  1. 硬件部分，参考附件！

  2. Kernel Driver部分
    Device Drivers->Network Device Support->Wireless LAN->AP6476

  3. Android部分（以4.4为例）
    2.1
    device/rockchip/rk3288/wifi_bt.mk文件中，修改如下：

BOARD_CONNECTIVITY_VENDOR := Broadcom
BOARD_CONNECTIVITY_MODULE := ap6xxx_gps

2.2
device/rockchip/rksdk/BoardConfig.mk文件中，

# product has GPS or not
BOARD_HAS_GPS := true

2.3
device/rockchip/common/gps/rk30_gps.mk文件，修改如下：

CUR_PATH := device/rockchip/common/gps

ifeq ($(strip $(BLUETOOTH_USE_BPLUS)),true)
PRODUCT_COPY_FILES +=
device/rockchip/common/gps/ap6xxx/gps.default.so:system/lib/hw/gps.default.so
device/rockchip/common/gps/ap6xxx/glgps:system/bin/glgps
device/rockchip/common/gps/ap6xxx/gpslogd:system/bin/gpslogd
device/rockchip/common/gps/ap6xxx/gpsconfig.xml:system/etc/gps/gpsconfig.xml
PRODUCT_COPY_FILES +=
device/common/gps/gps.conf_AS_SUPL:system/etc/gps.conf
endif

2.4
device/rockchip/rksdk/init.rk30board.rc文件中，确保如下设置：

# AP6476 GPS permission
chmod 755 /system/bin/glgps
chown root system /system/bin/glgps
chmod 644 /system/lib/hw/gps.default.so
chown root system /system/lib/hw/gps.default.so
mkdir /data/gps
chmod 770 /data/gps
chown system net_bt_stack /data/gps
mkdir /data/gps/log
chmod 0777 /data/gps/log
chown system net_bt_stack /data/gps/log

…
on property:ro.rk.btchip=broadcom.bplus
start gpsd

service gpsd /system/bin/glgps -c /system/etc/gps/gpsconfig.xml
class main
disabled
user root
group system

重新make，用GPS软件进行测试；
