WiFi与蓝牙源码包发布规范

1. 概述¶

本文档主要介绍蓝牙、Wi-Fi的源码包release操作步骤和注意事项以及常见问题处理方法。

文档中的{vendor}和{product}对应厂商以及平台。

1.1. 读者对象¶

本文档主要适用于以下工程师：

技术支持工程师
软件开发工程师

2. WiFi与蓝牙源码包发布规范¶

在发布版本时，平台会删除driver源码包，并且也跟driver厂家沟通过了，sigmastar通知客户对应的WiFi与蓝牙版本号，客户再跟driver厂家要对应版本号的源码包到对应路径下修改编译即可。

WiFi、Bluetooth支持的器件及对应的driver版本如下表所示：

模组	客户需要跟driver厂家拿的版本号
RTL8723DU	Wifi driver版本：RTL8723DU_WiFi_linux_v5.13.4.1-0-g3240d362a_COEX20200103-3535.20211130.tar(57895).gz需要Realtek提供 Bluetooth版本：20210702_BT_ANDROID_11.0_RTL8723D_COEX_v3b3b.tar.gz需要Realtek提供
SSW101B	Wifi driver版本：sigmastar_wifi.tar.gz 由Sigmastar提供不支持Bluetooth
RTL8723DS	Wifi driver版本 rtl8723ds v5.13.5-43-g163a63d1e.20221027_COEX20211112-4141.tar.gz 需要Realtek提供 Bluetooth版本 20210702_BT_ANDROID_11.0 需要Realtek提供

2.1. RTL8723DU Wi-Fi 源码移植(USB接口)¶

            <instance>default</instance>
        </interface>
    </hal>
</manifest>

2.2.1. 常见问题分析¶

蓝牙打开失败

使用adb shell lsmod检查rtk_btusb.ko驱动是否加载成功
BLE设备回连失败

让设备增加Link Layer Privacy功能或在bt_target.h关闭BLE_PRIVACY_SPT,第二种方法目前不被android允许，需要自行评估风险。

 usb_anchor_empty
 usb_block_urb
 usb_for_each_dev
 usb_lock_device_for_reset
 usb_reset_device
 usb_unlink_urb

5、使用tar zxvf + 压缩包名称对wifi驱动的代码包sigmastar_wifi.tar.gz进行解压，将解压出来的文件夹进行重命名修改为 ssw101b，并放入到以下路径下vendor/sigmastar/Alkaid/kernel/common/drivers/net/wireless/sstar/

在drivers/net/wireless/sstar/Kconfig文件中添加以下代码：（没有就创建一个）

source "drivers/net/wireless/sstar/ssw101b/Kconfig"

在drivers/net/wireless/sstar/Makefile文件中添加以下代码：（没有就创建一个）

obj-$(CONFIG_SSW101B)      += ssw101b/

6、在/external/wpa_supplicant_8/路径下：

将原有的wpa_supplicant_8替换为提供的wpa_supplicant_8

在/frameworks/opt/net/wifi/libwifi_hal/Android.mk文件中以下位置新增libwifi-hal-sstar

...
# Pick a vendor provided HAL implementation library.
# ============================================================
ifeq ($(WIFI_MULTIPLE_VENDOR_HALS), true)
  # vendor HALs are loaded dynamically and not linked here
  LIB_WIFI_HAL :=
else
  LIB_WIFI_HAL ?= libwifi-hal-fallback
  VENDOR_LOCAL_SHARED_LIBRARIES :=
  ifeq ($(BOARD_WLAN_DEVICE), bcmdhd)
    LIB_WIFI_HAL := libwifi-hal-bcm
    VENDOR_LOCAL_SHARED_LIBRARIES := libcrypto
ifneq ($(wildcard vendor/google/libraries/GoogleWifiConfigLib),)
    VENDOR_LOCAL_SHARED_LIBRARIES += \
        google_wifi_firmware_config_version_c_wrapper
endif
  else ifeq ($(BOARD_WLAN_DEVICE), qcwcn)
    LIB_WIFI_HAL := libwifi-hal-qcom
    VENDOR_LOCAL_SHARED_LIBRARIES := libcld80211
...
  else ifeq ($(BOARD_WLAN_DEVICE), sstar)
    # support Sigmastar WIFI HAL
    LIB_WIFI_HAL := libwifi-hal-sstar
...

2.3.1. 常见问题分析¶

Wi-Fi打开失败（STA模式）：

（1）检查驱动是否成功加载

（2）检查wlan0是否创建

（3）检查wpa_supplicant是否正常运行

（4）检查是否存在可执行的wpa_supplicant

（5）检查wpa_supplicant.conf和p2p_supplicant.conf是否存在并且正确

2.4. RTL8723DS Wi-Fi源码移植(SDIO接口)¶

1、使用tar zxvf + 压缩包名称 ，对wifi驱动的代码包WiFi.tar.gz进行解压，将解压出来的文件夹进行重命名修改为rtl8723ds，并放入到以下路径下vendor/sigmastar/Alkaid/kernel/common/drivers/net/wireless

2、在arch/arm64/configs/{product}_android_gki.fragment文件中添加以下代码：

CONFIG_CFG80211=m
CONFIG_RTL8723DS=m

3、在drivers/net/wireless/Kconfig文件中添加以下代码：

source "drivers/net/wireless/rtl8723ds/Kconfig"

4、在drivers/net/wireless/Makefile文件中添加以下代码：

obj-$(CONFIG_RTL8723DS)    += rtl8723ds/

5、在rtl8723ds/Makefile文件中进行修改

将CONFIG_PLATFORM_MSTAR = n修改成 CONFIG_PLATFORM_MSTAR = y
将CONFIG_PLATFORM_I386_PC = y修改成 CONFIG_PLATFORM_I386_PC = n

6、修改kernel dts支持SDIO模式，在arch/arm64/boot/dts/sstar/pioneer5.dtsi

将sdmmc节点中slot-sdio-use = <0>,<0>,<0>改成slot-sdio-use = <1>,<1>,<1>  //修改对应slot为SDIO模式
将sdmmc节点中slot-intcdzs = <1>,<1>,<1>改成slot-sdio-use = <0>,<0>,<0>   //修改对应slot为关闭CDZ检测

HAL层和wpa_supplicant层可以参考RTL8723DU Wi-Fi 源码移植

2.4.1. 常见问题分析¶

Wi-Fi打开失败（STA模式）：

（1）检查驱动是否成功加载(检查模块是否上电GPIO、有没有复用成SDIO模式，dts是否配置成SDIO模式)

（2）检查wlan0是否创建

（3）检查wpa_supplicant是否正常运行

（4）检查是否存在可执行的wpa_supplicant

（5）检查wpa_supplicant.conf和p2p_supplicant.conf是否存在并且正确

service iprenew_bt-pan /system/bin/dhcpcd -n
  class main

  oneshot

5、在vendor/realtek/hardware/bt/rtkbt.mk中添加

# Realtek Bluetooth MAC addr config
PRODUCT_VENDOR_PROPERTIES += \
    ro.bt.bdaddr_path=/vendor/etc/bluetooth/dummy_addr \
    persist.vendor.rtkbt.bdroid_path=default

PRODUCT_COPY_FILES += \
    $(LOCAL_PATH)/dummy_addr:$(TARGET_COPY_OUT_VENDOR)/etc/bluetooth/dummy_addr
PRODUCT_COPY_FILES += \
       $(LOCAL_PATH)/vendor/etc/bluetooth/rtkbt.conf:vendor/etc/bluetooth/rtkbt.conf \
       frameworks/native/data/etc/android.hardware.bluetooth.xml:$(TARGET_COPY_OUT_VENDOR)/etc/permissions/android.hardware.bluetooth.xml \
       frameworks/native/data/etc/android.hardware.bluetooth_le.xml:$(TARGET_COPY_OUT_VENDOR)/etc/permissions/android.hardware.bluetooth_le.xml \
       $(LOCAL_PATH)/vendor/init/hw/init.realtek.bt.rc:$(TARGET_COPY_OUT_VENDOR)/etc/init/hw/init.realtek.bt.rc

6、在vendor/realtek/hardware/bt/rtkbt.mk中注释掉

#ifeq ($(BOARD_HAVE_BLUETOOTH_RTK_TV), true)
#PRODUCT_COPY_FILES += \
#$(LOCAL_PATH)/vendor/usr/keylayout/Vendor_005d_Product_0001.kl:vendor/usr/keylayout/Vendor_005d_Product_0001.kl \
#$(LOCAL_PATH)/vendor/usr/keylayout/Vendor_005d_Product_0002.kl:vendor/usr/keylayout/Vendor_005d_Product_0002.kl
#endif

7、在vendor/realtek/hardware/bt/code/libbt-vendor/src/android.hardware.bluetooth@1.0.realtek.xml中添加

<manifest version="1.0" type="device">
    <hal format="hidl">
        <name>android.hardware.bluetooth</name>
        <transport>hwbinder</transport>
        <version>1.0</version>
        <interface>
            <name>IBluetoothHci</name>
            <instance>default</instance>
        </interface>
    </hal>
</manifest>

8、在vendor/realtek/hardware/bt/vendor/etc/bluetooth/rtkbt.conf中修改

修改BtDeviceNode=?/dev/ttyS1:H5 为BtDeviceNode=?/dev/ttyS5:H5   //FUART对应的串口节点

9、配置vendor/sigmastar/alkaid/kernel/common/dtbo(2381为例pioneer5-ssz028c-s01a-s.dts) FUART GPIO节点配置

 //FUART
        <PAD_SAR_ADC_16          PINMUX_FOR_FUART_MODE_2      MDRV_PUSE_FUART_RX>,
        <PAD_SAR_ADC_17          PINMUX_FOR_FUART_MODE_2      MDRV_PUSE_FUART_TX>,
        <PAD_SAR_ADC_18          PINMUX_FOR_FUART_MODE_2      MDRV_PUSE_FUART_RTS>,
        <PAD_SAR_ADC_19          PINMUX_FOR_FUART_MODE_2      MDRV_PUSE_FUART_CTS>,

10、修改vendor/sigmastar/alkaid/kernel/common/arch/arm64/boot/dts/sstar/pioneer5.dtsi fuart 节点打开流控配置

       fuart: fuart@1F220400 {
            compatible = "sstar,uart";
            reg = <0x1F220400 0x100>, <0x1F220600 0x100>;
            interrupts= <GIC_SPI INT_IRQ_FUART IRQ_TYPE_LEVEL_HIGH>, <GIC_SPI INT_IRQ_URDMA IRQ_TYPE_LEVEL_HIGH>, <GIC_SPI INT_IRQ_FUART_EMPTY IRQ_TYPE_LEVEL_HIGH>;
            dma = <0>;
            sctp_enable = <1>;
            rx_fifo_level = <0>;
            tx_fifo_level = <0>;
            digmux = <0xFF>;
            status = "okay";
            clocks = <&CLK_fuart>;
        };

2.5.1. 常见问题分析¶

蓝牙打开失败
- 检查ttyS5 FUART节点是否能打开
- 检查是否有权限操作节点
- 检查是否有电(需要rfkill驱动参考 rfkill驱动设置)
BLE设备回连失败

让设备增加Link Layer Privacy功能或在bt_target.h关闭BLE_PRIVACY_SPT，第二种方法目前不被android允许，需要自行评估风险。

3. rfkill驱动设置¶

3.1. rfkill说明¶

rfkill-sstar用来控制WiFi/BT power和reset gpio的驱动，通过配置dts来控制gpio

3.2. rfkill配置¶

1、在vendor/sigmastar/alkaid/kernel/common/net/rfkill文件中确认有没有下面文件,没有需要更新

 rfkill-bt.c  rfkill-wlan.c

2、在vendor/sigmastar/alkaid/kernel/common/arch/arm64/boot/dts/sstar/pioneer5.dtsi文件添加蓝牙节点

  bluetooth: bluetooth {
                compatible = "bluetooth-platdata";
                bt_name = "rfkill_bt";
                BT,reset_gpio = <&gpio PAD_SAR_ADC_13 0>;
                BT,wake_gpio = <&gpio PAD_SAR_ADC_13 0>;
                status = "okay";
        };

3、在vendor/sigmastar/alkaid/kernel/common/arch/arm64/boot/dts/sstar/pioneer5.dtsi文件添加wifi节点

  wifi: wifi {
                compatible = "wlan-platdata";
                wlan_name = "wlan-platdata";
                keep_wifi_power_on = "true";
                WIFI,poweren_gpio = <&gpio PAD_SAR_ADC_12 1>;
                WIFI,reset_gpio = <&gpio PAD_SAR_ADC_10 1>;
                status = "okay";
        };

3.2.1. 常见问题分析¶

识别不到WiFi，加载WiFi驱动不成功
- 编译生成的rfkill_sstar.ko需要在kdrv_sdmmc.ko加载之前加载
- dts配置的WiFi GPIO是否跟硬件原理图一致
反复开关蓝牙失败

检查板子是否有生成rfkill type 节点为bluetooth

命令如下:
```
cat /sys/class/rfkill/rfkill0/type
cat /sys/class/rfkill/rfkill1/type
```
