WIFI_BT

开发板使用的wifi_bt模组是 AW-NB197SM new(43438)

1 WIFI&BT配置​

以x2600e_nand_5.10_defconfig为例

1.1 wpa工具配置​

打开IConfigTool工具，选择配置文件

1

若要使⽤wpa 相关应⽤⼯具，那么需要在buildroot中配置上。首选确认当前buildroot的目录和配置文件：

2

xy@vb:~/job/linux/test/build$ cd ../buildroot/buildroot24/   //进入buildroot目录
xy@vb:~/job/linux/test/buildroot/buildroot24$ make menuconfig

3

4

可以看到wpa 相关应⽤⼯具已经添加，需要保存配置

xy@vb:~/job/linux/test/buildroot/buildroot24$ cp .config ../../build/configs/buildroot/buildroot24_xburst2_mini_adb_gcc1210_defconfig

1.2 配置bt&wifi设备驱动​

1.3 配置wifi mmc总线​

1.4 kernel添加蓝牙通信串口uart1​

根据硬件设计，当前蓝牙通信接口为uart1_pb03 。需要在kernel dts文件中打开uart1_pb03的驱动。首先确定当前kernel的编译目录和配置文件：

xy@vb:~/job/linux/test/build$ cat configs/x2600e_nand_5.10_defconfig |grep kernel
APP_kernel_dir=../kernel/kernel
APP_kernel_config=x2600_evb_module_base_linux_sfc_nand_defconfig

进一步确定当前使用的dts文件：

1.5 开机自启wifi,bt​

wifi，bt 固件路径存放在⼯程⽬录下的wireless/bcm/firmware/wifi_bcm/43438_infineon，wireless/bcm/firmware/bt_bcm编译时会复制到⽂件系统 的/lib/firmware/wifi_bcm，/lib/firmware/bt_bcm⽬录.

如果选择开机⾃启，系统启动时会⾃动将固件加载

13

2 编译烧录​

重新编译配置

xy@vb:~/job/linux/test/build$ make x2600e_nand_5.10_defconfig
xy@vb:~/job/linux/test/build$ make

烧录固件, 没烧录过见烧录说明

3 WIFI功能验证​

使用 WiFi 需要设置想要连接 WiFi 的名称及密码,将配置写入文件,启动 WiFi 时运行配置文件即可

# cd /usr/data/                                    //进入/usr/data/目录更改wifi配置文件

# cat wpa_supplicant.conf 

ctrl_interface=/var/run/wpa_supplicant
update_config=1

network={
    ssid="Guest"                                   //需要连接的wifi名称，不要是中文名称
    scan_ssid=1
    psk="ingenic_guest"                            //需要连接的wifi密码
    priority=1 
    }

配置完后重启,默认是开机自启wifi

# ifconfig -a

4 BT功能验证​

查看bt是否启动，如果没有启动，则在/run/blue_bsa/目录下没有相关文件，需要手动启动 bt_enable_bsa.sh脚本

# ls /run/blue_bsa/

ble_local_keys    bt-avk-fifo       bt-daemon-socket

执⾏商家提供的测试命令,这些命令存放在⼯程的 wireless/bcm/bin/xburst2_bsa/app/⽬录下

xy@vb:~/job/linux/test/wireless/bcm/bin/xburst2_bsa/app$ ls
app_ag  app_avk  app_dg  app_hh  app_manager  app_ops  app_tm
app_av  app_ble  app_hd  app_hs  app_opc      app_pan  simple_app

通过adb将测试命令传到⽂件系统的/run/blue_bsa⽬录下，下⾯我⽤app_manager进⾏测试，扫描我的⼿机蓝⽛设备

# ./app_manager 
Bluetooth Application Manager Main menu:            //功能菜单
