Support for supra connect

[hyonle]

Hi, would like to ask. If the team is considering adding support for supra connect.

Thank you.

Supra Connect does connect to the car over the BMW Apps protocol, so it's possible. However, the only authentication cert that has been found only allows access to the car data. AAIdrive's apps all use certs that are locked to BMW or MINI brands, and so it can not add any apps to the Supra.
AAIdrive does have an 15-month-old branch of code that tries to use this Supra cert to connect to the car and show data, and enable the use of data-only addons. If you'd be willing to test, I would like to stabilize and merge this branch!

[hufman]

I updated the branch, try running this test build and let me know how it looks! It should detect that you have Supra Connect installed, it should connect to the car (untested) with a disclaimer saying most functionality doesn't work, and it should show data in the Car Information tab.

tried it out. it does detects the supra connect . however it crashes when connecting.

here is a screen capture of the process.

Ah thank you very much! As part of merging in the updated code, I missed a Supra-specific cert requirement which had moved to a different file in the intervening months. I sincerely appreciate you enabling crash reporting, that helped me immediately identify the problem!

Please update to the latest APK and try again, thank you very much!

[hyonle]

the latest APK doesn't crash now :)

it looks like its all connecting, all the information shows up on AAidrive

• however i was unable to get the album art to show up on idrive via blue tooth audio
• have tired, deleting and re-pairing the phone, however there is no app options that shows up on idrive

screen capture and screen shots here.

That's great to hear! Thank you so much for testing!

Unfortunately there is no way currently to add new car apps to Supra, without BMW issuing more certs for the J29 brand. The only functionality possible is retrieving the Car Information tab and any car data add-ons. The coverart feature is a part of the Spotify car app, which was only released for BMW and Mini.

I will need to do some minor tweaks (disabling the Navigation tab, for example) before merging it. Thank you again for testing!

[hufman]

Thank you so much for testing! I merged support in 39cd7c4
I'm sorry additional functionality can't be added to your Supra! If you find the car data useful, would you be willing to contribute an app translation in your language?

[hyonle]

english is my primary language. sorry i can't help in this aspect :)

[hufman]

Thank you anyways for testing and confirming that it works, finally letting me merge this branch of code :)

Hi there @hufman
I have a '22 Supra and was wondering if there were any updates or if there's anything that I could do to help further the development for Supra support.

[hufman]

Thank you for reaching out!
The car only allows certs to log in that have a matching brand. All of the car app certs that have been found only include the BMW and MINI brands, except for one special cert that allows car data access from the J29 brand. Without finding any other J29 certs that enable access for adding car apps, AAIdrive can't add any more functionality for the Supra.

[hufman]

@hyonle @Sq00ky Do you still have your Supra vehicles, and are you comfortable with using BimmerCode?
It seems that IDrive will ignore the brand requirement if you code ENTWICKLER_MENUE to aktiv, would you like to try that? I believe AAIdrive may successfully connect with the BMW-brand cert and then connect the car apps like normal.
I'd appreciate any adb logcat -d files of your attempts!

[Sq00ky]

Bingo :)

Updated log set if you want to take a peak - Let me know if there's any issues. All seems to be working. There are a few things here and there, like the "Detailed Vehicle Info" application has no name associated with it in the apps menu and the navigation menu seems to be wonky. will follow up with pictures in a few, but honestly isn't an issue because of the built in navigation functions in the car.

Whoa that's so cool! Excellent taste in music too!
The unlabeled Car Information icon is a known limitation. If you solder some UART and unlock SSH access and edit a .so file, there's a way around it (#801) but I haven't tried it myself.
The map dimensions are defined here heuristically based on the HMI Type, and so it's falling through to a generic guess in your car. We can tune that if desired later, I have an ancient branch that shows custom setters to help tune the dimensions. The same library is used by the Screen Mirroring addon, so it might be worth it.

Thank you for helping, that's so exciting! I'll add some instructions to the app for other Supra owners to enjoy it!

[Sq00ky]

I'll have to look into it one day - it's not the first time I've ripped apart my dash or pulled the head unit, but it'd definitely be the first time soldering headers for UART and CLI access, haha.
Great work as always - I'm sure the rest of the Supra community is going to be thrilled. Having a nice middle ground in between an MMI box is wonderful for everyone.
Super glad you found this and always happy to help :)

I rebased the example-submodule branch, which should build AAIdrive with editable libraries instead of compiled artifacts. Check out the developer docs for more information about building AAIdrive and developing the IDriveConnectKit library.
