起因：

客户要用。你就得配。

过程：

首先你需要和供应商拿到这份

RTL8723DU_WiFi_linux_v5.13.4-18-gda9ee5bf0_COEX20200103-3535.20210615.tar

本人是码农，产品经理给的。各种解压不提，本人较土，解压是用rar解压的。

然后你需要准备一份文档：

RealTek wifi 驱动移植说明_V1.1.pdf

这份文档在3128 sdk的rkdoc下面有提供。当然有我这个blog，你还要什么文档？

然后进RTL8723DU_WiFi_linux_v5.13.4-18-gda9ee5bf0_COEX20200103-3535.20210615\WIFI\RTL8723DU_WiFi_linux_v5.13.4-18-gda9ee5bf0_COEX20200103-3535.20210615\driver文件夹，解压下面的一坨tar.gz，重命名其为rtl8723du,将其拷贝到3128源码目录下的kernel/drivers/net/wireless/rockchip_wlan

然后按照rk文档开始改该文件夹下(rtl8723du)的Makefile,

CONFIG_RTL8723D = y

CONFIG_PLATFORM_ANDROID_X86 = n

CONFIG_PLATFORM_ARM_RK3188 = y

找到下面这段

ifeq ($(CONFIG_PLATFORM_ARM_RK3188), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN -DCONFIG_PLATFORM_ANDROID -DCONFIG_PLATFORM_ROCKCHIPS
# default setting for Android 4.1, 4.2, 4.3, 4.4
EXTRA_CFLAGS += -DCONFIG_IOCTL_CFG80211 -DRTW_USE_CFG80211_STA_EVENT
EXTRA_CFLAGS += -DCONFIG_CONCURRENT_MODE
# default setting for Power control
EXTRA_CFLAGS += -DRTW_ENABLE_WIFI_CONTROL_FUNC
ifeq ($(CONFIG_SDIO_HCI), y)
EXTRA_CFLAGS += -DRTW_SUPPORT_PLATFORM_SHUTDOWN
endif
# default setting for Special function
ARCH := arm
#CROSS_COMPILE := /home/android_sdk/Rockchip/Rk3188/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-
#KSRC := /home/android_sdk/Rockchip/Rk3188/kernel
CROSS_COMPILE := /media/lzywork/rk3128_nougat_mid/prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/bin/arm-eabi-
KSRC :=/media/lzywork/rk3128_nougat_mid/kernel
MODULE_NAME := 8723du
endif

改的是KSRC CROSS_COMPILE MODULE_NAME

然后修改

编辑内核选项文件或者用

make menuconfig
打开8723的内核配置

总之最后结果就是kernel/.config 多了一行 CONFIG_RTL8723DU=m

此处斜眼，请看文档去开图形界面配，或者arch/arm/configs/rockchip_defconfig里面加

然后你就在kernel目录下make modules 。 OK 。。ko就出来了。但是。。。wifi此时是开不了的。

有很多原因，其中一个是.ko并不在固件中。本人并不知道kenel是如何把其他模块的把这个.ko拷贝到固件中。反正我开m以后，固件是没有这个.ko的。随便找个地方补上：

#不知道8723ko放哪拷贝先放这里

PRODUCT_COPY_FILES += \

kernel/drivers/net/wireless/rockchip_wlan/rtl8723du/8723du.ko:$(TARGET_COPY_OUT_SYSTEM)/lib/modules/8723du.ko

如果有大佬知道怎么搞定这个，请不吝赐教。不然所有人都不懂。

然后呢，别急，还不行。

然后，编译固件吧！WIFI可以用了。

如果没有这个blog，我估计还要走很多弯路[RK3399 Android7.1.2]新增wifi&bt模块：rtl8822cs驱动以及解决所遇问题_泡芙44的博客-优快云博客_rtl8822cs手册

也可以去这里看

迅为瑞芯微3399开发板Android7-WiFi移植步骤_mucheni的博客-优快云博客

然后呢，开始整蓝牙，蓝牙也没有如上blog那么简单。首先到

RTL8723DU_WiFi_linux_v5.13.4-18-gda9ee5bf0_COEX20200103-3535.20210615\BT\20210702_ANDROID_BT_DRIVER_RTL8723D_COEX_v3b3b\20210702_TV_ANDROID_7.x_RTL8723D_COEX_v3b3b的下面，把

rtkbt整个文件夹拷贝到hardware realtek下面。至于原来的文件夹，请自行压缩备份。

然后修改hardware/realtek/rtkbt/code/bt/audio_a2dp_hw下面的Android.mk改成别的啥我不管。反正不能生成这个会和system下面的有冲突。

然后修改hardware/realtek/rtkbt/code/bt/main里面的Android.mk

LOCAL_MODULE := bluetooth_rtk.default

然后，修改

hardware/realtek/rtkbt/code/bt/btif/src/bluetooth.c文件末尾的

hw_module_t HAL_MODULE_INFO_SYM

.id = BT_HARDWARE_RTK_MODULE_ID,//luke fix BT_HARDWARE_MODULE_ID

再改：

hardware/realtek/rtkbt/code/bt/service/hal/bluetooth_interface.cpp里面的

// Open the Bluetooth adapter.

hw_device_t* device;
