需要Android9-Pie，tested on my Nexus5x with PixelExperience9.0
-
设置蓝牙PID、VID
// remount /system as "rw" # adb shell bullhead:$ su bullhead:# mount -o remount,rw /system // pull file bullhead:# cp /etc/bluetooth/bt_did.conf /sdcard # adb pull /sdcard/bt_did.conf . // modify file @ bt_did.conf - productId = 0x1200 + productId = 0x2009 + vendorId = 0x057E // push file # adb push bt_did.conf /sdcard bullhead:# cp /sdcard/bt_did.conf /etc/bluetooth/ -
安装Xposed
Android9.0可用的Xposed。
因为这个项目会使用Xposed禁用除了Hid-Host之外的所有蓝牙服务，所以若不能安装Xposed框架则需修改编译你的系统源码。源码相关修改将在下节进行说明。
-
NFC功能&蓝牙服务
因为Pro手柄的nfc数据需要362字节的InputReport，而在AOSP9.0-Pie的蓝牙源码中将HID_DEV的Report数据大小设置为了64字节。如果需要实现这一功能，你需要修改编译AOSP9.0-Pie源码。
建议修改device项目，而非直接修改AOSP代码
@ device/lge/bullhead/bluetooth/conf/bt_did.conf - productId = 0x1200 + productId = 0x2009 + vendorId = 0x057E @ device/lge/bullhead/bluetooth/bdroid_buildcfg.h + #define HID_DEV_MTU_SIZE 512 // 362+ is OK @ device/lge/bullhead/aosp_bullhead.mk + PRODUCT_COPY_FILES += device/lge/bullhead/bluetooth/conf/bt_did.conf:system/etc/bluetooth/bt_did.conf // build Android # . build/envsetup.sh # lunch aosp_bullhead-userdebug # mka bacon -j8(也许不需要，需验证)
若之前不能安装Xposed框架，则需要修改如下内容(这会影响你手机蓝牙的正常使用，请谨慎)：
