PD14
Input
WAKE pin is mainly used to wake up the sleep terminal. It is high level
when powered on. When the pin is pulled low externally, the sleep
terminal device will be woken

PB11
Input
Operating mode switching pin. When the pull-low time is longer than
500ms, the operating mode is switched.
10
PB12
Input
UART_BAUD_RESET pin is used to reset the device baud rate. The
power-on default is high level. In any mode, if this pin is pulled lower
for more than 1000ms, the serial port parameters of the module will be
restored to the default 115200.
11
PB13
Output
ACK pin is used to indicate the last user data transmission status. This
pin is pulled low before the transmission is started, and the pin is pulled
high after the transmission.
