ESP32C3 smartconfig例程配网失败,设备没反应
Posted: Fri Apr 21, 2023 3:53 am
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
