BTGPSLib is a shared library for PalmOS to talk to a bluetooth enabled GPS mouse. This library is especially written with NSBasic users in mind, but can be used in other languages that support shared libraries as well.

BTGPSLib makes use of the NMEA protocol and should be compatible with most of the bluetooth GPS mouses available. High level functions for e.g. getting position and time free the user from learning the NMEA protocol. However, lower level functions allows one to use all NMEA sentences provided by the GPS mouse .
