wifi
重點注意：wifi.cfg文件修改一定要使用vim，使用notepad++或其他文本編輯工具很容易格式不對，導致不能啓動
1、首先拿到wifi模塊廠家的驅動包：
RTL8723BU_WiFi_linux_v5.2.17.1_26947_COEX20180201-6f52.20180307.rar
https://download.csdn.net/download/xiangzi10/10774452 下載頁面
rtl8723du WiFi驅動，移植SDK
https://download.csdn.net/download/xiangzi10/10915017 下載頁面
mstar的簡單說明文檔：
https://download.csdn.net/download/xiangzi10/11162108 下載頁面
2、將driver文件夾下解壓，解壓出來的目錄拷貝至mstar源碼kernel下，vendor\mstar\kernel\linaro\drivers\net\wireless下並更改文件夾名稱爲rtl8723bu，修改makefile.mk
CONFIG_PLATFORM_I386_PC = n
CONFIG_PLATFORM_MSTAR = y
ifeq ($(CONFIG_PLATFORM_MSTAR), y)
EXTRA_CFLAGS += -DCONFIG_CONCURRENT_MODE
EXTRA_CFLAGS += -DCONFIG_IOCTL_CFG80211 -DRTW_USE_CFG80211_STA_EVENT
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN
EXTRA_CFLAGS += -DCONFIG_PLATFORM_MSTAR
EXTRA_CFLAGS += -DCONFIG_PLATFORM_MSTAR_HIGH
ifeq ($(CONFIG_USB_HCI), y)
EXTRA_CFLAGS += -DCONFIG_USE_USB_BUFFER_ALLOC_TX -DCONFIG_FIX_NR_BULKIN_BUFFER
endif
ARCH:=$(R_ARCH)
CROSS_COMPILE:= $(R_CROSS_COMPILE)
KVER:= 3.10.86
KSRC:= $(KERNEL_BUILD_PATH)
MODULE_NAME := 8723bu
endif
修改drivers\net\wireless的makefile.mk，增加
obj-$(CONFIG_RTL8723BU) += rtl8723bu/
修改Kconfig，增加：
source "drivers/net/wireless/rtl8723bu/Kconfig"
make menuconfig
3、編譯kernel，發生編譯錯誤：
*** No rule to make target ` /hal/phydm/phydm.mk
修改rel8723bu文件夾下的makefile.mk：
export TopDIR ?= $(shell pwd)修改爲
export TopDIR ?= $(shell pwd)/drivers/net/wireless/rtl8723bu
編譯成功
4、insmod 8723bu.ko 錯誤
root@almond:/system/lib/modules # insmod 8723bu.ko
[21073.743551] 8723bu: Unknown symbol wiphy_register (err 0)

[21073.798477] 8723bu: Unknown symbol cfg80211_del_sta (err 0)
這個是沒有先安裝cfg80211.ko導致的。
先 insmod cfg80211.ko,再 insmod 8723bu.ko後，
5、使用iw命令手動啓動測試wifi模塊
# ifconfig wlan0 up
#iwlist wlan0 sacn能掃描出所有網絡了，於是我手機設了一個沒有密碼的wifi熱點，用IW去連
#iwconfig wlan0 mode Managed
#iwconfig wlan0 essid "HUAWEI nova"，連上了，但是沒有IP，下面不知道怎麼弄了
#ifconfig wlan0 192.168.34.123 netmask 255.255.255.0
#ifconfig
wlan0 Link encap:Ethernet HWaddr 8C:18:D9:9E:44:3F

以上問題在於沒有IP地址，查看相關文檔，修改如下：其實iw命令已經包含 iwconfig，iwlist等這些命令，iw命令更新
#ifconfig wlan0 up
#ifconfig
#iw wlan0 scan
#iw wlan0 connect RD1 此時沒有ip
#ifconfig wlan0 192.168.1.156 netmask 255.255.255.0設置IP
#busybox iproute add default via 192.168.1.1 添加網關
#ping 192.168.1.1 OK了
#ping 180.97.33.107 （百度IP）也ok了
接下來就是手動調試wpa_supplicant
#wpa_supplicant -d -iwlan0 -Dnl80211 -c/data/misc/wifi/wpa_supplicant.conf -B&
#wpa_cli -p/var/run/wpa_supplicant scan
Using interface 'wlan0'
Failed to connect to non-global ctrl_ifname: wlan0 error: No such file or directory
原因是 wpa_supplicant.conf 裏面設置ctrl_interface=/var/run/wpa_supplicant
但是/var目錄下沒有/var/run/wpa_supplicant
新建一個可以解決此問題
# wpa_cli -p/var/run/wpa_supplicant scan_results
Selected interface 'wlan0'

以上是手動調試用來確認驅動和wpa_supplicant是否正常，以上linux驅動整合OK
修改安卓層，查看android_ref_codes_M_6.x文件夾裏的文件進行安卓整合：
1、device/mstar/XXX 的目錄下device.mk添加：
BOARD_WIFI_VENDOR := realtek
ifeq ($(BOARD_WIFI_VENDOR), realtek)

BOARD_WPA_SUPPLICANT_DRIVER := NL80211

endif
ifeq ($(BOARD_WIFI_VENDOR), realtek)

endif
####rtl8723bu
2、去掉其他地方關於wifi的配置BoardConfig.mk，BoardConfigCommon.mk
3、修改init.xxx.rc
service rtw_fwloader /system/bin/rtw_fwloader
class main
disabled
oneshot

######## Realtek wifi patch ####################
p2p_supplicant wpa_supplicant的service不需要添加，因爲mstar方案已經將此整合到startSupplicant裏面去了
PRODUCT_PROPERTY_OVERRIDES += \
wifi.interface=wlan0
此原文件已有，無需添加
按文檔修改ANDROID_SDK/device/ti/panda/overlay/frameworks/base/core/res/res/values/config.xml
使用mstar原有的supplicant
3、device/msar/xxx的 preinstall\preinstall.mk添加
$(LOCAL_PATH)/modules/8723bu.ko:system/lib/modules/8723bu.ko
4、修改preinstall\wifi\wifi.cfg
=====
wifi_vendor_name=RTL8723BU
order=1
count_vid_pid=1
vid_pid=0x0bda:0xb720
sta=1
softap=1
p2p=1
5、修改device\mstar\common\preinstall\wifi下wifi_load_apdriver.sh，wifi_load_driver.sh，wifi_unload_apdriver.sh，wifi_unload_driver.sh，startSupplicant.sh ，修改device\mstar\common\preinstall\preinstall.mk
6、編譯AN，報錯
make: *** No rule to make target `out/target/product/bennet/obj/STATIC_LIBRARIES/lib_driver_cmd_rtl_intermediates/export_includes', needed by `out/target/product/bennet/obj/EXECUTABLES/hostapd_intermediates/import_includes'. Stop.
7、拷貝wlan到hardware\realtek\wlan
8、再次編譯，無錯誤。升級完成後wifi可用。
藍牙：
藍牙移植包下載：https://download.csdn.net/download/xiangzi10/10774468
1、拷貝驅動文件至kernel/drivers/bluetooth/
修改linaro\drivers\bluetooth\Makefile添加
obj-$(CONFIG_BT_RTKBTUSB) += rtk_btusb.o
修改linaro\drivers\bluetooth\Kconfig添加
config BT_RTKBTUSB
tristate "RTK HCI USB driver"
depends on USB
help
RTK Bluetooth HCI USB driver
執行make menuconfig
編譯生成rtk_btusb.ko
2、device\mstar\common\sepolicy相關文件修改，依據文檔
3、將模塊廠家的包rtkbt整合進hardware\realtek\bt
4、修改device\mstar\xxx\ueventd.mainz.rc
/dev/rtk_btusb 0666 bluetooth net_bt_stack
5、修改init.xxx.rc
######rtk_bt
# bluetooth
# change back to bluetooth from system
chown bluetooth net_bt_stack /data/misc/bluetooth
mkdir /data/misc/bluedroid 0777 bluetooth net_bt_stack

####rtk_bt
6、編譯升級後藍牙可用
移植中問題點：
1、打不開藍牙，lsmod 發現沒有加載rtk_btusb.ko，打印logcat，如下：

解決辦法：
在device.mk文件裏有PRODUCT_PACKAGES += \
libbluedroid \
查找libbluedroid，發現bluetooth.c文件裏有pid，vid數組，添加相應的模塊id，
static struct bt_vid_pid rtk_tables[] =
{
{0x0bda,0x818c},//RTL8761AW bt + 8192EU wifi combo
{0x0bda,0xb761},//RTL8761AUV bt only
{0x0bda,0xb720},//RTL8723BU bt + wifi combo
{0x0bda,0xb72a},//RTL8723BU bt + wifi combo
{0x0bda,0xd723},//RTL8723DU bt + wifi combo
{0x0bda,0xc820},//RTL8821CU bt + wifi combo
};
重新編譯後升級，發現lsmod裏出現rtk_btusb
2、lsmod裏面有rtk_btusb，但是仍然打不開藍牙，logcat如上還是有：
BluetoothServiceJni: No Bluetooth Library found
BluetoothSdpJni: Bluetooth module is not loaded
解決辦法：
rtkbt裏面的要對移植包做些修改，根據mstar的demo來修改。修改完成後測試OK，可以打開藍牙。
3、藍牙聲音發現有聲音變調及聲音變快問題，已解決。
