Atlas 200外设驱动开发和调试指南_ WiFi 和蓝牙 

调试基于Atlas 200 参考板驱动包进行重构调试，调试方法请参考https://support.huawei.com/enterprise/zh/doc/EDOC1100193743/3db58fa7 

 

1 芯片型号 

    WiFi和蓝牙功能使用芯片RTL8822CE芯片，芯片集成w²fi和蓝牙功能。 

2 固件烧录 

    是否需要烧录固件：否 

3 内核配置 

    是否需要使能内核配置：否 

4 驱动调试 

    驱动下载链接：¯ììÝäǿȍȍg²ì¯ñbȇcÑmȍÃwfingžàȍàìw88 

    编译驱动后，主要需要使用以下几个驱动和固件文件： 

    rtw_core.ko 

    rtw_pci.ko 

    rtw_8822c.ko 

    rtw_8822ce.ko 

    rtw8822c_fw.bin 

    rtw8822c_wow_fw.bin 

    将固件文件rtw8822c_fw.bin和rtw8822c_wow_fw.bin放到路径ȍòbȍfiàmw†àžȍàìw88下。 

    按照顺序插入以下驱动： 

    insmod rtw_core.ko 

    insmod rtw_pci.ko 

    insmod rtw_8822c.ko 

    insmod rtw_8822ce.ko 

    使用dmesg | grep rtw可查看驱动初始化信息。 

    àÑÑìʵš†v²nc²ȝm²n²ǿȍòbȍfiàmw†àžȍàìw88ȅ dmesg | grep rtw 

    [ 11.792086] rtw_8822ce 0000:83:00.0: assign IRQ: got 0

    10.5 测试工具 

    ● WiFi测试 

    WiFi测试工具使用wpa_supplicant，包括二进制工具wpa_passphrase、 

    wpa_supplicant和wpa_cli。 

    wpa_supplicant工具是开源工具，工具的下载和编译请自行搜索。 

    连接w²fi测试 

    使用wpa_passphrase将 w²fi热点名和密码写入配置文件/etc/wpa_supplicant/ 

    wpa_supplicant.conf 

    配置命令：wpa_passphrase "热点名" "密码" > /etc/wpa_supplicant/ 

    wpa_supplicant.conf 

    àÑÑìʵš†v²nc²ȝm²n²ǿȍòbȍfiàmw†àžȍàìw88ȅ wpa_passphrase "nova 7 5G" 

    "1234567890" > /etc/wpa_supplicant/wpa_supplicant.conf 

    àÑÑìʵš†v²nc²ȝm²n²ǿȍòbȍfiàmw†àžȍàìw88ȅ cat /etc/wpa_supplicant/ 

    wpa_supplicant.conf 

    network={ 

    ssid="nova 7 5G" 

    #psk="1234567890" 

    psk=b8dde5b43fd7d205718d130f8a1209b205f4b8d1fcbaaf5135377601de74881d 

    } 

    使用wpa_supplicant连接网络wpa_supplicant -Dnl80211 -iwlp131s0 -c/etc/ 

    wpa_supplicant/wpa_supplicant.conf -B 

    àÑÑìʵš†v²nc²ȝm²n²ǿȍòbȍfiàmw†àžȍàìw88ȅ wpa_supplicant -D nl80211 -i wlp131s0 

    -c /etc/wpa_supplicant/wpa_supplicant.conf -B 

    Successfully initialized wpa_supplicant 

    然后使用dhclient wlp131s0自动获取IP，ping www.baidu.com进行测试。 

    根据wlp131s0自动获取的IP，增加默认路由的配置 

    route add default gw 172.20.10.1

    ● 蓝牙测试 

    蓝牙测试工具使用bluez，需要使用工具bluetoothd和bluetoothctl工具进行蓝牙的配对测试。 

    bluez工具是开源工具，工具的下载和编译请自行搜索。 

    蓝牙测试工具方法如下： 

    启动服务端进程 

    ./bluetoothd & 

    root@davinci-mini:/usr/local/bluez_tools/libexec/bluetooth# ./bluetoothd & 

    [1] 10165 

    执行终端工具，进行蓝牙的搜索、配对和连接测试 

    ./bluetoothctl 

    root@davinci-mini:/usr/local/bluez_tools/bin# ./bluetoothctl
