[Nottingham] USB dongles/widgets for GNSS (GPS, GLONASS, others) and 3G/4G SMS & data?

[Martin]

Folks,

Anyone any experience with the various £10/£20 USB dongles on linux for
GPS and internet?

I'm wanting to upgrade one of my RasPi boards to find out for itself
what time it is, where it is, and to be able to communicate to the world.

Are the USB gizmos any good? Anything to watch out for?

There looks to be LOTs of 'em! :-) All with Marketing details only :-(


Cheers,
Martin
