SBC-T113S产品功能评估图：
蓝牙测试：
SBC-T113S主板使用的是RTL8723DU Wi-Fi & BT模块，该模块支持BT的版本为BT4.2。该模块通过USB信号与SBC-T113S主板通讯。
判断蓝牙是否正常工作：
首先确认bt模块的驱动是否已经正常工作，通过lsmod来判断，如下信息中表示8723du的bt已经正常工作。
root@T113-Embfly:/userdata# lsmod
root@T113-Embfly:~# lsmod
Module Size Used by Not tainted
8723du 2162688 0
rtk_btusb 65536 0
sunxi_ce 57344 0
ch343 24576 0
cdc_acm 24576 0
hid_multitouch 20480 0
如果通过lsmod指令未发现可用的bt驱动（rtk_btusb），则可以通过insmod指令进行驱动插入，bt的驱动在/lib/modules/5.4.61/目录。另外，bt的驱动还需要两个配置文件，当bt驱动加载时，务必保证rtl8723du_config 和rtl8723du_fw两个文件在/lib/firmware/的目录下，否则bt驱动加载不成功。驱动加载正确的信息如下：

蓝牙工具软件bluetoothctl的介绍和使用
bluetoothctl 是一个交互式且易于使用的工具，用于控制蓝牙设备。它是在基于 Linux 的操作系统上管理蓝牙的主要实用程序。本指南将向您展示如何使用 bluetoothctl 在主板上设置蓝牙设备和连接。
- 扫描附近的设备
要主动搜索可以连接的蓝牙设备，请使用扫描命令，如下所示：
Target#bluetoothctl scan on
当您运行上述命令时，您的电脑将查找并列出系统范围内的所有蓝牙设备。
root@T113-Embfly:# bluetoothctl scan on

所有蓝牙设备都标记为设备，后跟各自的媒体访问控制 (MAC) 地址，这是网络上设备的唯一标识符。 MAC 地址遵循格式 XX : XX : XX : XX : XX : XX。 Bluetoothctl 还显示设备的名称，例如上面输出中的 EDIFIER M350（我们测试使用的蓝牙音箱）。
注意：如果您找不到所需的蓝牙设备，请确保您的系统蓝牙可被发现。
要使其他设备可以发现您的蓝牙适配器，请使用以下命令：
bluetoothctl discoverable on
- 连接到您的设备
现在您已经有了可以连接的蓝牙设备列表，可以使用 MAC 地址连接到特定设备。
连接蓝牙设备的最简单方法是使用配对命令将其与您设备配对。
bluetoothctl pair F4:4E:FD:3B:95:A6
注意：请记住将本手册使用的MAC地址 F4:4E:FD:3B:95:A6 替换为您设备的相应 MAC 地址。
如果您要连接的设备具有 GUI 界面，例如智能手机，设备将显示提示，要求您接受连接。系统还会要求您确认PC上的配对。您可以通过在命令行中键入yes来执行此操作。
对于已与主板配对的设备，以后只需使用connect命令即可连接到它们即可，如下所示：
bluetoothctl connect F4:4E:FD:3B:95:A6
- 使用bluetoothctl列出配对设备
您可以通过运行以下命令来查看当前与系统配对的设备：
bluetoothctl paired-devices
您还可以使用以下命令列出计算机蓝牙范围内的设备：
bluetoothctl devices
- 信任配对设备
除了与蓝牙设备配对外，您还可以选择信任某些设备，以便将来轻松连接到它们。
要信任蓝牙设备：
bluetoothctl trust F4:4E:FD:3B:95:A6
您可以通过发出以下命令来取消信任设备：
bluetoothctl untrust F4:4E:FD:3B:95:A6
- 断开蓝牙设备
要取消配对蓝牙设备，请使用删除命令，如下所示：
bluetoothctl remove F4:4E:FD:3B:95:A6
您还可以使用bluetoothctl将设备与系统断开连接：
bluetoothctl disconnect F4:4E:FD:3B:95:A6
如果您希望阻止特定设备连接到您的系统，可以使用阻止命令，后跟该设备的 MAC 地址。
bluetoothctl block F4:4E:FD:3B:95:A6
要取消阻止设备，只需将上述命令中的单词阻止替换为取消阻止即可。
- 使用bluetoothctl的交互模式
bluetoothctl是一个交互式实用程序。我们建议使用交互模式，因为它更快、更容易使用。要进入交互模式，只需运行不带参数的bluetoothctl命令，如下所示：
bluetoothctl
root@T113-Embfly:/embfly_test# bluetoothctl
Agent registered
切换到交互模式后，您可以发出命令，先看看它有什么指令，如下所示:
[bluetooth]# help
Menu main:
Available commands:
-------------------
advertise Advertise Options Submenu
scan Scan Options Submenu
gatt Generic Attribute Submenu

[bluetooth]#
这些指令和非交互模式的时候是一样的。
要退出 bluetoothctl 交互模式，只需在提示符中键入 exit 即可。
使用主板连接蓝牙音箱播放音乐
对蓝牙设备进行配对连接后，还要判断是否正常连接。通常使用l2ping指令来判断，指令执行如下：
root@T113-Embfly:~# l2ping -f -s 512 -c 10 -t 1 F4:4E:FD:3B:95:A6
