用耳机麦录音的音频播放时候有哒哒哒的杂音
这个一般是哪的问题？硬件吗？怎么排查test3.wav test2.wav test1.wav

SkrLOU

博主这个一般是哪的问题咋分析啊我这也是录音然后去播放有哒哒哒的干扰杂声

模组是用的sdio接口，板子背面贴了一块8733bs模组已经调通了都正常了

现在把这个8733bs模组拆下来正面贴了8822cs模组原理图上硬件引脚都是一样的同样是sdio接口

dts不用改什么东西现在8822cs模组的蓝牙已经通了 wifi不行这个要修改哪里啊

搞定了搞定了

这是哪的问题啊我看有说去开Three-wire (H5)的支持我这都开了的呀

我现在USB都是通的插U盘也是OK的网口指示灯也亮了网络不行有没有大佬指点一下

就是现在adb shell 进去默认root权限，想编非root版，这个要改哪里啊

@shz18877605430 在 T113跑bluez，bluetoothctl命令行操作的时候，手机能搜索到蓝牙，但是连接的时候一直连接不上中说：

T113跑bluez，bluetoothctl命令行操作的时候，手机能搜索到蓝牙，但是连接的时候一直连接不上，

大致流程如下操作：
/etc/init.d/dbus start
echo 0 > /sys/class/rfkill/rfkill0/state
echo 1 > /sys/class/rfkill/rfkill0/state
rtk_hciattach -n -s 115200 ttyS1 rtk_h5 & 	
hciconfig hci0 up
bluetoothd -C &
bluetoothctl
    ---->power on               //打开电源
    ---->discoverable on     //打开可发现
    ---->menu adv
         ---->name qq123      //设置蓝牙名字：qq123
         ---->back
    ---->advertise on           //广播
然后使用手机端的nrf connect助手搜索蓝牙，然后点击连接，但是连接不上，超时。

各位大佬，支支招！！！

大佬我这个蓝牙都连不上怎么解决啊

@lyphotoes 在飞凌 OK113i-C 全志T113-i开发板 rtl8723du WIFI 功能测试及蓝牙驱动移植中说：

飞凌 OK113i-C 全志T113-i开发板板载一个RTL8723du wifi/蓝牙二合一模块，板子出厂已经移植好了WIFI驱动但是蓝牙驱动没有，所以这篇文章我们主要做蓝牙驱动的移植和功能验证。

./build.sh menuconfig

在Device Drivers > Network device support > Wireless LAN下找到Realtek 8723D USB WiFi选项。
默认是开启的。

至此，wifi连接路由器成功，可以ping 百度验证是否联网成功。

蓝牙功能

首先打印设备上的蓝牙设备

hciconfig -a

输出为空，应该是没有蓝牙驱动。看来出厂并没有带蓝牙驱动，下一步自行移植蓝牙驱动，板上的无线芯片模组使用的是rtl8723du是一款bt4.2和 wifi 2.4G芯片。

蓝牙驱动移植

修改kernel config
修改OK113i-linux-sdk/kernel/linux-5.4/arch/arm/configs/OK113I_linux_defconfig文件添加如下一行

CONFIG_BT_HCIBTUSB_RTLBTUSB=m

修改Kconfig
添加如下：

  config BT_HCIBTUSB_RTLBTUSB
        tristate "Realtek HCI USB driver support"
        depends on USB
        help
          Realtek Bluetooth HCI USB driver.
          This driver is required if you want to use Realtek Bluetooth
          device with USB interface.
          Say Y here to compile support for Bluetooth USB devices into the
          kernel or say M to compile it as module (rtk_btusb).

修改Makefile
在文档最后添加：

obj-$(CONFIG_BT_HCIBTUSB_RTLBTUSB)    := rtk_btusb.o
rtk_btusb-objs                        := rtk_bt.o rtk_misc.o rtk_coex.o

将驱动文件中如下文件复制到内核目录OK113i-linux-sdk/kernel/linux-5.4/drivers/bluetooth下：

rtk_bt.c
rtk_bt.h
rtk_coex.c
rtk_coex.h
rtk_misc.c
rtk_misc.h

编译内核驱动

./build.sh kernel

编译完成后会在OK113i-linux-sdk/out/t113_i/ok113i/longan/dist目录下生成rtk_btusb.ko驱动文件，将该驱动文件和驱动文件对应的固件文件（rtl8723du_fw.bin和rtl8723du_config.bin）放在板子/lib/firmware/下

为了方便查看驱动加载过程报错信息，打开内核打印信息：

echo 8 4 1 7 > /proc/sys/kernel/printk

将编译好的驱动文件和固件文件上传到板卡上，并将估计文件存放在板卡/lib/firmware目录下。

scp out/t113_i/ok113i/longan/dist/rtk_btusb.ko root@192.168.0.105:/home/forlinx/
scp /home/luoyang/Documents/Dev/Bluetooth/V4-8761蓝牙_Linux驱动/20210819_LINUX_BT_DRIVER/rtkbt-firmware/lib/firmware/rtl8723du* root@192.168.0.105:/home/forlinx/
cp rtl8723du_config /lib/firmware/rtl8723du_config.bin
cp rtl8723du_fw /lib/firmware/rtl8723du_fw.bin

加载驱动试试，报错：

insmod rtk_btusb.ko

在rtk_bt.c文件最后一行添加：

MODULE_IMPORT_NS(VFS_internal_I_am_really_a_filesystem_and_am_NOT_a_driver);

重新编译驱动，然后上传并加载试试。

蓝牙工具软件使用

蓝牙驱动安装成功后就可以对蓝牙设备进行配对连接并进行播放音频操作了，此处我们选择通过蓝牙连接家里的智能音箱天猫精灵作为蓝牙音频输出设备，涉及的蓝牙工具软件开发板上出厂移植好了，所以此处省去了移植这些工具软件的步骤。

启动系统蓝牙服务bluetoothd，使其在后台运行

报错了，因为没有提前运行bluealsa这个程序，运行如下：

至此，再进入bluetoothctl 连接天猫精灵试试，首先输入devices命令打印出扫描到的设备信息，然后使用connect xx:xx:xx:xx:xx:xx连接上想要连接的蓝牙设备，连接成功后提示符会变成[连接的设备]样式，具体如下：

蓝牙音频播放
因为此处我们使用alsa-utils工具集中的 aplay 进行音频播放测试，所以仅仅支持PCM和WAV等音频格式，要是想直接播放 mp3 或者 mp4 等格式音频文件需要借助MPD或者FFmpeg等软件。
上一步我们在bluetoothctl中打印扫描并连接了蓝牙音箱，蓝牙音箱的设备地址如下：

[bluetooth]#devices
Device F1:22:33:1A:48:9B F1-22-33-1A-48-9B
Device C4:DE:E2:DF:E8:22 Keep_CC_50200973

Device 84:7C:9B:6D:FF:11 midea_db_2943
Device 10:9E:3A:92:2E:DA �方�糖(80:7A)

根据上面信息我们可以看到天猫精灵方糖的蓝牙设备地址是10:9E:3A:92:2E:DA ，所以我们可以使用如下命令进行音频播放测试：

root@ok113i:/# aplay -D bluealsa:DEV=10:9E:3A:92:2E:DA ./wishforyou.wav

博主，我按这样的步骤去移植RTL8733BU蓝牙一样USB模组的我这扫不到设备是什么原因啊

@yuhudnehao 在 Linux t507 4.9 蓝牙问题中说：

图中可以看出我的所有蓝牙反面的驱动都已经可以了但是就是灭有hci0出现芯片是xr829 wifi已经可以了但是蓝牙加载都没有相关驱动出来
/dev/ttyS1也有出现

有没有大佬有经验帮忙看看啥原因啊

我这用的是RTL8733BU usb接口的 wifi调通了蓝牙不知道怎么整模组厂给了下面的东西不知道有没有用也不知道咋用的
我看官方也没文档教程说蓝牙要咋搞
有没有博主指导指导

博主有没有移过8733BU usbwifi的模组厂商给了驱动文件我按这种方式来没作用编不出来KO文件

SkrLOU

@daizebin 在 DragonSN烧写PN后可以在哪里可以读出来？中说：

@hnjztyx private分区挂载上就可以了

博主这个怎么挂啊我mount不行

SkrLOU

@fanfan 在移植RTL8811驱动编译报错，sw_usb_disable_hcd、script_parser_fetch、sw_usb_enable_hcd函数没找到中说：

博主这个咋解决的啊

SkrLOU

@kunyi 我现在单纯的去编译出wifi_test,blue_test,推到板子里都有问题啊![c8dc1721-08cc-4f42-a5d3-7a368b9bc237-$@(3@C$}}F5(}@3M6FL]V.png](/assets/uploads/files/1711589918564-c8dc1721-08cc-4f42-a5d3-7a368b9bc237-3-c-f-96-5-96-3m6fl-v.png)
这个是为啥啊

SkrLOU

@kunyi 代理给了测试软件我现在是不知道咋搞到固件升级到板子上用的我是想问下有没有搞过这个的别的模块也可以反正都是要厂商提供模块相对应的测试软件来搞是想问下这个过程

SkrLOU

@kunyi 过程代理不给说咋搞我按照官方文档里的那种在SDK支持的那个工具里吧软件加上去 menuconfig选中编不过

SkrLOU

我们用的是AW869AU的模块代理商给了一个测试用的说明和测试软件我看tina官方RF测试文档上没有这个模块的支持这个要怎么用啊有没有大佬帮帮看看

SkrLOU

我按官方的文档里的量产测试使用指南搞的一版，有部分模块没写具体要怎么配置比如麦克风耳机这些，按文档里的wifi配置的内容搞，wifi扫描测试不通过，但我用命令行的方式测板子的是正常的
有没有大佬搞过的啊

有没有大佬有全志适配过的RTL8733BU的驱动
感谢

SkrLOU

H133的内核交叉编译工具链在哪看用的是哪个啊

SkrLOU

连接设备时，遇到不需要输入密码的蓝牙设备如键盘鼠标等不需要输入密码的设备会导致无法连接的问题
这个要怎么解决

耳机跟HDMI不会自动切换，我播视频的时候，都插默认是耳机播，但是都插的话，我把耳机拔了声音不会自动从耳机切到HDMI，都是从耳机出来，然后单插HDMI播，再插耳机也不会从耳机出来，还是HDMI，需要根据实际情况切换，这种要怎么搞啊
