编译失败
怎么回事啊？乱死了。 编译失败是代码的问题，你检查一下代码，发截图过来看看 三春牛-创客 发表于 2023-8-20 11:03

就是这个

删了数据库就没事了 影东尼一 发表于 2023-8-20 15:24

啊，这么多函数？ 影东尼一 发表于 2023-8-20 15:25
删了数据库就没事了
解决了吗？ 影东尼一 发表于 2023-8-20 15:25
删了数据库就没事了
删除什么数据库？函数还是服务器 影东尼一 发表于 2023-8-20 15:25

我好像发现问题了。你这个初始化只是连接了WiFi和MQTT，tinywebDB还没有初始化呢！ 影东尼一 发表于 2023-8-20 15:24
就是这个
你除了没有初始化TinyWebDB服务器，MQTT也还没有设置账号呢！！！
影东尼一 发表于 2023-8-20 15:25

解决一下初始化问题，看可不可以。 根据报错信息来看，是“数据库”这个函数里面的“更新数据”这个积木的报错，报错信息说的是tinywebdb没有用初始化积木
