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

@qinlinbin TinaLinux里面的spi-sunxi.c也有问题，我也遇到了，一直以为是我的问题。使用了你的代码，问题解决了。感谢大佬！

@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 [ 4832.222554] rtk_btusb: module uses symbol (kernel_read) from namespace VFS_internal_I_am_really_a_filesystem_and_am_NOT_a_driver, but does not import it.

[ 4832.314387] rtk_btusb: Unknown symbol kernel_read (err -22) insmod: can't insert 'rtk_btusb.ko': Invalid argument

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。

以上信息说明蓝牙驱动加载成功。
此时，再一次查看系统的蓝牙设备信息会打印如下：

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。

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：

[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 34:29:EF:5B:D2:D3 34-29-EF-5B-D2-D3 Device E8:F5:63:87:03:9D Mi Band 3 Device B8:8C:29:87:72:C9 midea Device 04:7F:0E:40:4A:BD BEIJING-EU5 Device CC:B5:D1:FB:45:3A SMI-M14 Device 45:B8:CC:87:53:F8 45-B8-CC-87-53-F8 Device 84:7C:9B:6D:FF:11 midea_db_2943 Device 10:9E:3A:92:2E:DA �方�糖(80:7A) [bluetooth]#connect 10:9E:3A:92:2E:DA ...

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 34:29:EF:5B:D2:D3 34-29-EF-5B-D2-D3 Device E8:F5:63:87:03:9D Mi Band 3 Device B8:8C:29:87:72:C9 midea Device 04:7F:0E:40:4A:BD BEIJING-EU5 Device CC:B5:D1:FB:45:3A SMI-M14 Device 45:B8:CC:87:53:F8 45-B8-CC-87-53-F8 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：

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

@sun_gogogo
我自己来补充一下吧，来自全志客户官网
vinc00:vinc@5830000 {
vinc0_csi_sel = <0>; //parser通道sel
vinc0_mipi_sel = <0>;//mipi通道sel
vinc0_isp_sel = <0>;//isp通道sel，在线模式只能配为0，离线模式可配置为0~3
vinc0_isp_tx_ch = <0>;//配为0即可，a523 isp tx只有一个
vinc0_tdm_rx_sel = <0>;//离线模式需配置为0~3，需要与isp_sel属性相同；在线模式可不配置
vinc0_rear_sensor_sel = <0>;//后摄使用的sensor_sel
vinc0_front_sensor_sel = <0>;//前摄使用的senosr_sel
vinc0_sensor_list = <0>;//是否使用sensor_list功能 0:not_use 1:use
device_id = <0>;//video节点sel，不可修改
work_mode = <0x0>;//在线、离线模式配置,0：在线模式、1：离线模式
status = “okay”;//节点状态，okay：打开 disabled:关闭
};

1.需要多个sensor同时出图，则配置为离线模式；反之，配置为在线模式
2.离线通路配置：
(1). tdm和isp0需要配置相同的工作模式，vipp0和dma0、vipp1和dma1、vipp2和dma2、vipp3和dma3需要配置相同的工作模式(online和offline)，vipp和isp0也需要配置相同的工作模式(online和offline)
(2). 对应关系:tdm对应tdm0节点，isp对应isp00节点，vipp对应scaler00、scaler10、scaler20、scaler30节点，dma对应vinc00、vinc10、vinc20、vinc30节点，vipp节点与dma节点一一对应即：使用vinc00需要打开scaler00，使用vinc01需要打开scaler01
(3). 只有tdm0、isp00、scaler00、scaler10、scaler20、scaler30、vinc00、vinc10、vinc20、vinc30可以配置work_mode，其他节点配置会出错
(4). menuconfig配置：需要打开[*]use isp for time sharing multiples，其余按需选择
3. 在线模式：在线模式只可使用tdm0、isp00、scaler00、scaler10、scaler20、scaler30、vinc00、vinc10、vinc20、vinc30、vinc40、vinc50节点
4. vinc40、vinc50节点只支持在线模式，出的图为sensor原分辨率的图或者经过裁剪过的图，无法对图片进行缩放

按照上面方法内核崩了。也没有动画出现。

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

您好，论坛的那个文章，最后一步要传哪些文件到开发板上？

也在用这个芯片，同求最新的

@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

@jingyan
有测过两块T507互发互收，都是用2M波特率，这样测试又是没有乱码。所以感觉理论上回环也是没有乱码的，跟PC端传输才有乱码。有空我再测一下回环。

@vc915813805 内核和uboot同时配就好了，显示logo要uboot那边就初始化屏幕

@gharibi R128的SDK暂时未开源，可以向你购买开发板的代理或者商家客服获取

@jamesbo T113 Tina SDK、Longan SDK、开发资料下载 https://bbs.aw-ol.com/topic/1247/

0x48状态是没有回复ACK，外设无响应。请检查设备驱动是否正常

您好，编译包放进去了，重新编译烧写固件后，没有反应是什么问题呀？

@honey130602 兄弟你好，能请教你一下我调试cvbs摄像头时只有video4没有video0，请问你们是怎么调试的？

@honey130602 兄弟你好，请问调试cvbs摄像头的时候video4没有video0，你们是怎么做的？

@livpo 太极派 哈哈哈哈哈

博主这个咋解决的啊

@story_xjj 请问解决了吗，我也遇到同样问题
