ESP32C3 smartconfig例程配网失败，设备没反应是怎么回事？

我使用vscode开发，idf版本是4.4.1，做的一个小项目上用到了smartconfig，当时使用的还不是C3，封装上写的是ESP-WROOM-32，一切正常，但我换成C3后，烧写同样的代码，smartconfig运行到“scan down”也就是扫描完成开始接收ESPtouch发送的网络连接信息的时候问题就出现了， 手机端使用ESPtouch点确认发送，设备一点反应没有，代码里没找到问题就想着在跑跑例程看看，结果还是同样的问题，设备似乎接收不到UDP广播包，但换回ESP-WROOM-32就正常。 电脑上也试着抓了一下包，可以抓到UDP包。

串口输出大概如下：到scan done就停住了，用esptouch的app怎么点都没反应
