Only GT7. Didn't bother for the other two yet. Could add support though, wouldn't take too long.
That's amazing. Any chance of a bianry .. exe plox

Awesome! I'll try it later today. Does it logs the data and save the telemetry file? Do you have any doc about the schema you used? I'll try to figure out what are the unknown channels once I get it running... I'll work on a telemetry analysis tool soon!
it adds a new dimension to the game! Hope it won't get locked by pd!
thanks!
Update for this month wont come out. They will priorize fixing that magic data leak.

Awesome work, kudos to the decryption reverse engineering!
From what i've learned from glossing over the code is that you send your PS an udp 'request' packet and it will send back a encrypted 'telemetry' packet. Decrypt it via Salsa20 and using your magic key and voila, you have your telemetry app.
Will it work only in 'live' mode, i.e. only when you are driving on track or also for replays?
That said, i'm not sure about PD's willingness to go public with that, anytime they want they can plug the decryption hole.

Long time ago we learned that PS4 can have secondary screen on a phone/tablet. From that point, I was wondering why PD and other developers are not using this? I was dreaming about a configurable dashboard or additional telemetry data (like tyre temps).
Is this opportunity mean that someone may develop something like this? If the in-house developers are missing the given chance, I wouldn't mind to run an independent app - if it can have the data... It would be very nice to have just the scenery on TV and dashboard (and game data) on a phone/tablet much closer.

In which case they'd have to bother letting all the vendors know so they can update. I can't see the harm with the sort of information, personally. I couldn't find anything other than pure telemetry. It's barely been changed since GT6 too.Awesome work, kudos to the decryption reverse engineering!

It works in pre-race and in-race. Haven't tested in any other places.

So true, data is harmless, they just have to worry about (and hopefully already have) throttling requests to avoid denial of service.
But the use of encrypted packets leaves me worried. Let's hope for the best.
The tire data looks interesting and there are still some unknowns, hope i can dive into that some more. From what i saw in your packet info there might be temperature/pressure or something along the lines hidden in there.

Very nice. Hope I'll have some time in the near future to see if I can get an Arduino to read the data and control my bass shakers.

Do you think the position/location values (which look reversed... Z, Y, X?) are normalised to real-world units, like metres? I've been looking for ways to determine track elevation for the fantasy tracks to make 3D elevation track guides* (like is shown in the build-up for many real-world race broadcasts) but there was never a way to get heights beyond guesstimation.
* like this, but for fantasy tracks too (and a better resolution lol):
Yeah they do. I could do that as a seperate debug option.
I think it is all in meters yes.Do you think the position/location values (which look reversed... Z, Y, X?) are normalised to real-world units, like metres?

Awesome stuff. Thanks so much for putting in the work and sharing this..
I'm putting together a Python implementation.. I have the message sending/receiving part complete - i.e. I'm getting the data packets (of 0x128 byte size) - but I haven't started on the decryption part yet.
I'm not familiar with C#, so will need to do a bit of research before I can reference your code and reimplement the Salsa decryption functionality in Python... (planning to use: salsa20 - PyPI)
I see you have shared via an MIT license, so if/when I get the Python version working are you OK with me sharing via Github with MIT license (and attribution to you, of course)...?

I added an option --debug to display unknowns.
Yes that'll do. thank you.

This is the discussion thread for an article on GTPlanet:
Gran Turismo 7 Telemetry Data Now Available via Open-Source Software
Over the weekend, we told you about the discovery of a “secret” API in Gran Turismo 7 which enables motion simulators to respond to what is happening inside the game’s environment. Through additional research, this same interface was found to contain a wide range of real-time data, including everything from tire “temperatures”, to engine RPMs, and positional information...

Kaz, use this data to improve FFB in GT7. GT Sport had better FFB vs GT7 and ACC is still better.

Note: while the interface provides some data, and some of that data isn't really visible in-game (tyre temps, etc):
there's an awful lot of basic data that isn't included.
There's absolutely nothing in relation to tyre wear, fuel, hybrid systems, steering input.
You know, all simple important things you would absolutely want from a dashboard or telemetry viewer. 😢

Commendable effort to bring this to the public eye
Hoping to see more developments from this sooner than later
