修改 hciattach.c

在 printf("Device setup complete\n"); 后添加:

close(n);
return 0;

删除:

if (ioctl(fd, HCIUARTSETPROTO, u->proto) < 0) {
perror("Can't set device");
return -1;
}

删除:

/* Restore TTY line discipline */
ld = N_TTY;
if (ioctl(n, TIOCSETD, &ld) < 0) {
perror("Can't restore line discipline");
exit(1);
}

让rtl8723bs 更新固件, 运行命令:

sudo ./rtk_hciattach -n -s 115200 /dev/ttyUSB1 rtk_h5

输出log:

同样的套路用在 AP6210上面很正常。

占坑

晕哥 · 2018-05-05 20:08:11

怎么折腾也不行，不知道哪里不行，
完全按照 AP6210的套路搞的。

实在不行只能用bluez了。

晕哥 · 2018-05-07 09:52:25

因为 RTL8723BS 已经画在板子上了,
一直没办法搞定btstack,
那么只能按照Linux的套路bluez 来搞 BLE了.

晕哥 · 2018-05-07 13:49:00

gatttools 用 AP6201B 和 RTL8723BS 永远都是 connect error: Device or resource busy (16)

晕哥 · 2018-05-07 13:56:00

这个是苹果 mac air, ubuntu14.04LTS 挂载自带的蓝牙设备, 运行gatttool, 一切正常。

晕哥 · 2018-05-07 17:03:14

光这三个文件加起来就有 4M, bluez 太重量级了，只能想办法用轻量级协议栈。

sudo ./rtk_hciattach -n -s 115200 /dev/ttyUSB2 rtk_h5

运行上面这个命令, 初始化 115200，后面提升到 1.5Mbps

晕哥 · 2018-05-08 09:46:48

终于找到了设置波特率到 1.5Mbps的地方, 开始我以为和AP6210B那个套路一样，在命令行参数设定，后来发现根本不是。

跟踪 hciattach_rtk.c rtk_parse_config_file() 函数,
打开这个文件 /lib/firmware/rtl_bt/rtlbt_config

改成 14 C0 52 02 即为 115200 波特率,
即对应代码中的

{0x0252C014, 115200}

用逻辑分析仪观察，全程 115200 了.

晕哥 · 2018-05-08 10:29:51

先初始化RTL8723BS:

sudo ./rtk_hciattach -n -s 115200 /dev/ttyUSB1 rtk_h5

运行btstack测试程序:

晕哥 · 2018-05-08 10:32:41

找到这个页面: https://bluekitchen-gmbh.com/btstack/chipsets/

BCSP
The predecessor of H5. The main difference to H5 is that Even Parity is used for BCSP. To use BCSP with BTstack, you use the H5 transport and can call hci_transport_h5_enable_bcsp_mode

看能不能发现一些端倪。

daydayup 说：

都正确连接了，需要时也会给出的低电平。在内核里处理了协议栈的驱动加载之后，可以使用。
然而，目前最头大的问题是，经常启动之后，对于rtk_hciattach的输出，蓝牙模块是完全不给回应的。

Realtek Bluetooth init uart with init speed:115200, final_speed:115200, type:HCI UART H5

...
Realtek Bluetooth :3-wire sync pattern resend : 40, len: 8
Realtek Bluetooth ERROR: H5 sync timed out

即使对BT_RST引脚手工进行拉低的reset，再去连接，也是不理的。
彻底断电重启也只是偶尔可以回应。一旦回应则蓝牙各种功能都正常。

晕哥 · 2018-05-20 06:20:27

现在是可以使用，有时候rtk_hciattach 发命令rtl8723bs没回应?

pighead · 2018-05-20 11:14:55

晕哥说：

5%的情况下启动后可以完整的使用。95%情况下完全不给回应（这种情况拉低bt reset也无效，只能）

另外，请教一下btstack，用posix-h5的时候，看起来是直接用btstack来操作rtl8723bs的蓝牙UART口了，有对chipset或者port做一些什么必要的修改吗？那这时候应该就不需要rtk_hciattach了？

晕哥 · 2018-05-20 11:31:39

rtk_hciattach 应该只是下载一段配置文件或者程序补丁，
比如里面可以设置通讯波特率等,
btstack跑起来之后就和rtk_hciattach 一点关系都没有了。

pighead · 2018-05-20 11:39:42

读了下源码，发现这个文章讲得比较清晰。 https://blog.csdn.net/zjli321/article/details/52122447

uart接口蓝牙驱动框图

hciattach初始化流程

uart接口蓝牙的fw download及config配置工作也放到了应用层，这些工作都是由hciattach来实现。串口的使用有一个切换的过程，在初始化的时候，由hciattach使用串口，初始化完成后，把串口切换给hci使用，hci负责与串口交互蓝牙数据，中间还经过了h4/h5协议层，驱动层跟移植相关只有h4/h5协议，若h4/h5使用的是内核自带的协议，那驱动层就不需要做任何的工作。只有uart接口的蓝牙才需要hciattach工具，hciattach的作用为配置串口，下载fw及config文件，把串口切换给hci_ldisc使用。

晕哥 · 2018-05-20 12:16:04

不错，这个图确实比较直观。

这个是 wav 文件的头吧, 估计是一个bug.

果然，WAV文件的头就是44字节，，，只是后边的PCM数据都没写入文件，是不是我操作不对哦
是不是没收到数据，本来程序要写一个完成的wav 文件的，是不是因为没有收到数据导致只有头了？
或者 a2dp编码转 wav编码出问题了？

我感觉也像是没收到数据，这块有个PCM的回调函数handle_pcm_data才会调用写wav文件的fwrite。
但最开始的初始化会fopen一个wav文件，估计就是这边只简单的打开了（创建了）一个空wav文件，最后fclose掉了。
其实没有数据写进去，因为没有收到PCM数据。即handle_pcm_data没有被调用。

这怎么解决哦，晕哥

大佬，如何设置3M的通信波特率？修改rtl8723bs_bt的驱动代码么，我看波特率设置数值是从芯片那边读过来的。
Realtek Bluetooth :config baud rate to :4928002, hwflowcontrol:5f, 1

对应的：
{0x04928002, 1500000},

咋改成 3000000 呢？我这边是这样，高码率流的曲子，会出现偶发的沙沙响，正在想办法查。

我搞了一顿下来，我把vlc 搞进文件系统，直接用vlc 播放flac 源文件，也是一样的有沙沙响，看来不是蓝牙的问题了，可能是V3S 内置的CODEC的问题了，奇怪。

那这还咋玩……硬件上有器件要换一下？感觉像是频率引起的。
