connectBlueA 5V system with open collector outputs is designed in Figure 14.Figure 14: Open collector outputs.10.2.2 Serial InterfaceThe serial interface of the module is Logic Level logic levels and the module can be connected to an external µController (see sectionLogic 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 <strong>data</strong>.NOTEThe module must be configured to flow control none if hardware flow control is not used, see the Serial Port Adapter ATCommands specification.10.2.2.1 Logic level ModeThe serial UART interface can be used in a host controller application with a UART interface. The design of the interface depends on thepower supply voltage of the host system; see the Logic Levels section for voltage translation.Copyright © 2010 connectBlue AB Page 32 of 42
connectBlue10.2.2.2 External RS232 driverAn external RS232 driver is needed if the module should have a RS232 serial interface. See Figure 15 for a complete design examplethat could be connected to the serial port of standard PC. Not used functionality can be left unconnected; see section Serial Interface.Figure 15: A complete RS232 interface.Copyright © 2010 connectBlue AB Page 33 of 42
