I am rooted but this is not about hotspots. Please reread my question. I want to use the tablet as a Bluetooth GPS device.
I know this can be done and I have seen some evidence through some reading while searching. However everything is very vague and the one app I did see had no real instructions and seemed to be so messed up it did not meet NMEA specs.
It would seem so easy to redirect GPS data through a Bluetooth port that I cannot believe this is so hard to find out about.
