@jcaron Thank you for answering. My question is not about WPS which is also a very interesting topic anyway or smartphones applications. My question is about GPS and L76 chipset as implemented on the PyTrack. Indeed WPS helps GPS to get quicker resolution. I do agree with you the PyTrack library is very crude, thank you for the last link, this one is helpful.

@pyshi were you able to connect the adafruit gps to lopy4 ?

@robert-hh Thanks for your reply, you have true. I searched components during the starting. And I comment this lines codes : #wlan = WLAN() #wlan.deinit() #bt = Bluetooth() #bt.deinit() #serveur_ftp = Server() #serveur_ftp.deinit() I don't test with each line only, but now it's working. I have fix coordinate when the Fipy powered by Lipo.

If you are unfamiliar with GPS (sounds like that) and curious what "almanac" and "epemeris data" means, have a look at the detailed (and quite interesting) GPS book: https://www.u-blox.com/sites/default/files/products/documents/GPS-Compendium_Book_(GPS-X-02007).pdf

@tttadam Hi. Looks like you might have found my L76micropyGPS.py useful. Any feedback welcome! I just updated the doco as the issue has been resolved, and I had not updated the README.

There are indeed enhanced libraries other contributors already shared, though it depends exactly what data you are looking for. A few links to check out: https://github.com/inmcm/micropyGPS https://github.com/andrethemac/L76GLNSV4/blob/master/L76GNSV4.py from @andrethemac

@abhishek2101 you could print the NMEA and change the if statement in the lib based on what it returns?
