Network Over COM.LTE Tutorial

The Network Over COM.LTE mode allows devices to send all network data via LTE when using UIFlow.

Note: When using the CORE2 in Network Over COM.LTE mode, the 5V power supply for M-BUS will switch to input mode. Therefore, please directly input 5V power to M-BUS or use a DC adapter to connect to the LTE module for power supply.
