【已解决】【TuyaOS SDK】二维码配网，设备已经连网完成，TUYA DNS查询失败

[19926824531]

对于TuyaOS SDK开发模式，TuyaOS 3.9.0版本，tkl已经适配完成，二维码配网执行成功，设备已经连网完成，但是目前好像卡在了TUYA DNS查询这一步，串口log有以下的报错信息，请问这可能是什么原因呢？有空麻烦尽快帮忙看下

1. 获取IP后，设备ping外网是否正常？
2. 请提供完整的设备日志

Answer: 1. 获取IP后，设备ping外网正常（试过ping百度正常） 2. 以下附件是完整log

[Passat]

1. 可以上传日志文件等附件
2. SDK日志信息较少，需要打开DEBUG级别的日志。调用 tuya_ipc_set_log_attr(4,NULL);
3. 二维码信息解析后，是否有调用 tuya_ipc_direct_connect ？用法参考： https://developer.tuya.com/cn/docs/iot- ... 9vbq0c7b4u

log的398行：
[DBG_][TuyaService.c: 69] tuya_wifi_QrScanCallback => tuya_ipc_direct_connect succ!!!

SDK debug级别日志

日志中显示获取的 IP地址为 192.168.29.1 应该是不对的，此地址一般是默认网关IP，设备不太可能通过dhcp分配到这个地址

[19926824531]

初始化为AP模式，ip为192.168.29.1，后续配上网切成STA之后，ip变成了192.168.60.102
这个地方ip应该是符合预期的

[19926824531]

请问在设备dhcp分配ip之前获取的这个ip应该给个什么值呢

[Passat]

目前看上去，应该是TKL层接口适配有问题，tkl_wifi_station_get_status 应该是在获取到真正IP的时候状态才是 6(WSS_GOT_IP)
