Tablet As Bluetooth Headset
Okay, so now that Android tablets are getting more popular for in-car use, maybe it's time to propose this on here.
Some of us have Parrot kits and whatnot for bluetooth in the car, but for people using Android tablets, the easiest solution, if it were to exist, would be having the tablet itself serve as a bluetooth headset. This would effectively give you phone conversations over your car speakers, and you could either use the existing mic on your tablet, or you would wire an external one in.
Unfortunately, nothing like this exists so far. There's solutions for seeing your SMS messages on your tablet, but nothing for voice. This appears to be because unlike the bluetooth stack for Windows, the bluetooth stack for Android does not support the Android device itself being used as a bluetooth headset. This concept has been brought up on XDA multiple times, but so far, no developers have picked up this project.
Now, I could be completely talking out of my butt here, since I am not a developer, nor will I ever be, so please bear with me. I've seen some pretty crazy things done with Android, and it doesn't seem like modifying a bluetooth stack would be impossible. After all, somebody wrote that stack, right, and supposedly it's all open source, right? But whatever, let's say it's impossible. How about with the recent merge of the Android kernel with the Linux kernel? I've probably used Linux for about an hour in my entire lifetime, so I'm not sure what all capabilities it has, but I would assume that if the default Windows bluetooth stack has support for headset profiles, Linux probably does, too. Would the kernel merge make it any easier for a developer to get this done now?
Forgive me if I sound really stupid, but I just really want to see this accomplished. It seems like it would be useful to a good portion of the CarPC community, so surely I can't be the only one.
