With the bluez stack, is it possible to connect multiple audio sources ? How ? If not is it possible by any other means ? If possible, is it possible to mix different bluetooth version like low-energy with old ones ?
If not possible, I think a (costy) solution is to plug multiple (physical) bluetooth receivers behind my (physical) audio mixer ^-^
Background: I'm trying to build a "media server", and I want phones to be able to stream audio to it, but I don't want to hear "please, can you disconnect your [not actually playing music] phone so I can connect mine".
