Syntax:
This command manages the data/AT commands in multiplexing mode. See Appendix B for the
Data/Commands multiplexing protocol description.
<mode>
Command syntax: AT+WMUX=<mode>
Command
AT+WMUX=?
AT+WMUX?
AT+WMUX=1
Note: Enable Data/Commands multiplexing
0
1
Note: The Mulitplexing mode is available to only one UART. If this mode is available on UART1
Multiplexing disabled. When the product is online (data communication in progress), no AT
command can be used (default).
Multiplexing enabled. Data flows and AT commands are multiplexed while in online mode (data
communication in progress).
and the AT+WMUX=1 command is sent through UART2, the multiplexing mode will be
available on UART2 and disabled on UART1.
