Like all true professionals, you make it look so easy! Can't wait for part 2!

let me guess its just USB that is missing U

stacksmashing: See you again soon * Five months later... *

It would be interesting to see the results from cheap knock-off cables and other 3rd party cables to see what they spit out and if it is legitimate. The extra stuff in the cable and the communications explains the licensing Apple pushes and the increased costs. It also explains why Apple would not want to go USB-C because they would lose money, data, and control over the cables.

I always kind of knew there was something going on. My "genuine" apple cable would only briefly show a charge symbol before the phone would no longer respond. It seems the "genuine" chip in my cable was "taught the wrong response" hehe. Brilliant video, even a simple user like me can understand, and your graphics/editing are top notch! Another sub for your stack ;)

I always get excited when I see a new stacksmashing upload! Looking forward to the rest of this series

Waiting for part 2 😋

Where’s part 2? :(

part 2 when :(

Excellent instructions/explanations. Your voice clarity,tempo, and video presentation for some reason makes it easier to understand, learn, while also retaining the info. I had to sub and comment with my thanks for your work and expertise for me the layman.

I haven't done much research yet, but I'd be very interested in comparing the advantages and disadvantages of USB-C vs Lighting. Anyway, great video!

Having worked on embedded projects that communicate with iOS devices before, I'm very interested to see where this goes. Some of this I recall from the spec; other parts it seems they don't even share with their MFi partners. I will not be sharing more information, as I don't even remember what I can and can't legally say.

fun fact, iPad Pro gen 1 and 2 use all 16 pins on lightning for usb 3.0 speeds (in conjunction with a usb-c to lightning cable)

Cool =D You've made excellent progress there! Looking forward to part 2 =D

The algorithm just gave me this gem that I didn't know I needed to see. What a great video.

“Part 1” *_dips for 7 months_*

Great video! It's really interesting to learn about the technical details of Apple's Lightning connector and how it works. I appreciate the clear explanations and diagrams, and the various links provided for further exploration. Looking forward to Part 2!

Being a software developer in the automation industry, i love this kind of reverse engineering videos. Looking forward to the next parts ;)

I love your approach to reverse engineer the protocol. Waiting for part 2 :D

Waiting for pt.2 for 6 months now

"in the next video?" what!? fastest 9 mins ever. what an awesome video.

This is great part 2 can’t wait … there are some interesting other projects that might be able to be integrated with that tamarin cable, not very sure what “level” of signal processor / logic analyzer is required. But I have seen some open source logic analyzer on hackaday that use the PIO cores to get up to 24 channels , 16, 8… pretty sure you could pipe the GPIO that’s handling that communication into the other cores and have the ARM cores act like a TCP server to send the data through the USB connected to the PC to double as tamarin / logic analyzer . Very cool project hope there is part 2 , and maybe some Lightning peripherals? Like lightning to usb hdmi hubs ? Get the readings from those ?

You are super good at reverse engineering. Extremely straight forward and informative.

This is really cool! Also, side note, would you do this same analysis on one the old 30 pin cables? It would be really cool to see the differences between the older technology and the newer!

Perfect timing, just before they are forced to use USB-C :D

Wow. As an Apple employee at a Genius Bar, this video brought me a lot. As I love giving my customers some details about their products, this is a lot! Until now, just said that their cable is not only a cable. Now I can explain that there’s a real chip with which the iPhone is talking to. In an other way, can’t understand why we have not tools to determine if a cable is genuine or not.

Didn’t understand a single word, but hey man, nice video, enjoyed it 😄

Having a knowledge like yours just seems like rocket science. Just awesome

This was such a dope video when part 2 gonna drop it’s been 4 months

Been waiting for pt.2 for two months now

awesome man!! eagerly waiting for part 2

Great Video. Already waiting for Part 2 :)

Hey, awesome video, loved all the technical details! On a side note, what kind of logic analyser would you recommend for someone just getting into hardware security? The Salae ones you showed are a little outside my undergrad budget ;) Will an ESP32/Raspberry Pi Pico suffice for most beginner usecases? What if I'm dealing with negative voltage signals? Many thanks for your videos! Got here after LiveOverflow recommended them :)

I need the next video! This seems like a series episode and I want to watch all the episodes. 😂 Nice video, bro. I like to brush up some bits, and this type of video is very pleasant to me.

Algorithm sent me here, and I’m glad! Can’t wait for the rest!

Before watching the video, I thought that embedding the chip in the USB cable was stupid, because it costs more and creates more waste. Now, I'm waiting for the next part.

Would be interesting to see message exchange with some cheap, knockoff cable and see if there is any difference in responses.

Tell me you're german without telling me you're german: Him: "Just talking"

very nice I love the breakout header you made.

I like the USB-C connector, but the fact that there are so many different types of cables that use the USB-C connector creates a confusion that didn’t exist before. Still, it is the most meaningful progress we’ve made towards a uniform standard in a long time.

I understood absolutely none of this but i watched the whole thing

This dude is pretty cool 👌 you have earned a well deserved sub 😁

Omg the part you ask to ChatGPT is just mind blowing

Love the way this guy uses Logic Pro to analyse analogue signal

Congrats to the 150k subcribers! and realy nice video !

I dont understand a single thing. But i look cool in a coffeeshop watching your video 😂.

I wish you would do longer videos instead of these 10-minute parts, thanks for the content though, keep it up. Looking forward to making my own cable.

Please continue! Your work is great!!! When is the second part coming?

Great explanation, thanks so much for all your hard work.

Woah this is amazing. I just came from watching Exploring The simulations video on adding USBC to airpods. This is amazing to see

Waiting for the next part of video

you remind me of Ben Eater, not comparing efforts here, great video. subbed.

You should try teaching profession! Your simplicity in presentation and effective communication makes it easy to understand and learn.

I have no interest in this space but LOVED this vid because it as so clear and well produced.

When is part 2?

would love a second part if you have time :D

Looking forward to part two!

WOW!!!! This is such a unique video! Never seen something like this before in my feed.

I like the 1:03 version of the lightning cable.

I heard Apple recently updated the firmware on their cables somehow. I hope this series helps me understand that.

Part 2???

fascinating. Neat how you can figure out so much from so little

Amazing video! When where is part 2?!!?

Awesome detailed video now I want to see Type c power delivery and other protocols as well from you.

Can you please talk about the lighning earphones in the process ? great video by the way

i want the next video NOWWWW

Great video - lots of information and well paced. I'm looking forward to part 2!

Wow, nice one. For how long did this channel exist? Subscribed.

This video got me all charged up. Positively electrifying.

Wow thats amazing! Looking very forward to the next part

Thank you for your very detailed technical sharing, why can't I find the second part, thank you.

Awesome video. Loved every bit of it (pun intended).

That was the first time I've actually seen chatgpt being used, and it wasn't for a joke it was for actual information??? That just blew my mind

Guess I have to subscribe to stay tuned!! Also what analyzer do you use?!?!

I am firmly convinced that the German people are some of the smartest people in the world. The video was amazing! Thank you for sharing your knowledge.

Great work! Can't wait for part 2!

I cannot believe you asked chat gpt and it found an answer within seconds… it’s truly revolutionary

My mind is blown. This video (these videos) are awesome. Thank you so much for sharing your knowledge.

I'm curious to see why apple never upgraded lightning to support USB3.0. From what I can see Lightning has 2 differential lanes and Power and that could carry a USB3 signal. I wonder if theres any other limitation.

this is so interesting wow! im now very curious about a few things tho. 1- How do splitters work? for example i have a very cheap aliexpress splitter that basically lets me plug in both charging cable and lightning earpods on my iphone at once, im guessing this thing is 100% passive but i have no ide and im not about to destroy it rn tbh. but if its passibe how can it communicate with both things at once? and if active, how does it get to split these two things? 2- does the cable reply to the device which charging capabilities it has? like if it can do fast charging or not, or is that linked to the modle number or name itself? 3- does the cable also talk to the charger it connects to? like does the apple PSU get any information about the lightning cable or device? apart from power delivery on fast chargers that is, especially curious on the old usb-a 5w and 10w ones and 4- how do fake cables work then? ive had bad luck getting some knockoff ones bc they would charge very very slowly and im thinking if it might be bc the controller was answering stuff wrong and the iphone has some sort of anti-illegitimate mehcanism or something or if it just replied as if it was the slowest charging cable that exists, i really hope youll check this stuff at some point plz! btw for reference this is the splitter i have (different store same thing tbh, not great bc it requires regular cleaning for it to work, also if u dont have experienc with aliexpress choose the aliexpress saver shipping unless its wayy too expensive for u bc at least in spain that option takes 2 weeks but the caniao expedited economy aka tghe default one for this takes months) www.aliexpress.com/item/1005004576959652.html

absolutely fascinating, can't wait for more videos!

Thank you for yet another fantastic video!

Take this subscription, you deserve it. Quality content.

Eagerly waiting for part 2!

amazing video, cant wait part for other parts

Hey, I love this video, cant wait till part 2

This was honestly really interesting to watch

Amazing video, waiting for part 2!

Super interesting! looking forward to the rest of the series. Also, I didn't know you were German :)

So the serial number for each cable is unique? I can basically smell information gathering from this. Got a new cable from apple store nearby - they know where you have been, even if you left your phone home and paid with cash. Forgot your cable home, battery got low, friend passed you his cable - now apple knows that you connected with this person and contacted physically, even if you was on airplane mode. There is so many scenarios!

gib part2 today pls. thks

im sold, new sub over here, im waiting for part 2

Can't wait to see the next video!!!

Great to see you back on the scene. Superb content delivery. Are you planning on working on a possible jailbreak?

How much variance is there from USB just enough to be proprietary?

Great explanation and neat graphics!

Will you be exploring how the lightning dongles such as 3.5mm audio and HDMI adapters function? Interested if they communicate over the USB bus or one of the other channels

This is excellent!

Great video. I purchased a dongle DAC to play Apple Music on my stereo from my iphone but discovered that only 4 lightning to usb-c cables in the world can pass digital music stream. Most such cables pass power and some pass digital files but very very few pass digital audio stream. To be clear the cable is lightning male on the iphone end and usb-c male to the input of the DAC. Otherwise you need the apple camera adapter and use a usb A to usb-c cable between the iphone -> camera adapter -> the dac. So lightning cables have lots of hidden protocol checks. I’ve also uncovered that my car’s stereo unit usb input isn’t apple friendly. When i plug my iphone to it, iphone says it doesn’t recognize the accessory. Again passing digital audio stream seems something apple is not making easy.

id appreciate lightning more if the port was more durable. pins should be on the cable imo, hence i prefer usb c. regardless, really informative video
