使用ESP32-S2的TWAI（CAN）功能，开启WIFI连接路由器会重启的原因？如何解决？

使用esp-idf-v4.3.1开发ESP32-S2的TWAI（CAN）功能，先初始化TWAI，接收数据正常，然后开启WIFI连接路由器，会立即重启。

单独测试TWAI和WIFI功能都是正常的。

先开启WIFI后初始化TWAI会有两种情况：

1、先开启WIFI连接路由器，如果路由器名称密码填写正确，连接成功后，初始化TWAI正常，但是接收一段时间数据后会重启；

2、先开启WIFI连接路由器，如果路由器名称密码填写错误，连接不成功，初始化TWAI会立即重启。



使用idf.py monitor抓到重启时的数据是：
