NodeMCU TMR-错误的参数＃1到'警报'期望为布尔值

编程问答 2022-08-12

问题描述

连接wifi后，我可以调用一个函数来设置我的mqtt连接。但是由于某些原因，当我应设置我的重新连接计时器时，它会感到恐慌。

alarm的参数正确吗？！

local setupMqtt = function()

  m = mqtt.Client("esp1",10)

  local mqtt_connect = function()
    m:connect("192.168.43.110",1883,false)
  end

  local handle_failure = function()
    tmr.create():alarm(2500,tmr.ALARM_SINGLE,mqtt_connect)
  end

  m:lwt("/lwt","offline",0)

  m:on("connect",function(client)
    print("connected")
    m:publish("/lwt","online",1)
  end)

  m:on("connfail",function(client,reason)
    print("failure",reason)
    handle_failure()
  end)

  m:on("offline",function(client)
    print("offline")
    handle_failure()
  end)

  mqtt_connect()

end

我正在使用3.0.0.0 dev分支，因为master分支中存在mqtt的错误

这正在工作

local M = {}

function M.setup()

  local m = mqtt.Client("esp1",10)

  local mqtt_connect = function()
    print("connect")
    m:connect("192.168.1.100",false)
  end

  local t = tmr.create()
  t:register(10000,tmr.ALARM_SEMI,mqtt_connect)

  m:lwt("/lwt",reason)
    t:start()
  end)

  m:on("offline",function(client)
    print("offline")
    t:start()
  end)

  mqtt_connect()

end

return M

解决方法

这是一个已知的错误，将通过PR #3263进行修复。我们将在接下来的几个小时或几天内将其合并。
