In AT command mode, echo on means the module could directly respond any input command line to the
serial interface. Thus, this option may help users more easily through serial terminal software manually.
However, this may increase the difficulty to parse the return output if the serial is connected to an MCU
in an embedded system. Turn echo off in this case.
