This guy's personality actually helps me understand the content a lot better. I zone out within seconds of most videos. I can't believe a actually finished a 40 minute video about bluetooth

Great video, thanks ! TDM = Time Division (not domain) Multiplexing SPP = Serial Port Profile (not Protocol) :)

I'm new to Bluetooth, and this video provided insight into how it works. Once I found the video, I was glued to it, til the end. Thank you for taking the time to make it.. Betsy Brahm

Thanks Pete. Very informative. Keep them coming.

Great high level intro of a messy landscape! Thanks.

Loved this! Thank you for the high level instruction. At least now I have some ideas about what's under the hood for Bluetooth!

Thank you for providing in-depth knowledege of bluetooth classical

Awesome work, thanks Pete!

Excellent video fella! Very informative.

Damnit too many joke attempts per minute for me. :-) :D

I missed you a lot Pete ! 😭

Thanks! Would love to see more in-depth on BLE.

I've never had so much fun learning about bluetooth

Hi, do you have a link for the next episode - "low low energy & smart BT" ?

Great Video. Hoping to see Bluetooth Low Energy video as well.

Really great video - wish I'd found this a few weeks ago. Can you recommend a similar video covering the software aspects of connecting - pairing and services etc. I want to use a phone to send small amounts of data to a Bluetooth device without the device having to agree to the pairing. The user won't have any way to say yes on the device itself or key in 4 digit codes etc. Can this be done? Is there some sort of "Discoverable and will accept data from anyone" mode?

The packet layout you described is already when they are connected. Can you describe the packet during scanning and discovery phase?

skip to 3:19, thanks me later

Hello Pete, As you mentioned you will be explaining about the BLE in the next lecture. But there is no post regarding the BLE. Your videos are very helpful. Please make a video on BLE. Thank you so much.

Good work Pete! This is the best starting point for the people with no knowledge of BT.

Does anyone know where I can find more info on BT Classic, particularly SCO for audio. Looking for anything; modules, coding, general, etc.

Nice content for beginners

Can u explain the ARQN and SEQN bit in a noisy and there is a re-transmit. How does the sender, receiver know about these conditions and decide on re-transmission and move on?!

hello, a shared my bluetooth with an unknown guy who said he needed internet for an emergência. Now I'm afraid he hacked me. What shall I do to clean my mobile, please?

34:40 The HCI takes AT commands directly?

Good background info on bluetooth. However for the next video, you could probably do without the background music which is rather distracting :)

the man in the back is priceless

This was fun... I thought I knew a bunch about BT... I don't

Header is 54 bits. So the 18 bits is replicated three times. Can u explain why this triple replication for the header?

so would a single master be able to slave multiple devices (make my phone play music to multiple speakers )

Does HS have FHSS?

4:30 Yes, the organizaiton is called Bluetooth SIG (It's pronounced sig, one word)

At some point you talk about HS and say it is WIFI. But Bluetooth is not WIFI is it ?? Different antaenas etc ... Or is Bluetooth HS Exactly WIFI ? Then why do they have such different names? Would Bluetooth be actually a Slow WIFI ?

A suggestion...some timing diagrams would be make this presentation cleared.

lenova=lenovo (I think). and you did quote universities. At least there's a trailing quote :)

the moment you realize, that your car cant speak the same BT Profile, that your smartphone has and need to buy a bt adapter for aux to connect your phone....

I don't mind the on-the-fly style

Actually its Lenov'O' :-)

you must be crazy to try to understand how this works :-)

8 bytes of sync but 1 bit of sequence? whaaaa?

I tried it, the Bluetooth nerds caught me out.

good teaching but the rock music became disturbing in understanding yu

Hi Pete! Glad to see you back. I love your vids, but please don't do the side camera thing anymore, leave it to the unboxtherapy guy. Here we do serious stuff!

so much data, that's a little hard to grasp...

"MAYBE THEY'RE NOT REAL MAN" XD

4:40 you're not real man

When are they coming out with RedTooth? Bluetooth is so yesteryear? Or at least a GreenTooth that is environmentally responsible?!

Jeebus, this is terrible. First time I ever watched one of these, and also the last.

This guy is not good, gets distracted from the content

The nonstop distracting jokes and ADHD-like personality of the presenter make the video unwatchable!

Yeah this is plain unacceptable. If you do a video about Bluetooth for a high end channel like SparkFun + include a history section, come on, please take 2 seconds to see the precise data. Doesn't look professional to hesitate. But I am sure the rest of the video kicks Danish Arse
