处理器31可以获取第一FEM 34的通信状态信息，例如是否进行Wi-Fi通信(或者，进行Wi-Fi通信或进行蓝牙通信)，处理器31还可以获取第二FEM 35的通信状态信息，例如是否进行蜂窝通信，处理器31还可以根据第一FEM 34的通信状态信息来通过SPI模块321向切换电路32中的控制器322发送第一控制命令或第二控制命令(具体见后文描述)，以通过切换电路32控制第二FEM 35在蜂窝通信状态与蓝牙通信状态之间切换。
控制器322用于根据来自处理器31的第一控制命令或第二控制命令控制旁路选通 电路325在旁路模式和非旁路模式之间切换。
具体的，上述无线通信电路可以执行本申请涉及的蓝牙通信切换方法，如图4所示，该方法包括：
S101、处理器31获取第一FEM 34的通信状态信息。
第一FEM 34的通信状态信息用于指示第一FEM 34是否进行Wi-Fi通信，或者说，第一FEM 34的通信状态信息用于指示第一FEM 34进行Wi-Fi通信或进行蓝牙通信。
S102、如果第一FEM 34的通信状态信息指示第一FEM 34进行Wi-Fi通信(或称建立Wi-Fi连接)，则处理器31向切换电路32中的控制器322发送第一控制命令。
第一控制命令用于控制切换电路32检测MDM 33是否向第二FEM 35发送MIPI命令，如果MDM 33未向第二FEM 35发送MIPI命令，则切换电路32控制第二FEM35进行蓝牙通信。
如图5的S1021-S1025所示的，在旁路模式下，如果切换电路32中的控制器322从处理器31接收到第一控制命令，则控制器322将模式切换寄存器配置为非旁路模式，并控制旁路选通电路325切换至非旁路模式。控制器322控制旁路选通电路325将MIPI从模块323与MDM 251导通并将MIPI主模块324与第二FEM 35导通，控制器322通过MIPI从模块323检测MDM 251是否向第二FEM 35发送MIPI命令。如果检测到MDM 251未向第二FEM 35发送MIPI命令(即MIPI总线空闲)，则控制器322通过MIPI主模块324向第二FEM 35发送第一MIPI命令，如果检测到MDM 251向第二FEM 35发送MIPI命令，则继续等待MIPI总线空闲。检测的来自MDM 251的MIPI命令可以是任意MIPI命令，第一MIPI命令用于指示第二FEM 35进行蓝牙通信。也就是说，在MDM 251未向第二FEM 35发送MIPI命令期间，控制器322将第二FEM35从蜂窝通信状态切换至蓝牙通信状态，以避免与MDM 251竞争MIPI总线，从而产生传输错误。
在控制器322通过MIPI主模块324向第二FEM 35发送第一MIPI命令，以指示第二FEM 35进行蓝牙通信之后，控制器322继续通过MIPI从模块323从MDM 251接收并缓存MIPI命令，待后续控制器322控制第二FEM 35切换回蓝牙通信状态时，将缓存的来自MDM 251的MIPI命令通过MIPI主模块324发送给第二FEM 35，使得MDM 251与第二FEM 35之间的控制逻辑在切换前后保持一致。
另外，由于某些场景下Wi-Fi连接不稳定，为了防止蓝牙通信在第一FEM 34和第二FEM 35之间频繁切换，处理器31可以根据第一FEM 34进行Wi-Fi通信的时间，判断是否对蓝牙通信进行切换；或者，处理器31可以根据预设时间内第一FEM 34在进行Wi-Fi通信和未进行Wi-Fi通信之间切换次数，判断是否对蓝牙通信进行切换。
在一种可能的实施方式中，如果第一FEM 34的通信状态信息指示第一FEM 34进行Wi-Fi通信，则在预设时间(例如一分钟)后，处理器31向切换电路32中的控制器322发送第一控制命令。即在电子设备稳定接入Wi-Fi连接预设时间后，处理器31向切换电路32中的控制器322发送第一控制命令，该方案的优点为判断条件简单并且从始至终不会出现频繁切换情况。
在另一种可能的实施方式中，如果第一FEM 34的通信状态信息指示第一FEM 34进行Wi-Fi通信，并且在第一预设时间(例如10秒)内第一FEM 34在进行Wi-Fi通 信和未进行Wi-Fi通信之间切换次数小于次数门限(例如三次)，则处理器31向切换电路32中的控制器322发送第一控制命令。如果在第一预设时间内第一FEM 34在进行Wi-Fi通信和未进行Wi-Fi通信之间切换次数大于或等于次数门限，则处理器31在第二预设时间(例如五分钟)后再从第一FEM 34获取通信状态信息，进而重新判断是否发送第一控制命令。该方案的优点为检测更加快速，在连接Wi-Fi后能尽快切换状态，体验感较好。
由于电子设备可以支持与多个其他设备进行蓝牙通信(或称配对)，所以此时处理器31可以将全部或部分蓝牙通信从第一FEM 34切换至第二FEM 35，以改善蓝牙通信质量。示例性的，如图6所示，可以通过电子设备的状态栏的蓝牙图标从A至B的变化，来提示这种蓝牙通信质量的改善，也可以通过下拉菜单中的蓝牙图标从C至D的变化，来提示这种蓝牙通信质量的改善，其中，A和C代表普通蓝牙通信功能，B和D代表增强蓝牙通信功能。如图7所示，可以通过点击下拉菜单中的蓝牙图标旁的三角图标，打开蓝牙配对界面，其中显示通过不同天线连接不同蓝牙设备。如图8所示，可以在蓝牙设置菜单中显示是否打开蓝牙增强功能开关，当蓝牙增强功能开关打开时，电子设备可以执行本申请的蓝牙通信切换方法，并且可以显示通过不同天线连接不同蓝牙设备；当蓝牙增强功能开关关闭时，电子设备不执行本申请的蓝牙通信切换方法。
S103、如果第一FEM 34的通信状态信息指示第一FEM 34未进行Wi-Fi通信(或称断开Wi-Fi连接)，则处理器31向切换电路32中的控制器322发送第二控制命令。
第二控制命令用于控制切换电路32检测MDM 33是否向第二FEM 35发送MIPI命令，如果MDM 33未向第二FEM 35发送MIPI命令，则切换电路32将MDM 33与第二FEM 35直通，使得MDM 33控制第二FEM 35进行蜂窝通信。
如图5的S1031-S1034所示的，在非旁路模式下，如果切换电路32中的控制器322从处理器31接收到第二控制命令，则控制器322将模式切换寄存器配置为旁路模式，并控制旁路选通电路325切换至旁路模式。此时，控制器322通过MIPI从模块323检测MDM 251是否向第二FEM 35发送MIPI命令。如果检测到MDM 251未向第二FEM 35发送MIPI命令(即MIPI总线空闲)，则控制器322控制旁路选通电路325将MDM 251与第二FEM 35直通，通过MIPI主模块324向第二FEM 35发送第二MIPI命令，第二MIPI命令用于指示第二FEM 35进行蜂窝通信。使得MDM 251能够控制第二FEM 35进行蜂窝通信，如果检测到MDM 251向第二FEM 35发送MIPI命令，则继续等待MIPI总线空闲。也就是说，在MDM 251未向第二FEM 35发送MIPI命令期间，控制器322将第二FEM 35从蓝牙通信状态切换至蜂窝通信状态，以避免与MDM 251竞争MIPI总线，从而产生传输错误。
在控制器322通过MIPI主模块324向第二FEM 35发送第二MIPI命令以指示第二FEM 35进行蜂窝通信之后，还要通过MIPI主模块324向第二FEM 35发送之前缓存的来自MDM 251的MIPI命令，使得MDM 251与第二FEM 35之间的控制逻辑在切换前后保持一致。
本申请实施例提供的无线通信电路、蓝牙通信切换方法和电子设备，第一FEM支持无线保真Wi-Fi通信或蓝牙通信，当第一FEM进行Wi-Fi通信，并且，MDM未向 第二FEM发送MIPI命令时，控制第二FEM进行蓝牙通信，从而将第一FEM的部分或全部蓝牙通信切换至较为空闲的第二FEM，避免Wi-Fi通信和蓝牙通信的分时复用挤占蓝牙通信的资源，提高蓝牙通信的通信质量。
