Tuya Developer Forum

我使用的SDK版本是sdk_6.1.1-beta.83，开发方式选择的是SDK独立开发方式。按照文档，使用extract_standalone_sdk.sh脚本提取出来sdk的库文件和头文件之后，在software/sdk_6.1.1-beta.83目录下执行make命令，会生成demo可执行文件。我将demo文件以及修改过pid/uuid/authkey配置的tuya_device_cfg.json拷贝到运行环境的同一个目录下，并期望使用./demo -c ./ -m 2 -t AYD8z6FqmP1xxx 的方式运行demo程序并连接到涂鸦云平台，可是等了一会后，没有在涂鸦智能app上看到对应的设备连接。以下是程序的部分运行日志。

^C[signal_handle, 59] get signal(2) name(demo)

设备是通过有线网络连接到互联网的。

tkl_wifi.c需要适配。例如，日志中调用tkl_wifi_get_ip，没有获取到设备ip

请问，我可以先用有线网络来测试demo连接到涂鸦云的功能吗？

可以的，配网模式设置为PARING_MODE_WIRED。连接模式设置为TUYA_IPC_LINK_WIRE。然后适配tkl_wired.c。
demo运行的命令改为：./output/platform_tuyaos-ipc/firmware/tuyaos_demo_ipc -c ./apps/tuyaos_demo_ipc/ -m 3 -t xxxxxxxxxx

配网模式的设置不需要再改代码了吧？因为在启动程序的时候，会通过-m参数传递该配置。

配网模式的设置不需要再改代码了吧？因为在启动程序的时候，会通过-m参数传递该配置。

可以不改配网模式的代码

问题：修改为有线的连接方式来运行demo程序但是无法连接到涂鸦云并出现段错误的问题

详细描述：
我将连接模式改为TUYA_IPC_LINK_WIRE，并适配了tkl_wired.c中获取gw的接口后，重新编译并使用./output/platform_tuyaos-ipc/firmware/tuyaos_demo_ipc -c ./apps/tuyaos_demo_ipc/ -m 3 -t xxxxxxxxxx的方式去运行demo程序

上面这个问题我找到了，是因为没有正确配置网关和DNS的地址导致的问题，我对这两个问题进行了修正，不会再出现上面的报错了，不过还是连接不上涂鸦云，报错的日志如下：
