5 Device terminal description
5.1 UART Interface
The F2M03 Bluetooth module’s Universal Asynchronous Receiver Transmitter (UART) interface provides a
simple mechanism for communicating with other serial devices using the RS232 standard
(1)
.
Universal Asynchronous Receiver
Four signals are used to implement the UART function, as shown in the figure above. When F2M03 is
connected to another digital device, UART_RX and UART_TX transfer data between the two devices. The
remaining two signals, UART_CTS and UART_RTS, can be used to implement RS232 hardware flow
control where both are active low indicators. All UART connections are implemented using CMOS
technology and have signalling levels of 0V and VDD. UART configuration parameters, such as Baud rate
and packet format, are set by Free2move firmware.
Note:
In order to communicate with the UART at its maximum data rate using a standard PC, an accelerated
serial port adapter card is required for the PC.

Uses RS232 protocol but voltage levels are 0V to VDD, (requires external RS232 transceiver IC)
