Setting up the PPP connection for Sixfab Shield/HAT
Sixfab offers shields/HATs for Raspberry Pi which provides cellular PPP internet connection anywhere with the availability of mobile network coverage. Each of these shields/HATs can be connected to the internet via PPP(Point to Point Protocol).
QMI Interface Internet Connection Setup Using Sixfab Shield/HAT
Sixfab HATs provide 3G/4G & LTE wireless connectivity, these modems by default use the newer QMI interface as the primary connection method, as opposed to PPP over serial or direct IP as with earlier modems in the range, and are currently best supported by Raspbian OS has support for the libqmi interface tools.
Setting up a data connection over QMI interface using libqmi
Cellular modules that are based on the Qualcomm chipsets support the QMI interface. libqmi can be used to establish QMI interface for mini PCIe modules such as Quectel EC25, Quectel EC21, Telit LE910C4, Telit LE910C1 with the Raspberry Pi 3G, 4G/LTE Base HAT.
