Maybe i am so dumb that did not found whatever you are explaining me, in the webpage you said i found a Python example that use gps.next() to obtain some data stored in "session" but i dont found any explained API for what to do after that.
I found examples on internet that say i can found info into gps.fix.latitude ... or longitude or others but i dont found where can i see all the methods and data packets that gps library offer us.
really thanks Gary, i will git clone the sources and see the CLIENTS.txt file.
