What is MQTT?

[@dmbraun745]

So well explained. Went in not knowing what MQTT was, and by the end of the video I had already applied the knowledge to improve automation on the home network.

[@MyJoyInTheAir]

Thanks for a good explanation.

[@ardentdfender4116]

I’m new to learning about MQTT. As a matter of fact only heard about it first time ever yesterday as I work in Industrial Automations Control working on PLC’s and Upgrading PLC’s in the Industrial space as the Automations Control a lot of the processes. With IoT or rather for us in the industrial space IIoT there is a push to get more information out of the Automation Control System for OEM equipment and push it securely into the cloud where data analytics and metrics can be later applied to that massive amount of data. So I watched half a dozen videos on KZbin and you sir have given me the most clearly concise as well easy explained explanation of what MQTT Protocol is as well with the Glass Board example. You just got me as a new subscriber!

kzbin.info/www/bejne/fnOsl6Joq7t0g7s this will help you

[@AliceAcadmey]

amazing, I like such this kind of video, short and useful

[@linacomet]

Thank you guys for the wonderful short videos! Finally I am learning ;)

[@user-ec6sf7vp6w]

great video and very concise

[@spwim]

best explanation so far

[@spwim]

i watched 3 vids

[@stevecross9159]

Thank you good explanation 👍

[@AmmarTheTrainer]

Thank you . You explained it very well...

[@willijd4]

I know this is off-topic but are you writing backwards?

[@devcentral]

We are not THAT talented around here! Check out our behind the scenes video/article on DevCentral that walks through the magic and studio setup. devcentral.f5.com/articles/lightboard-lessons-behind-the-scenes

[@kevinfox2413]

Then his shirt must be custom made backwards

[@FairuzRafique]

lol this question is asked on every single video

[@imsgenexus1758]

Thank you . Good explanation

[@sadanandburud5157]

Nice short Video. But as you said it's PO model. I'm little sceptical, since client knows to whom to send the message. But over here, client doesn't care to whom the message is being sent. Since MQTT is the guy, who know to whom the message to be sent.

[@surfDaddy]

great little lesson package (just like MQTT)!

[@franmcgrath799]

Peter. Nice presentation thank you. FYI The word "Broker" has no "c" in it...sorry to nitpick...overall great job.

[@devcentral]

Thanks for the comment! Yea, some have pointed that out and no worries about the nit-pick! Glad you're paying attention!!

[@ranganathan7713]

Pub/Sub is age-old messaging pattern. What does MQTT brings to it? That's what I would like to know

[@imransuhail82]

Same. Cane here to zed if there is anything different compared to typical message broker systems . Doesnt seem like it

[@m2vlogs498]

They say its optimized for systems that interacts with clients in low bandwidth regions.

[@khomo12]

Nice!

[@sthomaschannel]

So it is built on the IBM MQ Model. Been around for many years. But what does the Telemetry part do, apart from helping to send periodic data? Are the messages persistent? How do they survive lack of connectivity?

[@psilvas]

Hi. thanks for the comment. I found the specific IBM pages for your questions! For the Telemetry part: www.ibm.com/docs/en/ibm-mq/9.1?topic=overview-mq-telemetry For the persistence question - it depends on the quality of service you choose for a message: www.ibm.com/docs/en/ibm-mq/8.0?topic=concepts-message-persistence And about lack of connectivity, A dropped connection is defined by the MQTT client calling the MqttCallback.ConnectionLost method: www.ibm.com/docs/en/ibm-mq/8.0?topic=troubleshooting-resolving-problem-mqtt-client-connection-dropped Hope that helps!!

[@StephenMannUSA]

This is the most succinct and understandable explanation of MQTT that I have seen yet. Thanks. BTW, what technology is behind the whiteboard?

[@devcentral]

Hi Stephen, we did a "behind the scenes" video that covers the magic here: devcentral.f5.com/articles/lightboard-lessons-behind-the-scenes

[@yenlo69]

F5 DevCentral so the polo in reality has a logo flipped :) nicely done

[@breedx2]

b-r-o-k-e-r (no c)

[@psilvas]

You know, I realized after another pointed that out. Total D'oh!

[@airborneworks6103]

Thank you great explanation we are attempting to use this protocol. Can anyone tell me if there are networks of IOT developers here with in the USA that we can post a project to?

[@neogeo8267]

Are you writing backwards, or is the logo on your shirt reversed so the reverse-image looks correct (or something else even more cheeky?)

[@djxearo]

this videos framerate was transferred with MQTT

[@bestmentor9420]

thank u for your video. i am 900th liker :)

[@steeve3386]

Thanks

[@user-zi8jn1go8k]

is his shirt made mirrored left-to-right? I assume he's not writing backwards so the video must be mirrored but then the shirt has to be too...

[@eideticgoone7035]

Edit: I came up with three clues below, but then saw this video referenced in some of the comments below proving it. kzbin.info/www/bejne/i2iokH9qrKiDisU I'm pretty sure you are correct about the custom mirrored logo on his shirt. Here are some clues. The part on his hair is on his right. For most people this is on the left. The button hole flap on his shirt is on his right side. Most all men's shirts have the button hole flap on the left side. Women's are opposite. Second, his wedding ring is on his right ring finger. The convention is wedding finger on left hand. Just to check I googled "Peter Silva F5" and found this YT video where he is being interviewed. You can see he is wearing his wedding ring on his left hand. Look at: kzbin.info/www/bejne/oKLXaoBrjNuEpqc Good call!

[@WereReallyRelayCamping]

its custom for shirt logos to be on the left, with shirt button holes on the left, button holes in this vid suggest its flipped with a reversed logo, which would be cheaper than a custom shirt with flipped button holes...

[@mtronics1wps874]

Turn playback speed to 1.25. sounds more natural believe it or not....

[@larrybergstrom629]

can you do another video that explains MQTT in a LoRaWAN ?

[@joez.145]

Great video but can this guy really write backwards?

[@psilvas]

Here's a look at how we create these and Thanks for the Comment!! kzbin.info/www/bejne/i2iokH9qrKiDisU

[@dstewar]

Is he writing everything backwards? Or how is that working?

[@nikhilmilind3344]

What about latancy in this

[@alsolh]

Does f5 have load balancing solutions for mqtt brokers?

[@psilvas]

Here's how to configure MQTT on BIG-IP: techdocs.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm-iot-administration-13-0-0/1.html

[@underman5110]

we all here because Michael reeves is watching this live

[@reinux]

Replace the MQTT with "the Internet" and you'd have just as informative a video.

[@manuwhat]

Client ASS

[@moukafaslouka4796]

Broker and not Brocker! And it is not "Message Queue", it is "Message Queuing "

[@DevinMoore2]

hi Michael reeves fans

[@briantw]

BROCKER? ROFL

[@chemicallypure]

I can't watch this with this horrible framerate
