Bluetooth GPS Provider APP
Using an external bluetooth GPS gives you better battery life and more accuracy. Ideal for geocaching and similar applications.
Please note: Most but not all applications will work. (e.g. Wikitude)

The UI is simple to keep the memory footprint as low as possible. If you want to see NMEA data long-press the sat view.
When you have problems connecting to your GPS try different connection methods from the settings. Some devices need a power cycle once the Bluetooth stack had problems (it's a good idea to pull the battery for 30 seconds).
