可以再将第一终端设备对应的蓝牙工作模式由连接优先模式切换至传输优先模式,以根据传输优先模式对应的预设工作参数调整第一终端设备中蓝牙的工作参数,并可以在蓝牙的工作参数调整后,利用第一终端设备与第二终端设备B之间的BR/EDR连接来进行第一终端设备与第二终端设备B之间的数据传输。
本申请实施例中,当第一终端设备在第四预设时长内未获取到蓝牙通信请求,且第一终端设备当前也无正在进行数据传输的蓝牙通道时,第一终端设备可以确定第一终端设备对应的蓝牙工作模式为普通模式,此时第一终端设备可以将第一终端设备对应的蓝牙工作模式切换至普通模式,以根据普通模式对应的预设 工作参数来调整第一终端设备中蓝牙的工作参数,例如调整第一终端设备中已有BLE连接的连接间隔至200ms、调整BLE广播的广播周期至300s以及调整BLE广播的单次广播持续时长至10s等。其中,第四预设时长可以根据实际情况具体设置,例如可以设置为30s。
以下结合具体应用场景来对本申请实施例提供的蓝牙通信方法进行说明。
如图4所示,在第一终端设备401与第二终端设备402、第一终端设备401与第二终端设备403之间均没有建立蓝牙连接的场景中,当第二终端设备402和第二终端设备403分别向第一终端设备401发送蓝牙连接请求,以请求与第一终端设备401组网(组网为设备信息交换,仅需传输少量数据,BLE由于功耗低、连接迅速等优点,常用于设备间的发现连接与组网,即请求组网时,第二终端设备402和第二终端设备403所发送的蓝牙连接请求中的数据传输标识均为0)时,第一终端设备401可以获取第一终端设备401中已有蓝牙连接的连接信息。随后,第一终端设备401可以根据已有蓝牙连接的连接信息和第二终端设备402发送的蓝牙连接请求确定出第二终端设备402未曾与第一终端设备401建立蓝牙连接,以及根据已有蓝牙连接的连接信息和第二终端设备403发送的蓝牙连接请求确定出第二终端设备403未曾与第一终端设备401建立蓝牙连接,且确定第二终端设备402和第二终端设备403所发送的蓝牙连接请求中的数据传输标识均为0时,第一终端设备401可以确定需要与第二终端设备402、第二终端设备403建立BLE连接,此时第一终端设备401可以将第一终端设备401对应的蓝牙工作模式由初始时的普通模式切换至连接优先模式,来建立与第二终端设备402以及第二终端设备403之间的BLE连接。
其中,在进行BLE连接的建立时,第一终端设备401可以先建立第一终端设备401与第二终端设备402之间的BLE连接,此时,因第一终端设备401中不存在已有蓝牙连接,因此第一终端设备401可以直接建立第一终端设备401与第二终端设备402之间的BLE连接,而不需要对第一终端设备401中已有蓝牙连接进行参数调整。在建立完第一终端设备401与第二终端设备402之间的BLE连接后,第一终端设备401可以继续建立第一终端设备401与第二终端设备403之间的BLE连接,此时因第一终端设备401中存在已有蓝牙连接(即第一终端设备401与第二终端设备402之间的BLE连接),因此第一终端设备401可以先根据连接优先模式对应的预设工作参数调整第一终端设备中蓝牙的工作参数,例如调整第一终端设备401与第二终端设备402之间已建立的BLE连接的连接间隔、连接超时时间等。在蓝牙的工作参数调整后,第一终端设备401可以继续建立第一终端设备401与第二终端设备403之间的BLE连接。
应理解,在第一终端设备401与第二终端设备402,以及第一终端设备401与第二终端设备403之间的BLE连接均建立完成后,若第一终端设备401需要向第二终端设备402分享数据量较大的数据,则第一终端设备401可以生成向第二终端设备402发送数据的蓝牙传输请求,该蓝牙传输请求中的数据传输标识为1,设备标识为第二终端设备402对应的设备标识。随后,第一终端设备401根据该蓝牙传输请求和第一终端设备401中已有蓝牙连接的连接信息,可以确定出第一终端设备401对应的蓝牙工作模式为连接优先模式和传输优先模式,此时第一终端设备401可以根据连接优先模式对应的预设工作参数调整第一终端设备中蓝牙的工作参数,例如调整第一终端设备401与第二终端设备402之间的BLE连接的连接间隔和连接超时时间等、调整第一终端设备401与第二终端设备403之间的BLE连接的连接间隔和连接超时时间等,以及调整BLE广播的广播间隔等广播参数和BLE扫描的扫描窗口比值等扫描参数。在蓝牙的工作参数调整完后,第一终端设备401可以建立与第二终端设备402之间的BR/EDR连接。在第一终端设备401与第二终端设备402之间的BR/EDR连接建立完后,第一终端设备可以将第一终端设备401由连接优先模式切换至传输优先模式,以根据传输优先模式对应的预设工作参数调整第一终端设备中蓝牙的工作参数。然后,第一终端设备401可以根据所建立的BR/EDR连接来向第二终端设备402传输数据。
应理解,当第一终端设备401与第二终端设备402之间的数据传输完毕后,若第一终端设备401在30s 内未获取到蓝牙通信请求,则第一终端设备401可以将第一终端设备401对应的蓝牙工作模式由传输优先模式切换至普通模式。
基于上述的描述,以下将对本申请实施例提供的一种蓝牙通信方法进行简要说明。请参阅图5,图5示出了本申请实施例提供的蓝牙通信方法的流程示意图,该方法可以应用于第一终端设备。如图5所示,该方法可以包括:

S503、根据所述蓝牙工作模式调整所述第一终端设备中蓝牙的工作参数,并利用工作参数调整后的蓝牙与所述第二终端设备进行通信。
本申请实施例中,第一终端设备获取到第二终端设备对应的蓝牙通信请求后,可以根据该蓝牙通信请求和第一终端设备中已有蓝牙连接的连接信息确定第一终端设备当前对应的蓝牙工作模式,以根据该蓝牙工作模式来调整蓝牙的工作参数,从而调整第一终端设备中已有蓝牙连接当前对蓝牙空口的占用,减少蓝牙多连接中蓝牙空口资源的冲突问题,可以为第一终端设备处理该蓝牙通信请求提供充足、稳定的蓝牙空口资源,确保该蓝牙通信请求得到及时有效处理,提高该蓝牙通信请求的处理效率和成功率,满足用户实际的通信需求,提升用户的使用体验,具有较强的易用性和实用性。
应理解,上述实施例中各步骤的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本申请实施例的实施过程构成任何限定。
