3.1
The UART interface is the main communication interface between the host and PAN1321-SPP.
The interface consists of four UART signals and two wake-up signals as shown in
Figure 4
3.1.1
The UART (Universal Asynchronous Receiver and Transmitter) interface is compatible with standard UART H4
(4-wire). The lines UARTTXD and UARTRXD are used for commands, events and data. The lines UARTRTS and
UARTCTS are used for hardware flow control. A separate supply voltage, VDDUART, makes it easy to connect
the UART interface to any system.
3.1.1.1
The supported baud rates are listed in
clock generation. The default baud rate is 115200 Baud.
