MQTT Client Gateway / Node Controller / OTA

[gohan]

So basically if we want to make ota updates we need to temporarily replace the mqtt gateway with another ethernet gateway, wait for the sensors to reconnect, run updates and restore back the mqtt, correct?

[Samuel235]

@gohan - If MyController is able to push OTA updates over MQTT (which i'm about to test, give me an hour or two) then no. My theory is that because MQTT doesn't connect the controller directly to the gateway then we shouldn't need to shut anything down, only start MyController up and push the updates.

[vikasjee]

@Samuel235 What are your results?

[Samuel235]

@vikasjee - I've upgraded my gateway to MySensorsV2.1 and having some pretty bad results with just powering up. I'm waiting for people with V2.1 MQTT gateways to reply to threads. Do you run with MQTT gateways on V2.1 by any chance?

[maghac]

I am running a v2.1 MQTT Gateway on a NodeMCU (so it connects to the network with wifi) and it works fine.

It's a bit picky with the power supply but I think that's more a hardware than a software issue.

[Samuel235]

@maghac - I'm not sure how that setup works, but are you able to see any sort of serial monitor to debug or anything?

[maghac]

Yes, when I program it with Arduino IDE I use the serial monitor like normal with other boards. Never had any problems with it.

If you go back to an older version, does it work then?

[Samuel235]

@maghac I downgraded my boardDefs last night to 1.6.11 like advised on this forum. I'm about to install arduino IDE 1.6.11 and replace my latest install of Arduino and attempt to use this. What arduino IDE environment do you use, out of curiosity?

[Samuel235]

Exact same behaviour is happening. This is what is being printed to the serial monitor:

I'm not even certain that anything is wrong here. It just keeps reconnecting to the MQTT server, but it is actually working but i'm concerned about why its doing such inside of the serial monitor. I read somewhere that it does a 'touching base' case to keep it alive or something, but i also recall someone saying that was every 15 seconds or so, this is every 8 seconds (about). Do you happen to know what its sending to a MQTT topic 0/255/0/0/18 for, is this standard behaviour or just mine?

[maghac]

Not sure if mine did that, I can check later.

I'm using the latest Arduino IDE (1.8.1 or something like that)

[Samuel235]

@maghac - The same as the one I've been using apart from the last test then. Thanks for confirming that.

If you wouldn't mind checking a serial output on your later, that would be really appreciated.

[maghac]

Type 18 is the heartbeat message type, I think this is the last element in your MQTT topic so it looks fine I think. Can you monitor the MQTT broker and see what messages are passing through it? (e.g if you can see something being sent by the sensors)

[Samuel235]

@maghac - I know the sensors are sending messages, the gateway is responding as it should to them, i was just concerned about the gateway keep connecting itself to the MQTT server, i was a little worried in case there is a feature in Mosquitto broker that declines the connection if it detects any sort of brute force or anything like that.

[Samuel235]

@maghac

On my MQTT server i'm sure enough receiving a message from the gateway every time it says its reconnected in the serial monitor, sending its version number to the server. By the looks of the serial monitor, its actually reconnecting and not just sending a new message to the MQTT topic. I'm confused to why this is doing this, I had just assumed that the heartbeat message is just a re-sending on a message on that topic. Would like to know if this is the normal behaviour of the gateway to keep constantly reconnecting.

[maghac]

Mine doesn't reconnect. Here's the serial monitor on startup:

After this, it's just continously getting data from sensor 227 (my power meter). My mosquitto broker is getting this:

mysensors-out/0/255/0/0/18 2.1.1
mysensors-out/227/1/1/0/17 7160
mysensors-out/227/1/1/0/24 530

mysensors-out/227/1/1/0/18 0.5700
mysensors-out/227/1/1/0/17 7195

etc etc - it's just the one message on startup.

[Samuel235]

@maghac - Right okay. Atleast i now have someone else's to compare too. So, something is pushing it off the network OR it can't hold its connection.

The start is different to mine, that is probably because you're running that on a ESP8266, right?

I have connected to the MQTT server with MQTTFX, which is a MQTT monitoring tool. Not too familiar with it right now but i can't see the server dropping any connections or anything, it almost seems like the gateway is stuck in a loop.

[gohan]

Did you try to swap the mega for an arduino uno? Or swap the w5100 shield? Just to see if there is any difference, so we can exclude any hw issues

[Samuel235]

@gohan - The only thing that be causing this is software as the 1.6 branch works perfectly on this setup with the same sketch but back when it was 1.6 development.

So, if i'm thinking correctly, even if there is a issue between software and hardware, it should be fixable through software, hope this makes sense to anyone other than myself. I don't have an UNO, the only other thing i have is a nano. I'm currently using a W5100 shield, not module, but i do have some modules here, but they were a pain to get working before and hence why i made the switch to the shield.

EDIT: I can confirm that the shield is working properly as i have ran a http test sketch and i'm able to communicate from my web browser to the arduino. So it must be a software issue.

[Samuel235]

Update: I have tried MySensors versions V2.0, V2.1.1 and even the development branch. From what I can work out, V1.6 when it was a development branch got released as V2.0. But that isn't working either, not sure what state it was in before I changed to V2.1.1 as i never monitored the gateway before i reinstalled the new version.

Either way, none are working, they're all giving me the same result. Therefor i'm attempting to find an issue else where on the network other than MySensors. I'm going to try a new MQTT broker, on a different machine. If this gives the same result then its time to troubleshoot my network. Then if that doesn't show anything i think its safe to revert back to looking through my Gateway software.

[Samuel235]

I can confirm that the issues is not MySensors, I've just created a virtual machine running Ubuntu and installed Mosquitto there. Connected the gateway and perfect functionality. Everything is working as intended with a nice silent serial output until a message is sent to the gateway.
