At the moment I'm developing a App for the new Live Data Interface and will share it trough Git if anyone is interested. Will include a complete Onboarding Wizard for pairing etc.

Best regards

  Hi there :)
  The app is almost ready.

  I sucessfully installed it on my Karoo and registered all available Datafields from the Bosch LDI. I think some will be useless like a Field for diagnosic port, charger connected, eBike locked ...
  
  

  Interesting Fields are SPEED, CADENCE, RIDER POWER, BATTERY, LIGHT STATUS, ODOMETER.
  
  My last step ist now the configuration menu with onboarding wizard for bike connection. You can connect 4 different bikes to one computer (for those who got more than one bike ;) )
  
  Another problem at the moment ist installation of the app. It's no longer possible to just send the link to the hammerhead companion app. I will try to list the app at hammerheads directory for easy installation.
  
  I will keep you up to date with screenshots as soon as it works :)

  Hi. Status atm:
  - App is working
  - All Fields registered
  - Onboarding wizard working
  - German and English language
  
  Problems:
  - binding a eBike won't work - maybe some BLE problems, needs some more debugging

  Hello Julian!

  Is there anything that can be done to support your work?
  Do you have a repository or a web site for your project?

  Hi there :)

  I had not much time in the last weeks. I already done some fixes for Bluetooth but had no time for testing.
  Yes, i got a repository - Everything is on GitHub but not at public access ATM.
  
  If you give me your GitHub Infos, I will get you access.
  
  Best regards

  I simply switched the repo to public. Think it's easier. https://github.com/julianhaas386-oss/Bosch-LiveDataInterface-for-Karoo

  Best regards. I will get on testing when I have more time.

  Well this will probably not work for the foreseeable future in general.

  BLE Advertising is not allowed on Karoo Devices for 3rd party Extensions. This is the key factor tho for it to work.

  We can only wait and hope that Hammerhead will consider making a first party integration for this since opening BLE Advertising for 3rd party apps is a bit risky from a security standpoint and shouldn't be allowed. 

  The feature will only work on Karoo 3 devices tho since BLE Advertising is only possible in Android 12 and above.

  The Karoo 2 is still based on Android 8.1 so this feature cannot be implemented for it.

  I just tried it, but as soon as I started the installed extension, it freezes with inside the white screen where "Bosch LiveDataInterface" is written.

  Hi. What Karoo are you using? The App is dedicated for Karoo 3.

  Seems like he is using a Karoo 3 in the image shown above. There was a new push to the GitHub repo recently. I can test the start of the app again but it still won't work from the BLE Side. So the app being broken isn't a big problem atm

  Same here 1.638.2460.20 and 1.2.20

  if you need some logs or anything else please let me know 

  yes I read below so this is the prob 

  "Karoo firmware currently blocks the necessary BLE advertising for third-party apps."

  Hi Julian,
  what's the status? On my Karoo 3, it's also showing white with the "Bosch Live Data Interface" lettering.

  @Niclas the status is the same. If the Hammerhead team doesn't unlock a specific feature set the app won't work functionally. We have already pointed that out to support and are waiting for the Hammerhead team to implement it.
