5.2.4 Enter Command Mode

Format: $$$

This command makes the RNBD350 module enter Command mode and display the command prompt. The device passes the characters as data, and enters the Command mode if it sees the $$$ sequence. If the Command mode guard bit is set using the SR command, the device checks if there are any bytes before or after the $$$ characters in a one-second window, the device does not enter Command mode and these bytes are passed through. For more details on the SR command, refer to Set Application Options.

The user can change the character string used to enter the Command mode using the S$ command. For more details on the S$ command, refer to Set Enter Command Character.

The UART receives a CMD> prompt indicating the start of a command session.
