5.2.3 Echo (+[,<text>])

Format: +[,<text>]

Command + without a parameter toggles the local echo ON and OFF. If sending the + command in Command mode without a parameter, all typed characters are echoed to the output. Typing + again turns local echo OFF. If an input parameter is attached to the command +, the input parameter is directly echoed back to UART.

Default:OFF
Example:+ // Turn local echo on
Response:Echo ON // Echo ON success
Echo OFF// Echo OFF success
