Document and share GlassInputDevice protocol and functions #316

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
When using the Screencast feature in the MyGlass app on a paired Android 
device, one can swipe on the paired device's display to transmit navigation 
gestures to Glass.

LogCat shows that com.google.glass.bluetooth generates messages tagged 
GlassInputDevice.

Having done some packet capture, I've identified the RFCOMM packets that carry 
the data for GlassInputDevice transmission. Rather than taking on the task of 
reverse engineering this, it would be great to use the existing code 
incorporated in MyGlass.

It would be tremendously useful to have a GlassInputDevice library made 
available for use in 3rd-party Glass companion applications running on a paired 
Android device. In my case, this is to relay input events captured on 3rd party 
HID hardware paired to the phone.

I am interested in debugging and monitoring Bluetooth connections via glass, 
but no tools are available in /bin and we do not have root terminal access to 
the device via adb. 
I would be very interested to look beyond just the HID packets, but be able to 
evaluate BT connections between the paired device and glass (hence the request 
to maybe widen the ability to look into the BT packet stream either on glass ot 
the paired device).
Thanks!

I've also been trying to use android.bluetooth.BluetoothInputDevice but I've 
found that while it is public, I am not able to access it in Android Studio.

I'm trying to get Bluetooth keyboard support working again in XE 17 (Bluetooth 
HID profile) and there is very little (or no) guidance for either Android or 
Glass for how to work with Bluetooth HID devices. The documentation only seems 
to focus on apps that talk to each other via Bluetooth and ignores interfacing 
with actual BT accessories.

Some guidance on how I can use Bluetooth devices to interact with Glass is 
highly desirable.
