Car gateway

[Michel Lopez]

Hello,

I am trying to replace the Audi MMI connect App (available for IOS https://itunes.apple.com/us/app/mmi-connect/id570608111 or Android https://play.google.com/store/apps/detai...udi.mmiapp ) with a generic Upnp/DLNA server running in a Raspberry Pi to stream some internet radios (and eventually some music, but this is not the problem) to the car. By the way this app do not need any account details or even the car to stream, as it can be used as is, with any other end point.

I do know that there are many apps able to do that for most of the phones, but using this type of integration does allow the list of radios to be available in the car menus and enable controlling them using the steering-wheels & dial commands and/or even the touch screen for some newer models. This type of Wi-Fi input seems to be available on many VAG models (Audi, Seat, Skoda, Volkswagen and some others). I do have looked to a lot of software like this one, but so far MinimServer, when installed with MinimStreamer, seems to be the closer (best?) option.

So far I have been able to almost test successfully (almost because I never found a way to get any artwork to show up with any radio streams, but that is a lower level problem) the radio stream with, for example, Windows media player on Windows, or some generic player on phones.

Creating a simple internet radio playlist seems to generate a stream URL that looks very close to what the Audi App is sending. For example, here is a stream Url generated by the Audi app “http://192.168.1.100:50415/webradio/favorite/2865?WMContentFeatures=DLNA.ORG_PN=MP3;DLNA.ORG_OP=01;DLNA.ORG_FLAGS=01500000000​000000000000000000000&WMHME=1&HMEExt=.mp3&WMDuration=625000000000&WMHMETitle=RQB1AHIAbwBwAGUAIAAxACAAWwA2ADQAIABrAGIAcABzAF0A”

Using the car Wi-Fi hotspot, MinimServer is properly found and enabled. I have been able to validate this by adding some music files to the internal SD card, and it does play on the car (with artwork ). The problem is that for the radio playlists, the car player never finds a ‘valid’ entry and always complains that there is no content available. In fact if there is some music content, then all the content is found as expected and the music streams ok. But if I try to play any internet radio playlist entry, it will be tried once, then after failing (and going back to the music) the entry will be grayed out and will not be available anymore.

I have been trying all the options and tricks I could find on the manual, the Faq and even the forum but for now it looks like I don’t see any other options to move forward.

Would you have any idea where to look and what to do next?

Thanks a lot
