... Clear-to-Send signals. RTS and CTS are used for hardware handshaking between the host and the LMX9830. Since the LMX9830 acts as gateway between the bluetooth and the UART interface, National recommends to use the handshak- ing signals especially for transparent operation. In case two signals are used CTS needs to be pulled to GND. Please refer also to “ ...
