I have a car with Android Auto and I’ve seen evidence of it using wifi as its communication and pair up mechanism. The thing is, is my device doesn’t show its on wifi, but here’s the thing…
I have config settings for transcoding while on cellular data and streaming at original FLAC quality when on wifi. When I’m in the car, it will still stream at original quality. I also have only show offline cache rules in place and that seems to be acting like its on wifi as well.
I just wanted to see if anyone else has seen this before I submit an issue with logs. I hope there is some Android framework that allows for differentiation between these two types of wifi connections, otherwise, maybe this is a hard problem to solve. Some quick research does show that AA does the initial pairing via Bluetooth but is doing all the high bandwidth stuff via wifi.
