ESP32 C3用smartconfig配网不成功怎么解决？

大家好，最近在用ESP32 C3做项目，用的是IDF 4.3在做smartconfig时发现配网成功率很低，于是用smartconfig的例程直接编译下载同样是成功率很低。基本卡在smartconfig_example: Found channel就走不下去。然后app就报错，app用的是ESPTOUCH v2.0

调试信息如下：

I (616) wifi:set rx active PTI: 0, rx ack PTI: 12, and default PTI: 1

I (616) wifi:mode : sta (7c:df:a1:42:64:04)

I (4766) wifi:ic_enable_sniffer
