【RV1106/RV1103】RV1103增加RTL8723BS

Kernel 部分支持

配置 menuconfig

WiFi 功能支持

Bluetooth 功能支持

正基和海华的模块都使用内核的默认 CONFIG_BT_HCIUART 驱动，而Realtek使用自己的hci uart驱动，源码目录为: external\rkwifibt\realtek\bluetooth_uart_driver ， 且使用ko方式加载，所以使用Realtek时一定要把内核的CONFIG_BT_HCIUART配置去掉！如下图，不要选上！！！

原SDK的Busybox配置

增加rfkill的支持

rkwifibt文件 交叉编译内核驱动和rtk_hciattach程序

交叉编译 hci_uart.ko 内核驱动模块

目录在：rkwifibt/realtek/bluetooth_uart_driver
修改Makefile

MODULE_NAME = hci_uart

ifneq ($(KERNELRELEASE),)
	obj-m :=$(MODULE_NAME).o
	$(MODULE_NAME)-y := hci_ldisc.o hci_h4.o hci_rtk_h5.o rtk_coex.o
	#cc1: all warnings being treated as errors解决办法
	CFLAGS = -Wall -Wpointer-arith -Wno-unused
	KBUILD_CFLAGS += -w
else
	PWD := $(shell pwd)
	KDIR := /home/liefyuan/rv1103/luckfox-pico-main/sysdrv/source/kernel

all:
	$(MAKE) -C $(KDIR) M=$(PWD) modules

clean:
	rm -rf *.o *.mod *.mod.c *.mod.o *.ko *.symvers *.order *.a

编译命令：

将会得到：hci_uart.ko

交叉编译 rtk_hciattach

目录：rkwifibt/realtek/rtk_hciattach

修改Makefile

CFLAGS := -Wall -g
CC := $(CROSS_COMPILE)gcc
all: rtk_hciattach
OBJS := hciattach.o hciattach_rtk.o hciattach_h4.o rtb_fwc.o

rtk_hciattach: $(OBJS)
	$(CC) -o rtk_hciattach $(OBJS)

%.o: %.c
	$(CC) $(CFLAGS) -c $< -o $@

clean:
	rm -f $(OBJS)  rtk_hciattach

tags: FORCE
	ctags -R
	find ./ -name "*.h" -o -name "*.c" -o -name "*.cc" -o -name "*.cpp" > cscope.files

将会得到：rtk_hciattach

在这个目录里面有个文件：rtb_fwc.c 有对固件位置的描述：

#define FIRMWARE_DIRECTORY	"/lib/firmware/rtlbt/"
#define BT_CONFIG_DIRECTORY	"/lib/firmware/rtlbt/"
#define EXTRA_CONFIG_FILE	"/opt/rtk_btconfig.txt"
#define BT_ADDR_FILE		"/opt/bdaddr"
#define BDADDR_STRING_LEN	17

所以需要拷贝BT固件到自己开发板文件系统的：/lib/firmware/rtlbt 目录。

开发板上需要的文件：

• /opt/rtk_btconfig.txt
• /lib/firmware/rtlbt/rtl8723b_config
• /lib/firmware/rtlbt/rtl8723b_fw
• /opt/rtk_hciattach
• /opt/hci_uart.ko

BT 部分

需要一个文件夹：rkwifibt-1.0.0 (我从RV1126的SDK里面找到的)

文件系统部分

需要借助buildroot来构建一些蓝牙相关的软件例如：bluez5
我尝试了手动交叉编译这些软件，卡在了bluez5这里已经花费我20h。而借用Buildroot只花费了2h。

我的Buildroot版本是：Buildroot-2023.02.06
上面的配置出来的文件系统非常干净，看一下（make graph-depends）依赖图

大概只有12MB左右。

蓝牙测试

dbus 安装测试遇到的问题

使用dbus-daemon --system --print-pid --print-address命令来启动dbus后台程序为了和蓝牙通讯。

# dbus-daemon --system --print-pid --print-address
dbus-daemon[469]: Failed to start message bus: Failed to bind socket "/run/dbus/system_bus_socket": No such file or directory
1
2

需要创建目录/run/dbus

# mkdir -p /run/dbus
1

# dbus-daemon --system --print-pid --print-address
unix:path=/run/dbus/system_bus_socket,guid=6973ec2014fa0880afbdcae3000000b1
dbus-daemon[461]: Failed to start message bus: Could not get UID and GID for username "dbus"
1
2
3

需要创建一个用户名叫dbus，密码不需要，我文件系统里面没有adduser命令，所以只能在/etc/passwd文件里面最后添加：

dbus:0:0:0:::
1

然后就可以正常了。如下

# dbus-daemon --system --print-pid --print-address
unix:path=/run/dbus/system_bus_socket,guid=8e19ed4e6e585e498d7c956c0000046a

这样看起来，进入蓝牙命令交互之后，是不正常的。

退出该交互界面的方法是：按下 Ctrl + d 组合键来退出 Bluetoothctl 交互模式

运行：power on相当于打开蓝牙
运行：agent on
查找设备：scan on或者devices查找可配对设备
配对：pair MACaddress(刚刚查找的配对设备的mac地址) 这一步需要在手机确认
连接：connect MACaddress(刚刚查找的配对设备的mac地址)
信任设备：trust MACaddress(刚刚查找的配对设备的mac地址)

使用hcitool来操作

上一节中在bluetoothctl没法操作。找到hcitool来操作：

命令：

# hcitool -help
hcitool - HCI Tool ver 5.65
Usage:
        hcitool [options] <command> [command parameters]
Options:
        --help  Display help
        -i dev  HCI device
Commands:
        dev     Display local devices
        inq     Inquire remote devices
        scan    Scan for remote devices
        name    Get name from remote device
        info    Get information from remote device
        spinq   Start periodic inquiry
        epinq   Exit periodic inquiry
        cmd     Submit arbitrary HCI commands
        con     Display active connections

直到这里，我才知道我其实用手机已经扫出了这个蓝牙！因为不知道为啥设备名没有显示出来！

报错处理

hci0 up不了

在运行

• dbus：dbus-daemon --system --print-pid --print-address
• ko：insmod hci_uart.ko
• 初始化：./rtk_hciattach -n -s 115200 /dev/ttyS5 rtk_h5 &

就可以看到hci0了

# hciconfig hci0 up
Can't init device hci0: Unknown error 132 (22)

电源没有打开导致的
查看有哪些天线开关：

# ls /sys/class/rfkill/
rfkill0  rfkill1  rfkill2

查看你的hci0对应哪个rfkillX

# cat /sys/class/rfkill/rfkill0/uevent
RFKILL_NAME=bt_default
RFKILL_TYPE=bluetooth
RFKILL_STATE=0
# cat /sys/class/rfkill/rfkill1/uevent

如上，rfkill2对应的是hci0，而且状态是关闭的。
打开命令

echo 1 > /sys/class/rfkill/rfkill2/state

如下，打开成功。

# cat /sys/class/rfkill/rfkill2/uevent
RFKILL_NAME=hci0
RFKILL_TYPE=bluetooth
RFKILL_STATE=1

• 打开/关闭/重置hci设备：hciconfig hci0 up/down/reset
• 认证打开/关闭：hciconfig hci0 auth/noauth，直接体现在进行蓝牙连接时，是否输入连接PIN密码，用于PIN配对
• 查看/改变蓝牙主从状态：hciconfig hci0 lm 、hciconfig hci0 lm slave
• 查看/设置蓝牙名称：hciconfig hci0 name 、hciconfig hci0 name Donge
• 开启/关闭广播：hciconfig hci0 leadv/ noleadv
• 查看支持的链路层状态：hciconfig hci0 lestates

不知道解决的：进入bluetoothctl交互后命名没有反应
