10.2.2 Serial Interface
The serial interface of the module is Logic Level logic levels and the module can be connected to an external μController (see section
Logic level Mode ).
An external driver is needed if the module should be on another physical interface like RS232 (see section External RS232 driver -
External RS422 driver ).
CTS (Clear To Send) and RTS (Request To Send) are used for hardware flow control.
DSR (Data Set Ready) can be used to make a connect attempt. See the Serial Port Adapter AT commands specification.
DTR (Data Terminal Ready) can be used to detect if the module is up and running and ready to receive data.
NOTE
The module must be configured to flow control none if hardware flow control is not used, see the Serial Port Adapter AT
Commands specification.
10.2.2.1 Logic level Mode
The serial UART interface can be used in a host controller application with a UART interface. The design of the interface depends on the
power supply voltage of the host system; see the Logic Levels section for voltage translation.
