I've got a Pi model 3 B, and I've purchased the following 4G hat, however I'm unsure how to actually establish an internet connection through it.. so hoping for a little assistance, or peoples suggestions.
2G/3G/4G GSM GPRS GNSS SIM GPS Extension Board for Raspberry Pi 2 3B B+ ZeroW GM
I can query the card using minicom -D /dev/ttyS0 and see that its got signal, query the carrier etc. However I'm unsure how to go about setting it up as either a modem or other network device to access the internet.
I've also tried using the USB port (not the one labelled UART), and I get a wwan0 adapter, however it only get a self-assigned IP. Upon connecting it to my Windows computer through the same USB port, I get several devices install, one of which is a network adapter but it shows that the cable is 'unplugged' - I haven't really tried anything further through Windows as this stage.
What I would like to achieve is have the Pi connected to the internet via the 4G hat, and be able to query the GPS part of the card to get the location - I'm not fussed if thats just by command line. I'd like to have it connected via the GPIO pins, but not fussed if it also needs to be connected via USB as well (the manual didn't seem to show how it should be connected unless I missed something?)
