CB1 android增加USB蓝牙支持
本帖最后由 jiangdou 于 2014-12-29 09:53 编辑USB蓝牙：http://item.taobao.com/item.htm? ... 9&qq-pf-to=pcqq.c2c
配置内核支持Bluetooth，
1.1 make menuconfig
--- Bluetooth subsystem support
[*] L2CAP protocol support
[*] SCO links support
<*> RFCOMM protocol support
[*] RFCOMM TTY support
<*> BNEP protocol support
[*] Multicast filter support
[*] Protocol filter support
<*> HIDP protocol support
Bluetooth device drivers--->
<*> HCI USB driver
2.android层：
2.1加bluetooth权限：在/device/softwinner/crane-common/ProductCommon.mk
frameworks/base/data/etc/android.hardware.bluetooth.xml:system/etc/permissions/android.hardware.bluetooth.xml
在android.hardware.bluetooth.xml：
<permissions>
<feature name="android.hardware.bluetooth" />
</permissions>
2.2加usb host权限
frameworks/base/data/etc/android.hardware.usb.host.xml:system/etc/permissions/android.hardware.usb.host.xml
在android.hardware.usb.host.xml 里写：
<permissions>
<feature name="android.hardware.usb.host" />
</permissions>
2.3 在/device/softwinner/crane-common/tablet_core_hardware.xml：
<feature name="android.hardware.bluetooth" />
<feature name="android.hardware.usb.host" />
3.init.sun4i.rc
# change rfkill permissions for bluetooth power management
chmod 0666 /sys/class/rfkill/rfkill0/state
chmod 0666 /sys/class/rfkill/rfkill0/type
chown bluetooth bluetooth /sys/class/rfkill/rfkill0/state
chown bluetooth bluetooth /sys/class/rfkill/rfkill0/type
write /sys/class/rfkill/rfkill0/state 0
setprop rw.bluetooth.status "0"
4.device\softwinner\apollo-mele\BoardConfig.mk
BOARD_HAVE_BLUETOOTH := true
5. bluetooh name modify ：external\bluetooth\bluez\src\main.c
static void init_defaults(void)
{
/* Default HCId settings */
memset(&main_opts, 0, sizeof(main_opts));
main_opts.mode= MODE_CONNECTABLE;
main_opts.name= g_strdup("BlueZ");//modify to BlueZ -> cubieb1
亲测可以用
