+# Network Over COM.LTE tutorial
+
+>Network Over COM.LTE mode enables all network data to be sent via LTE when the device uses UIFlow.
+
+>Note: When `CORE2` uses `Network Over COM.LTE mode`, the 5V power supply of the M-BUS will be switched to input mode, please directly input 5V power to M-BUS or use a DC adapter to connect to LTE The module supplies power.
+
+## Pre-requirements
+
+### Driver Installation
+
+>Before we start programming, users of M5Core type host (including BASIC/GRAY/M5GO/FIRE/FACES/CORE2) should download the corresponding CP210X driver compressed package according to the operating system you are using. After decompressing the package, Select the installation package corresponding to the number of operating systems to install.
