HC3 QA TCP reconnection issue

[TomBaro 0]

Hi everybody,

 

I'm using the TCP example code on this link

Please login or register to see this link.

 

Testing how reliably the connection is restored between the QA TCP client and an external third party server I found that sometimes Fibaro can't reconnect.

I physically disconnect the third party device by unplugging the RJ45 Ethernet connector, leaving it disconnected for a while and then reconnect it and check what's happening.

 

Sometimes the connection is succesfully restored and when I press a device "turn on" button, it is sent to the third party hardware and everything is fine, response is received.

[08.11.2020] [11:37:36 am] [DEBUG] [QUICKAPP572]: onAction: {"actionName":"turnOn","deviceId":573,"args":[573,"turnOn"]}

[08.11.2020] [11:37:36 am] [DEBUG] [QUICKAPP572]: child 573 channel1 turned on[08.11.2020] [11:37:36 am] [DEBUG] [QUICKAPP572]: command sent FN,ON,1

However other times nothing is sent and neither the success nor the failure callback functions are called

[08.11.2020] [11:33:39 am] [DEBUG] [QUICKAPP572]: onAction: {"args":[573,"turnOn"],"actionName":"turnOn","deviceId":573}

[08.11.2020] [11:33:39 am] [DEBUG] [QUICKAPP572]: child 573 channel1 turned on

and nothing else

 

It looks like Fibaro doesn't even try to send any commands. As if it wasn't aware of the connection. Most interestingly, monitoring the network shows that Fibaro responds to the server's keep alive messages, wich suggests that the low-level TCP socket connection is fine. It looks like the problem is with higher level Fibaro's socket handling. Sometimes the onInit() function is automatically called after a while which sorts out the connection. I just don't want to call onInit() unnecessarily from the QA code especially as I can't reliably detect when it is needed.

 

I've been stuck for a while, tried everything including adding a watchdog timer and using heartbeat messages but I can't really put my finger on anything. Fibaro randomly comes back with nothing, connection error, response error, etc. Unfortunately I can't see any pattern. It seems that the success and error callbacks are called randomly, they don't seem to have much to do with what's really happening.

 

Anybody with an insight? I can't really include any code as I've tried so many different versions and there's no pattern and it's hard to replicate the issue. I'm more after an expert who knows how Fibaro works behind the scenes or somebody who's experienced this and managed to get around it.

 

Thanks.

An automatic call of onInit() is a sign that your QA has crashed. Usually it tries to restart the QA immediately when it crash and then it goes into 1 minute intervals trying to start it again.

So, can it be that your code crashes in a handler for your network logic? Many crashes in async handlers tends to not generate any error messages...

One possible way forward is that you can try to run your code offline to decide if your Lua code has issues using my HC3 emulator 

It has net.TCPSocket() support. There you can step through the code and set breakpoints. If it works there you can really blame Fibaro

hi

 

totaly uncleary what you means. 

what TCP/Ip connection are you talking about

what third party server connection are you talking about... and why HC3 should restore TCP/Ip connection what it not created

Wow, I couldn't have wished for anything better! Thank you. Looks like you've made a tool that makes HC3 QA development more straightforward instead of a trial and error exercise. I'll try it and share the outcome.

There is a thread for that tool - if you post questions there I'm happy to support you to get you going. I would recommend ZeroBrane Studio but I know that @10der use it with VS.

Sorry for being unclear, as I mentioned in my post I use the example code snippet of

to connect to FutureNow units using TCP/IP socket communication. Everything else works fine but I've noticed that the reconnection is not always successful. More exactly it looks like Fibaro thinks it's not succesful even though the low-level reconnection seems fine according to Wireshark.

This is the example code snippet I was referring to. The error() callback fuction in both the QuickAppwaitForResponseFunction() and the QuickApp:connect() functions contains the line that attemps the reconnection "fibaro.setTimeout(5000, function() self:connect() end) -- re-connection attempt (every 5s)"

 

-- Quick App template for handling the TCP device

 

function QuickApp:turnOn()

    self:debug("binary switch turned on")

    self:send("Some command for on\n") -- sending data to the device. In a normal implementation it will be a code with an appropriate command.

    self:updateProperty("value", true)

end

 

function QuickApp:turnOff()

    self:debug("binary switch turned off")

    self:send("Some command for off\n") -- sending data to the device. In a normal implementation it will be a code with an appropriate command.

    self:updateProperty("value", false)

end

 

-- the method for sending data to the device

-- the method can be called from anywhere

function QuickApp:send(strToSend)

    self.sock:write(strToSend, {

        success = function() -- the function that will be triggered when the data is correctly sent

            self:debug("data sent")

        end,

        error = function(err) -- the function that will be triggered in the event of an error in data transmission

            self:debug("error while sending data")

        end

    })

end

 

-- method for reading data from the socket

-- since the method itself has been looped, it should not be called from other locations than QuickApp:connect

function QuickApp:waitForResponseFunction()

    self.sock:read({ -- reading a data package from the socket

        success = function(data)

            self:onDataReceived(data) -- handling of received data

            self:waitForResponseFunction() -- looping of data readout

        end,

        error = function() -- a function that will be called in case of an error when trying to receive data, e.g. disconnecting a socket

            self:debug("response error")

            self.sock:close() -- socket closed

            fibaro.setTimeout(5000, function() self:connect() end) -- re-connection attempt (every 5s)

        end

    })

end

 

-- a method to open a TCP connection.

-- if the connection is successful, the data readout loop will be called QuickApp:waitForResponseFunction()

function QuickApp:connect()

    self.sock:connect(self.ip, self.port, { -- connection to the device with the specified IP and port

            self:debug("connection error")

        end,

    })

end

end

    self.ip = self:getVariable("ip")

    self.port = tonumber(self:getVariable("port"))

So I run this code in Zerobrane on a Mac using the fibaroapiHC3.lua

In a terminal on the same mac I run

...and I get a Hello printed!

Haven't tried the reconnect yet.

 

[jgab 1,953]

So I discovered a small bug in the TCP code. Pushed v0.142

 

It seems like you can't connect a luasocket that has been closed. Can't do connect -> close -> connect

Need to create a new socket.

 

Please login or register to see this code.

Moving the  

   self.sock = net.TCPSocket() -- creation of a TCPSocket instance

to the QuickApp:connect() 

makes the code reconnect after failures - in my simulator. However. it seems to be a luasocket design issue.

I can verify that creating a new TCPSocket works on the HC3 too.

Seems like the socket is wasted after it is closed.

[jgab 1,953]

Actually, I take the back - kind of.

As long as you don't close the socket at error you don't need to create a new socket.

This works - and reconnects

Thanks a lot jgab! Does this mean that the example code I used is in error, or at least not the best way to do things?

 

I've commented out the sock.close() line from both the connect() and the waitForResponseFunction() functions but something is still not right. Maybe there's something else wrong in the code.

 

You really seem to be an expert at Lua and Fibaro, even your profile says so Could you please take a look at the code I've just tried and the log it produced.

 

Here's the code with the irrelevant parts removed. A heartbeat (0x0D) is sent every 10 seconds to which the TCP server in the FutureNow unit responds with an > if the connection is alive. If there is no response three times the connect() function will be called.

Here is the log. In the beginning you can see that I turn a child device on and off. All fine. Then I disconnect the network. No answer to the heartbeat messages so the watchdog counter increases to three which causes the the connect() function to be called. Reconnection is attempted every 5 seconds and of course is unsuccesful as the network is physically disconnected. Then at around 10:06 pm I reconnect the network but as you can see reconnection takes a long time and all kinds of seemingly random things happen before things settle. Normally, without any user interaction you should only see these three lines in the debug window every 10 seconds.

 

watchdog counter = 0

command sent

onDataReceived >

 

When reconnecting I would expect an extra "connected" debug message, but that's all.

 

Calling onInit() which creates a new socket at any point sorts things out but it would be a bit of an overkill and might create a new socket while leaving the previous one open which could result in multiple paralelly open sockets.

Your included code example is badly formatted with a lot of newlines, very difficult to read - can you repost?

I've tried to edit it but it looks fine in the edit window, any idea what to do to make it look better? Edit - done, using an external text editor, sorry about that,

 

Btw I've tried the code in the emulator but got different error messages, I'll have to play with it a bit more.

I've also tried it with HC3 and a TCP server running on my laptop instead of the FutureNow unit and the debug window went totally wild with messages coming so quickly that it was impossble to even read them. It seemed as even if the timers didn't work. The only way I could stop them coming was to enter edit mode on HC3 which automatically runs onInit()

Played with the HC3 emulator again. This is the error I'm receiving.

 

QuickApp crashed: fibaroapiHC3.lua:1170: invalid value (table) at index 2 in table for 'concat'

 

and this is line 1170 in fibaroapiHC3.lua

 

function QuickAppBase:debug(...) fibaro.debug("",table.concat({...})) end -- Should we add _TAG ?

Commenting this line out helped.

Ooops, the emulator has never been used to print/debug a socket... thanks, I have pushed a new version of the emulator v0.145 with some other fixes that was in the pipe too.

Now it should write it out as something like "TCPSocket object: 0x37120580"

 

...so that was not your problem - that was my problem

Your problem is also my problem

 

To be honest I'm not much closer to understanding what's happening. I guess it's something with how HC3 handles threads or sockets or how data is read from a socket.

Tried to start everything from scratch and found that I can't even see received data in the emulator running the code you used to test TCP communication.  The same code receives data fine when run on HC3.

 

Anyway, could you please shed some light on how looping waitforResponseFunction() is supposed to work and how exactly TCPSocket:read(callbacks) works? For example what does it do if there's nothing to read? When exactly are the success and error callback functions called? The same questions for TCPSocket:connect(ip, port, callbacks). The callback functions don't seem to work consistently to me but it's probably my ignorance or the lack of documentation.

Do you think creating and using other loops that call themselves when a fibaro.setTimeout goes off can interfere with the waitforResponseFunction() loop?

This is what I'm getting at the moment, not sure if the response error is a cause or a causation, definitely a cause that causes another delayed reconnection attempt but it's not clear what starts the whole circle. Tried to change the timings so that the reconnection attempts will be delayed differently depending on whether they are triggered by the waitforReponse() or Connect() functions when HC3 thinks something went wrong but I'm still no wiser.

No worries guys. It was a faulty power supply. Changing it sorted all the issues. Always think outside the box!!!

Eventually it turned out it wasn't the power supply but a change I made around the same time. It was commenting out the reconnection line from QuickApp:waitForResponseFunction()

Hi guys,

thank you very much for your contribution which I took as reference for my development. I just wanted to share that in my case the socket had to be properly closed, otherwise, the QA  crashed. If self.sock:close() is not commented out, the QA reconnects without problem. I wrote the code as follows with self.sock = net.TCPSocket() inside the connect() function and it worked for me:

function QuickApp:connect()

    self.sock = net.TCPSocket()

    self.sock:connect(self.ip, self.port, {

        success = function() 

            self:debug("Connected successfully.")

            self:debug("OK Socket is ", self.sock)

        end,

        error = function(err)

            self:debug("Connection error:",err)

            self.sock:close()

            self:debug("Error in Socket", self.sock)

            fibaro.setTimeout(5000, function() self:connect() end)

        end

    })

end


Best regards
