BTstack GPS: request for raw bt stream output

[GoogleCodeExporter]

I have some apps that use proprietary or special information from the NMEA data 
stream from my GPS, also there is AGPS which I can upload if I can link to the 
device.  Would you consider adding a port where I can create a transparent TCP 
or other network connection to the bluetooth serial port (even registered only, 
maybe with the GPS app up with a switch in the on position)

I also realized that I have a 3d magnetic sensor as one of the options I merge 
into GPS data in one of the BT units.  It also has accel and gyro, but the iPod 
Touch 4g has those but not the magnetic sensor.  Would it be easy to add 
compass/direction/3d magneto to btgps?

CoreLocation has a "Coures" and a "Speed" field which I have to calculate from 
the difference to the last known location. If there is a standard reporting 
format for those, I'd be happy to directly use those instead of calculating 
them myself.

Extending BTstack GPS to act as a gateway to your Bluetooth device is too 
special. It probably would be better to have your app directly communicate with 
the Bluetooth GPS. I might help out with this, if this is for a commercial 
project with a budget. Please contact me by directly by mail

Course and speed should be part of the standard NMEA, though they call it 
"track".  (sorry for the duplicate post - I spent too long yesterday tracking 
down a heisenbug).  I know you have some of the NMEA docs but here is a quick 
reference:

Speed in knots and true course are shown.  GPRMC is nearly universal.  It has 
been on every GPS and I tend to use it for everything except Altitude which is 
in GPGGA.

Less common but this is the track/speed specific sentence.
