What is Bluetooth Mesh?

[@smaraggi]

I love that google docs template. Used it many times! Never gets old. Practical, simple and elegant.

[@Razor_Burn]

Fantastic video Gary as surprising how overlocked Bluetooth Mesh is and the Thingy 53 is a neat little dev board!

[@prakash_77]

*overlooked, you're welcome.

[@Saturn2888]

It's neat there are so many technologies you can use for whatever your needs are: Z-Wave and Z-Wave Plus, Zigbee, Bluetooth and Bluetooth Mesh, Wi-Fi (which can have access points that wirelessly connect to each other), and Thread. Really cool to have so many choices available. I was always "I have Wi-Fi, so I'm gonna stick with Wi-Fi" until I realized it's super easy for companies to brick your products. Then I started looking at alternatives. I used to think only one technology was worth investing in, and sure, with a Mesh, it's great to have a lot of one type, but today, I get excited to think how free I am to buy any technology I want because I use Home Assistant. I want Wi-Fi mixed with Zigbee and Z-Wave and Bluetooth? I have that!

[@ThorDyrden]

Only loosely related - but another piece of impressive wireless-tech imho is ZigBee. I only got into this home-automation lately after moving to a new location - but you have one central control-center connected to your home-network. And then every device in the "ZigBee-mesh" can act as repeater to extend the reach of the commands... I meanwhile have devices from three different manufacturers working togeather flawlessly... and the coolest thing imho: this wireless-signaling is so energy efficient - I have wall mounted controll-switches, which don't need ANY cable or battery at all. The power I generate when pressing the switch is sufficient to send the command into the ZigBee-mesh 😮

Wow Gary im learning so much from your channel Love all types of tech And the film with Dudley Moore with I.O.L was "Arthur 2 On the Rocks" ☺

[@muhammadatifrafique6107]

Very nicely explain dear ....Thanx💝

[@dennyfox3139]

Sounds like an interesting enhancement of the MQTT publish/subscribe model.

[@smile768]

I remember a student flat advert mentioning IOL, indicating they wanted a flatmate with a sense of humour, and perhaps some film knowledge. I was intrigued. It didn't have many other features other than running water and dubious heating.

[@ithames2753]

Nice! It would be Interesting to try to get existing BLE devices to use this protocol, if possible? Also, what are the advantages of BLE Mesh over ZigBee and Z-Wave? .. perhaps lower power usage?

[@NexGen-3D]

I'm wondering what the benefit is over Zigbee as well, Z-Wave I know is too power hungry and in my experience, is not real great, I find Zigbee far better and battery devices last for a very long time, I have a few BLE mesh devices, and so far, they are slower to respond than Zigbee, but that could just be a controller thing.

[@dekus80]

For BLE chips BLE mesh is just software part, so you can use or not when you write you code for BLE chip. 2$ module, take example source code from chip manufacturer and you have BLE mesh node. My opinion the only advantage of BLE Mesh is that many things have BLE, smartphones for example and you can connect directly to BLE mesh, you don't need any gate. BLE mesh and Zigbee characteristics ~ the same, but Thread is a little better and is a future and is used in new Matter smart home.

Gary please add a thanks button

[@DavidAlsh]

Really cool demo! My first question is "we have known about this method of networking for a while, why don't we deliver mobile internet via a mesh network?" I'm guessing if every phone was a relay, battery life would suffer. Most internet traffic is encrypted, but maybe privacy? how much latency do hops add to the requests? Might try my own demo to experiment with this!

[@Saturn2888]

I didn't know Bluetooth had native meshing. I knew it had the ability to proxy with ESPHome and Home Assistant, but this s some neat tech! How many products use this? I just saw it on Sengled's site, but I have really seen it elsewhere. What tells them to mesh with each other? Like, how do they know they're on the same network?

[@samsaraAI2025]

Thanks for the video! Very cool! Is there any place where we could watch like play list tutorial to learn how to program the BT mesh? which is the smaller and cheaper devide, Thing53 is quite expensive if you want to make a big mesh.

[@HeihachiMishimaZaibatsu]

Thanks for the good explanation!

[@GaryExplains]

Glad it was helpful!

[@sapoty]

Can I get access to a bluetooth battery management system via my phone app called Smart BMS over longer distances than the direct connection?

[@walterpark8824]

Excellent short description. Can my iphone be a nnode in a Bluetooth mesh, or does it use a proprietary or special protocol for its airtags, etc?

[@RPG_ash]

Great video, and we got to see Gary's place too hahhah

[@johndoe9497]

WIll this work to mesh multiple Bluetooth speakers to all synch and play the same source at the same time?

[@fire_stick]

Arthur 2: On the Rocks

[@rmarti5163]

is there a good tutorial for programming and setting this up?

[@prakash_77]

Fascinating thing!

Great tech for your IoT but if I got it right so is this tech also used for those things you put on your keyrings and that also abused to track people. Should be possible to have close track on people by knowing the Bluetooth id on the phone like most dont shut down Bluetooth when not in use. If used for IoT Network, is possible to bridge it to the Wi-Fi Network too?

[@GaryExplains]

Something I didn't cover (as most people find it boring) is that Bluetooth Mesh has built-in security, in fact it can't operate in an "open" mode. It only works with all the built-in security active.

[@MrPmjg]

Not sure what you mean buy Bluetooth id, but I have tried to track my own phone for Home Assistant and it wasn't possible to track using Bluetooth without installing any software on it. The reason it wasn't possible is that the only id that was broadcast was the MAC address and this was a random value

[@michaelthomasross3251]

What security is enabled to secure your network?

[@GaryExplains]

I didn't cover that in the video (as most people find it boring), but Bluetooth Mesh has built-in security, in fact it can't operate in an "open" mode. It only works with all the built-in security active.

[@tonysheerness2427]

The analogy of a string of lights belonging to a string and all turning on when the string is switched on does not do it justice.

[@GaryExplains]

I didn't say string, I said garden lights, true I did pick a photo with strings of lights.

[@Geek_alien]

When will you update your speedtest G?

[@GaryExplains]

Not in the foreseeable future, it wasn't popular.

[@Geek_alien]

@@GaryExplains I don't think that's not popular, atleast you gave them what's accurate. TBH i still thinking what would be the outcome if you test the 8gen2 against A16. Please make a speedtest again :)

[@martijn3151]

This is great. But what would be a low cost low power alternative to do this? I can’t spend an extra 70 USD for every garden light 😉

[@scotty3114]

It was the movie "Arthur ". It was hilarious!

[@Svetoslav85]

We've lived in the Mesh since Jan 2021..

[@rkaag99]

i can only think of two Dudly Moore movies. Arthur and 10. i'm thinking Arthur may have had the IOL

[@alecgrolimond1678]

So it is like the apple button or what ever it is called. Good video Thanks.

[@PwnstarUK]

Is it when my mums so annoyed getting her speaker to work her teeth fall out?

[@GaryExplains]

No.

[@iamseyi4real]

What do you think about quantum computer/processors

[@jorgeeporgee]

what a mesh

[@boo9523]

63$?? Hell nah bro..

[@Rampart.X]

NSA Mesh 🥴

[@UPsideDOWNworld321]

mesh = LAG

[@kooshazandparsa4237]

Hi thank you for your great work 🤌🏻

[@airwebber]

WIll this work to mesh multiple Bluetooth speakers to all synch and play the same source at the same time?
