求教！NodeRED里的Loop节点如何控制启动停止？
最近研究一个设备需要给它逐条循环 发送代码，逐条发送已经用split 节点实现了。然后后面想用 loop节点（node-red-contrib-loop） 来时代码循环发送，没想到出发循环之后无法停止，不知道哪里错了，求高人指点，真心拜谢！！本人不懂代码，研究了好久都没解决，特来求教。前面的部分去掉了，只循环一个字符消息。
不知道这样连接是否正确，我试过其他连接方式都没有循环输出。
loop节点也没有设置，就是默认的。
按照说明文档，当有 break 命令注入时 就会停止，我试过好几种写法仍然无法停止。
注入的break 也进入了循环

请教如何控制loop，或者有没有其他可以控制 开始、暂停的循环方式？
循环用 link 就完了。 neroxps 发表于 2022-5-27 13:19

请教 link 如何控制开始、停止？ csphhing 发表于 2022-5-27 18:06
请教 link 如何控制开始、停止？
自己写 switch 判断咯。 link不会用。。 还是用loop 吧，判断登出是按 msg.command = "break"; 来控制的 loop的循环在第二个输出，上面是输出最后循环结束的状态 loop节点作者详细介绍了使用方法，又关上有视频， 本帖最后由 yjl 于 2024-4-18 16:44 编辑
时隔两年我才开始学习
不得不说，你是个真大佬啊，能以这种奇特的方式完成死循环，我真是想不到！！loop循环第一个输出是循环执行完的输出（相当于循环结束后的操作），第二个输出是循环过程的输出（相当于循环本身要做的事情）
拿for循环举个例子： for i in “AAABBB” :print(i) ，print("end")
loop的第一个输出相当于要执行print("end") ，第二输出相当于要执行 print(i)
你直接把第一个输出延时1秒后又给了loop作为输入，那就相当于每循环一次后又给自己一个新的循环，这就形成了死循环；正确的做法是把第二个输出处理后再给loop作为输入。
另外，关于你说的文档中的break和restart指令，按照文档应该是判断msg的command属性，而不是判断payload属性，所以你在inject中对payload注入break是没有用的
我也试了，给msg添加了command属性并赋值字符串break，并不能终止循环，我也不知道为啥
