+These Telit modems should run fine on the Gateworks SBC (may require GW16140/GW16141 M.2 Adapter)

+Telit LE910C4-WWXD has been tested

+Typical test sequence would be:

+mmcli -m 0
+mmcli -m 0 --enable
+mmcli -m 0 --simple-connect="apn=hologram,ip-type=ipv4"
+}}}

+It may be required to manually set the IP address and other information rather than relying on a DHCP:
