- Sat Jul 28, 2018 11:28 am #77456 Hi,

I have my mosquitto server running with authentfication and TLS on.
The server is working well with a windows and android client so i guess the server is fine.

The ESP client does connect but it wont pub or sub. I have enabeled all logs for this matter wich tells me the connection is ok but the pub/sub messages are not received by the server. Im struggeling with this for a wile and im posting here now becouse im stuck. If anyone could look at my code and point me in the right direction, that would be appreciated.

I am using a Lolin board for this with this firmware:
NodeMCU custom build by frightanic.com
branch: master
SSL: true
modules: enduser_setup,file,gpio,http,mdns,mqtt,net,node,tmr,uart,wifi,tls
powered by Lua 5.1.4 on SDK 2.2.1(cfd48f3)

Here is my code existing out 4 files:

Init.lua

Code: Select allconnect = require("connect")
config = require("config")
espmqtt = require("espmqtt")

connect.start()

-- Wait untill we get a ip number
tmr.alarm(1,1000, 1, function()
  if wifi.sta.getip()==nil then
    print("Connecting...")
  else
    print("Connected to wifi as: " .. wifi.sta.getip())
    espmqtt.start()
    tmr.stop(1)
  end
end) 


connect.lua

Code: Select alllocal module = {}

function module.start() 
enduser_setup.start(

  function()
    -- Execute when connected
  end,
  function(err, str)
    print("enduser_setup: Err #" .. err .. ": " .. str)
  end
);

end

return module


config.lua

Code: Select alllocal module = {}

module.SSID = {}
-- MQTT setup
-- IP address and port of MQTT server
module.HOST = "mydomain.com"
module.PORT = 8883
-- TLS connection
module.SECURE = 1
-- MQTT user and password
module.USER = "myuser"
module.PASSWORD = "mypass"
-- MQTT topic
module.ENDPOINT = "thuis"

module.ID = node.chipid()
return module


espmqtt.lua

Code: Select alllocal module = {}

local function mqtt_start()
    -- init mqtt client with logins, keepalive timer 120sec
    m = mqtt.Client(config.ID, 120, config.USER, config.PASSWORD)
    -- on publish message receive event
    m:on("message", function(client, topic, data)
        print(topic .. ":" )
        if data ~= nil then
            print(data)
        end
    end)
    -- for TLS: m:connect("192.168.11.118", secure-port, 1)
    m:connect(config.HOST, config.PORT, config.SECURE, function(client)
        print("connected to MQTT broker")
        -- subscribe topic with qos = 0
        client:subscribe("thuis", 0, function(client) print("subscribe success") end)
        -- publish a message with data = hello, QoS = 0, retain = 0
        client:publish(config.ENDPOINT, "hello", 0, 0, function(client) print("sent") end)
    end,
    function(client, reason)
        print("failed reason: " .. reason)
    end)
   
    --m:close();

end

function module.start()
    mqtt_start()
end

return module
