【已解决】君正T31ZL/ZX SDK，支持4G模组

[selimily]

感谢，编译以已解决

另外

1）我用了4G模组，把USB虚拟成了网卡，已打通网络【USB网卡已经有IP，可以ping通百度】，如下SDK选哪个合适？
wifi_ble_fs
wifi_fs
wifi_wire_ble_fs
wifi_wire_fs
wire_fs

2）是否有样例支持扫描TUYA app的二维码，获得token，且嵌入IPC_5.x

[起个中文名]

1、选择wire_fs
2、建议使用开源库，例如libzbar。

确认网络是通的-可以ping通百度

扫描涂鸦app-添加设备的二维码生成token
利用token启动程序 ./tuya_ipc_demo -m 3 -p xx -u xx -a xx -r "./" -t "token值”

帮忙看下如上报错，感谢

demo里面tuya_ipc_wired_demo.c，请根据自己的系统情况适配一下。
另外，建议你先去阅读下本板块置顶帖里面的对接文档，可以让你节省很多时间

[selimily]

非常感谢，已解决，demo样例正常

[selimily]

追加一个问题

采用样例将读文件，修改为抓取摄像头的实时流

由于流为30帧每秒，导致占用了资源，无法建立mqtt连接，无法实时显示摄像头的视频流

请问，该如何操作？ 感谢

建议新问题单独发帖。
建立mqtt只需要建立一个tcp连接，并进行若干交互，对系统资源要求不是很高。建议新问题中提供下更详细的线索。
