wifi、bt调试步骤：
1>wifi /bt固件
在任意一个rk sdk里，两个文件目录有固件：

 kernel/drivers/net/wireless/rockchip_wlan/external/rkwifibt/

2>wifi/bt 驱动
驱动包含两部分sdio控制器驱动，wifi设备驱动
a>sdio 控制器驱动

sdio_pwrseq: sdio-pwrseq {compatible = "mmc-pwrseq-simple";clocks = <&rk809 1>;clock-names = "ext_clock";pinctrl-names = "default";pinctrl-0 = <&wifi_enable_h>;/** On the module itself this is one of these (depending* on the actual card populated):* - SDIO_RESET_L_WL_REG_ON* - PDN (power down when low)*/reset-gpios = <&gpio0 RK_PA2 GPIO_ACTIVE_LOW>; /* GPIO3_A4 */};&sdio { //控制器dts，compatible 对应驱动bus-width = <4>;cap-sd-highspeed;cap-sdio-irq;disable-wp;supports-sdio;ignore-pm-notify;keep-power-in-suspend;non-removable;num-slots = <1>;mmc-pwrseq = <&sdio_pwrseq>;sd-uhs-sdr104;status = "okay";
};

b>wifi、bt 设备驱动

         wireless-wlan {compatible = "wlan-platdata";wifi_chip_type = "ap6256";WIFI,host_wake_irq = <&gpio0 RK_PB2 GPIO_ACTIVE_HIGH>;status = "okay";};wireless-bluetooth {compatible = "bluetooth-platdata";clocks = <&rk809 1>;clock-names = "ext_clock";uart_rts_gpios = <&gpio1 RK_PC3 GPIO_ACTIVE_LOW>;pinctrl-names = "default","rts_gpio";pinctrl-0 = <&uart1_rts>;pinctrl-1 = <&uart1_rts_gpio>;BT,reset_gpio = <&gpio2 RK_PB0 GPIO_ACTIVE_HIGH>;BT,wake_gpio = <&gpio0 RK_PA1 GPIO_ACTIVE_HIGH>;BT,wake_host_irq = <&gpio0 RK_PB3 GPIO_ACTIVE_HIGH>;status = "okay";};除此之外，在系统启动的时候，需要加载博通的wifi的设备驱动，kernel目录下，rk自带一个应用c 文件加载wifi、bt
kernel/drivers/net/wireless/rockchip_wlan/rkwifi/bcmdhd/bcmdhd.ko

3>wifi/bt 加载
wifi、bt驱动和固件加载方式，存在两种
第一种：

4>wifi/bt 上层调试工具
wifi :nmcli/iwconfig

方式一：（仅支持WPE 加密方式 /无密码wifi）
iwconfig wlan0 essid "wifi_name"   （仅支持WPE 加密方式 /无密码wifi）
iwconfig waln0 key s:123123123
iwconfig wlan0 ap auto
ifconfig wlan0 192.168.3.100
ping 192.18.3.1
方式二：
打开WIFI  nmcli radio wifi on
关闭WIFI  nmcli radio wifi off
扫描WIFI  nmcli dev wifi rescan
查看扫描列表  nmcli dev wifi list
连接无密码的网络    nmcli dev wifi con wifi_name
连接有密码的网络    nmcli dev wifi con wifi_name password key_num
断开当前连接  nmcli con down wifi_name
重新连接断开的连接   nmcli con up wifi_name
创建wifi热点    nmcli device wifi hotspot ifname wlan0  con-name MyHostspot ssid MyHostspotSSID password test123456789
删除已保存的连接    nmcli con del wifi_name 方式三：
wpa_passphrase wifi_name key >> /etc/wpa_supplicant.conf
wpa_supplicant -i wlan0 -B -c /etc/wpa_supplicant.conf
wpa_supplicant -B -i wlan0 -Dwext -c /etc/wpa_supplicant.conf方式四：
vim /etc/network/interfaces
配置 SSID ,加密方式及密码

bt:bluetoothctl

1.设置蓝牙 up running
hciconfig hci0 down
hciconfig hci0 up
2.扫描设备
hcitool scan
hcitool lescan
3.与设备进行交互通讯
gattool -b MAC -I
connect
primary
characteristics
char-read-hnd
char-write-req
char-read-hnd4.文件发送
a：
vi /etc/dbus-1/system.d/bluetooth.conf
在<allow send_interface="org.freedesktop.DBus.Properties"/> 下面：
<allow own="org.bluez.obex"/>
<allow send_destination="org.bluez.obex"/>
b：
