I have this idea to use my Jolla to listen to music on my car, and i wanted to do this with an "other half" rather than using a simple audio jack.
The problem is that i don't know anything of the things you need to know to "create" a other half :P
Basically i would stuck a Other Half in the car and use NFC and these pins behind the phone to output audio and charge the phone, instead of jack and usb, where can i find some info about how they work? i mean something more of what is told in the TOH development kit, i really know nothing and need to start from the very basics
