What is Bluetooth Mesh?

Bluetooth Mesh is a mesh networking standard based on Bluetooth Low Energy (BLE). It allows for many-to-many communications without a central router and with multiple paths, meaning it is resilient if a node fail. Here is a brief overview of Bluetooth Mesh, plus a demo using the Thingy:53.

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.

[@muhammadatifrafique6107]

Very nicely explain dear ....Thanx💝

[@poshpaul55]

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" ☺

[@HeihachiMishimaZaibatsu]

Thanks for the good explanation!

[@GaryExplains]

Glad it was helpful!

[@ShibasisPatnaik]

Gary please add a thanks button

[@prakash_77]

Fascinating thing!

[@dennyfox3139]

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

[@RPG_ash]

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

[@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!

[@samsara2024]

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.

[@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?

[@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.

[@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 😮

[@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.

Arthur 2: On the Rocks

[@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?

[@scotty3114]

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

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.

[@DingoAteMeBaby]

Yes but why this protocol and not IP/Matter over multi modal?

[@robin_saltnes]

Bluetooth mesh is more popular for industrial and professional uses, as it can support thousands of nodes in the same network. You won't see a warehouse using Matter for its lights, but plenty of warehouses and large offices already use Bluetooth mesh.

[@DingoAteMeBaby]

@@robin_saltnes thanks!

[@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.

[@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 :)

[@jorgeeporgee]

what a mesh

[@Svetoslav85]

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

[@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.

[@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

[@Rampart.X]

NSA Mesh 🥴

[@boo9523]

63$?? Hell nah bro..

[@UPsideDOWNworld321]

mesh = LAG

[@kooshazandparsa4237]

Hi thank you for your great work 🤌🏻
