Issue use in Corona SDK

[inforaudio]

Hello: Im try to using in Corona SDK and show a a error

loop or previous error loading module 'mqtt.bit' 12:55:47.955 stack traceback: 12:55:47.955 [C]: in function 'require' 12:55:47.955 ?: in function <?:820> 12:55:47.955 (tail call): ? 12:55:47.955 [C]: in function 'require' 12:55:47.955 ?: in function <?:820> 12:55:47.955 (tail call): ? 12:55:47.955 [C]: in function 'require' 12:55:47.955 ?: in function 'require'

do you know why it?

[xHasKx]

Hello, it may be caused by non-standard behavior of require() function in your Corona SDK lua runtime. When executing local bit = require("mqtt.bit") from protocol.lua it's loading module mqtt/bit.lua. Then mqtt/bit.lua detected Lua version as < Lua 5.3 and then executing return require("bit").

And here is non-standard behavior occurs - on standard Lua it should find system-wide installed package named "bit", but your runtime is trying to load the same module mqtt/bit.lua, which is causing a module loading loop error.

You may try a hotfix:

1. rename mqtt/bit.lua file to mqtt/bit_wrapper.lua
2. replace its loading everywhere in other files like protocol.lua in this manner: local bit = require("mqtt.bit_wrapper")

If this will work - please post here and I'll make same change in this repository.

[inforaudio]

if change the name of mqtt/bit.lua by mqtt/bit_wrapper.lua In line 28 of protocol.lua try to charge mqtt/bit_wrapper.lua and the file mqtt/bit_wrapper.lua

if _VERSION == "Lua 5.1" or _VERSION == "Lua 5.2" or type(jit) == "table" then return require("mqtt.bit") else return require("mqtt.bit53") end

To to find mqtt.bit and thow this error

22:01:12.792 module 'mqtt.bit' not found: 22:01:12.792 no field package.preload['mqtt.bit'] 22:01:12.792 no file 'C:\Users\Pablo\AppData\Roaming\Corona Labs\Corona Simulator\Plugins\mqtt\bit.lua' 22:01:12.792 no file 'C:\Users\Pablo\Documents\Corona Projects\mqttluassl\mqtt\bit.lua' 22:01:12.792 no file 'C:\Program Files (x86)\Corona Labs\Corona\Resources\mqtt\bit.lua' .......... 22:01:12.792 (tail call): ? 22:01:12.792 [C]: in function 'require' 22:01:12.792 ?: in function 'require' 22:01:12.792 C:\Users\Pablo\Documents\Corona Projects\mqttluassl\mqtt\protocol.lua:28: in main chunk 22:01:12.792 [C]: in function 'require' 22:01:12.792 ?: in function 'require' 22:01:12.792 C:\Users\Pablo\Documents\Corona Projects\mqttluassl\mqtt\init.lua:30: in main chunk 22:01:12.792 [C]: in function 'require' 22:01:12.792 ?: in function 'require' 22:01:12.792 C:\Users\Pablo\Documents\Corona Projects\mqttluassl\main.lua:11: in main chunk

[inforaudio]

The more logic is that the file mqtt/bit.lua causing a module loading loop error. Would be comment return require("mqtt.bit") in file bit.lua for try to dont charge again..

if _VERSION == "Lua 5.1" or _VERSION == "Lua 5.2" or type(jit) == "table" then --return require("mqtt.bit") else return require("mqtt.bit53") end

But if made it show a error

In bitwrap.lua, if _version is Lua 5.1 require = "bit" ,, but the file bit dont exist?'

What can i do?

[xHasKx]

inforaudio, in version 1.4.3-3 I've fixed the possible module loading loop, but you still need to be installed module LuaBitOp as you are using Lua v5.1 That's clearly listed in Dependencies section in the README.md

[inforaudio]

Ok, so much thanks. I try it and we have runing the simple.lua example.
But we need to connecto by ssl, port 8883. I add the luasec library how we can read in README.. I see that example of how connect in /test/spec/mqqt-client. and we try it, but i have a problem

In main.lua. We use it: local client = mqtt.client{ debug = client_debug, uri = "mqtt.flespi.io", ssl = true, clean = true, auth = {username = "stPwSVV73Eqw5LSv0iMXbc4EguS7JyuZR9lxU5uLxI5tiNM8ToTVqNpu85pFtJv9"}, } for example, and show the next error..

21:44:36.520 ERROR: Runtime error 21:44:36.520 module 'ssl' not found: 21:44:36.520 no field package.preload['ssl'] 21:44:36.520 no file 'C:\Users\Pablo\AppData\Roaming\Corona Labs\Corona Simulator\Plugins\ssl.lua' 21:44:36.520 no file 'C:\Users\Pablo\Desktop\MQQT_PRO\ssl.lua' 21:44:36.520 no file 'C:\Program Files (x86)\Corona Labs\Corona\Resources\ssl.lua' 21:44:36.520 no file '.\ssl.lua' 21:44:36.520 no file 'C:\Program Files (x86)\Corona Labs\Corona\lua\ssl.lua' 21:44:36.520 no file 'C:\Program Files (x86)\Corona Labs\Corona\lua\ssl\init.lua' 21:44:36.520 no file 'C:\Program Files (x86)\Corona Labs\Corona\ssl.lua' 21:44:36.520 no file 'C:\Program Files (x86)\Corona Labs\Corona\ssl\init.lua' 21:44:36.520 no file 'C:\Users\Pablo\AppData\Roaming\Corona Labs\Corona Simulator\Plugins\ssl.dll' 21:44:36.520 no file '.\ssl.dll' 21:44:36.520 no file 'C:\Program Files (x86)\Corona Labs\Corona\Resources\ssl.dll' 21:44:36.520 no file '.\ssl.dll' 21:44:36.520 no file 'C:\Program Files (x86)\Corona Labs\Corona\ssl.dll' 21:44:36.520 no file 'C:\Program Files (x86)\Corona Labs\Corona\loadall.dll' 21:44:36.520 no file 'C:\Users\Pablo\AppData\Roaming\Corona Labs\Corona Simulator\Plugins\ssl.dll' 21:44:36.520 no file '.\ssl.dll' 21:44:36.520 no file 'C:\Program Files (x86)\Corona Labs\Corona\Resources\ssl.dll' 21:44:36.520 no file '.\ssl.dll' 21:44:36.520 no file 'C:\Program Files (x86)\Corona Labs\Corona\ssl.dll' 21:44:36.520 no file 'C:\Program Files (x86)\Corona Labs\Corona\loadall.dll' 21:44:36.520 stack traceback: 21:44:36.520 [C]: in function 'require' 21:44:36.520 ?: in function 'require' 21:44:36.520 C:\Users\Pablo\Desktop\MQQT_PRO\mqtt\luasocket_ssl.lua:6: in main chunk 21:44:36.520 [C]: in function 'require' 21:44:36.520 ?: in function 'require' 21:44:36.520 C:\Users\Pablo\Desktop\MQQT_PRO\mqtt\init.lua:107: in function 'init' 21:44:36.520 C:\Users\Pablo\Desktop\MQQT_PRO\mqtt\init.lua:600: in function 'client' 21:44:36.520 C:\Users\Pablo\Desktop\MQQT_PRO\main.lua:24: in main chunk

What is the problem?? What is the package.preload['ssl']??

We use in main.lua local openssl = require('plugin.openssl') local socket = require('socket') local http = require('socket.http') local ltn12 = require('ltn12') local plugin_luasec_ssl = require('plugin_luasec_ssl') local crypto = require "crypto"

[xHasKx]

If I get it right, Corona SDK has its own module to wrap raw socket into SSL connection - the require('plugin_luasec_ssl') according this: https://github.com/coronalabs/plugins-sample-openssl/blob/master/luasec/main.lua#L54

And my luamqtt module has ability to abstract network connectivity layer from MQTT logic using so called connectors, see here how it works with luasec module: https://github.com/xHasKx/luamqtt/blob/master/mqtt/luasocket_ssl.lua#L21

So again, if I get it right, you just need to replace local ssl = require("ssl") with local ssl = require('plugin_luasec_ssl') in that luasocket_ssl.lua file in your installation and SSL should work.

Please return back here and post if it will work. In that case I may implement such module variation inside my standard luasocket_ssl.lua module.

First Thanks for all your help . Now with this changes, run properly, connect by mqtt server by 8883 port, publish and received message, but we have a problem

When connect to the server MQTT (client:receive_iteration() or client:receive_loop()) block the simulator and it only can received messages, cant made nothing more. We made a code where put a button and print at console the hour each 500 millis.

When connect to server, only wait news messages and dont show hour and the button dont run. If remove while client.connection do -- or just assert(client:receive_loop()) assert(client:receive_iteration()) end Go perfect. And if stop the Mqtt server same, all run perfect (of course we did not receive messages) But when are connect to Mqtt server the simulator block and only waiting for new message

the code is:

local bitLib = require( "plugin.bit" ) local mqtt = require("mqtt.init") local openssl = require('plugin.openssl') local socket = require('socket') local http = require('socket.http') local ltn12 = require('ltn12')

-- create mqtt client local client = mqtt.client{ debug = client_debug, uri = "192.168.0.182", id="APP", ssl = true, clean = true, } print(client)

assert(client:connect()) print("connected")

assert(client:subscribe{ topic = "saludo", qos = 0, }) print("subscribed")

client:on("message", function(msg) print("received message", msg) --client:disconnect() end)

while client.connection do -- or just assert(client:receive_loop()) assert(client:receive_iteration()) end

function mostrar_hora () print (" hora: " .. system.getTimer()/1000) end mostrar_hora_timer =timer.performWithDelay(500, mostrar_hora, -1)

function boton () print (" boton pulsado : hora " .. system.getTimer()/1000)
end

botonauto=display.newText( "Automatico", 183, 200 ,"mifuente.otf", 33) botonauto:setFillColor(0.08,0.31,0.51) botonauto:addEventListener( "touch", boton )

print("done")

What can i do?? how i should connect to server?

[xHasKx]

inforaudio,

That's because of reading and sending to socket is a blocking operation by default. There is a 2 possible solutions here - running luamqtt receive/send loop in separate OS thread, or using non-blocking sockets. 1st seems to be not applicable to Corona SDK and for the second I googled an example to test:

http://web-c2.anscamobile.com/forum/2011/06/06/code-snippet-how-do-non-blocking-multiplexed-raw-socket-transmission

[inforaudio]

Im sorry bu ,try to adapt to use with MQTT but I do not see form. My knowledge does not reach as much So in the comment of this example, some people ask that dont run properly. Is possible?

[xHasKx]

inforaudio, in last version 1.4.6 you may specify correct ssl module name for your Corona SDK environment like this:

local client = mqtt.client{
    uri = ...
    ssl = true,
    ssl_module = "plugin_luasec_ssl",
}

[xHasKx]

inforaudio, according your last issue with blocking - you need to test something like this:

1. set socket to non-blocking mode afther that line: https://github.com/xHasKx/luamqtt/blob/master/mqtt/luasocket_ssl.lua#L33

   conn.sock:settimeout(0)

2. start a timer using your Corona SDK api in a way like this:

   timer.performWithDelay(20, function() assert(client:receive_iteration()) end, 0) -- try to receive every 20 msec

3. do not start receive loop (client:receive_loop()) for the client

So your app will not be blocked when waiting to packets from MQTT broker.

But it's producing another issues:

1. you have to create some logic to re-connect to broker when your connection is lost
2. clients usually have to periodically send PING-packets to the broker ensuring connection is alive

[inforaudio]

Hello: Thanks for your help , but we cant understand what can i do.

We do not know what to look for or what to expect and we do not know the methods or functions of the library. We also do not know why it is blocked waiting for messages etc.. Our knowledge reaches not so much.

we can try to connect check message and disconnect, but we dont want that the client are always connect and disconnect. I think that is no the way

[inforaudio]

actually my code is it..

-- create mqtt client local client = mqtt.client{ debug = client_debug, uri = "158.255.238.138", id="APP", ssl = true, clean = true, ssl_module = "plugin_luasec_ssl", } print(client) assert(client:connect()) print("connected") assert(client:subscribe{ topic = "saludo", qos = 0, }) print("subscrito")

client:on("message", function(msg) print("received message", msg) --client:disconnect() end)

timer.performWithDelay(20, function() assert(client:receive_iteration()) end, 0) -- try to receive every 20 msec

function mostrar_hora () print (" hora: " .. system.getTimer()/1000) end mostrar_hora_timer =timer.performWithDelay(500, mostrar_hora, -1)

[xHasKx]

Try to add client.connection.sock:settimeout(0) just after subscription

[inforaudio]

Thanks for answer, but nothing..

over the last code we add client.connection.sock:settimeout(0) after subscribe..

assert(client:subscribe{ topic = "saludo", qos = 0, }) print("subscrito") client.connection.sock:settimeout(0)

But nothing..

[inforaudio]

Can you made a simple example of how connect and manage MQTT SSL with this library? without block the program?

[xHasKx]

inforaudio, check this for SSL But still - it will not work without blocking irrespective of SSL on or off

If I'll have few free days - I'll try to find a way to adapt luamqtt to non-blocking sockets using some io loop, which may be replaced by Corona SDK timers

inforaudio, in last version 1.4.6 you may specify correct ssl module name for your Corona SDK environment like this:

local client = mqtt.client{
    uri = ...
    ssl = true,
    ssl_module = "plugin_luasec_ssl",
}

[inforaudio]

Thanks so much for your help.

Yes we use ..... local client = mqtt.client{ debug = client_debug, uri = "192.168.0.167", id="APP", ssl = true, clean = true, ssl_module = "plugin_luasec_ssl", }

The conection is correct publish and received message, but the app keep blocked.. Only wait fo recevied message. when connect , only can liberate by a message received with

client:on("message", function(msg) print("received message", msg) client:disconnect() end)

Else keep connect and blocked the app

[xHasKx]

@inforaudio, I've rolled out the new v2.0.0 version of this lib with in-house ioloop implementation. I think now you may use it in your Corona SDK environment.

The main idea of ioloop that it's "processing" created MQTT client in a infinity loop. But it's blocking the OS thread, so you may use the timers provided by Corona SDK to emulate a infinity loop, like this:

local mqtt = require("mqtt")
local ioloop = require("mqtt.ioloop")

-- create and configure MQTT client
local client = mqtt.client{...}
client:on{...}

-- add your MQTT client to ioloop
local loop = ioloop.get()
loop:add(client)

-- and run ioloop iterations in timer instead of infinity loop
timer.performWithDelay(10, function() loop:iteration() end, 0)

Also please note that a lot of argumetns and some methods was changed. For example, now ssl=true should be replaced with secure=true in MQTT client construction arguments. See examples/simple.lua

Please post here a feedback and close issue

[sgetecnology]

non funziona

[xHasKx]

non funziona

A lot of things changed since version 2.0. @sgetecnology , can you please provide more info about what you've tried, what you expected, and what you got?

[sgetecnology]

in the corona simulator sdk everything works, ssl communication ok data exchange with mosquitto server ok, installing the app in android remains black screen not working, what could be the problem? thank you

[xHasKx]

Do you have some logs, tracebacks, error messages? I didn't test luamqtt on the Corona SDK environment on the real devices

[sgetecnology]

there are no error messages, on the simulator everything works, you can't understand. I send you corona project, from main.lua it is called "connection_mqtt_ssl.lua" in the simulator it's ok, I use zeroBrane studio as ide, so if you don't call the tx () function the screen is displayed when you call tx () the screen of the real device is black app locked. thank you

IT WOULD BE EXCEPTIONAL IF YOU COULD USE IT WITH CORONA SDK, YOU CAN DO THE MIRACLE, HELLO AND THANK YOU

[sgetecnology]

can you tell me if you consider my request? thank you

[xHasKx]

Do you have any logging facility when you run your app on a mobile device? At least writing a log file? If yes - place this log file writings in the various places in your code, then run your app on a mobile device. The best way to solve your issue is to debug it on your device.

Do you have any logging facility when you run your app on a mobile device? At least writing a log file? If yes - place this log file writings in the various places in your code, then run your app on a mobile device. The best way to solve your issue is to debug it on your device.
