2.6. Hardware Physical Interface
2.6.1. UART Interface
Four signal pins are used to realize UART function. When DX-BT24-T is connected to
another digital device, UART_RX and UART_TX transfer data between the two devices. The
remaining two pins, UART_CTS and UART_RTS, can be used to implement RS232 hardware
flow control, and they are both active at low level, that is, transmission is allowed at low level,
and transmission is stopped at high level.
