Working mode switching pin, when the pull-down time is greater than
500ms, the working mode is switched.
The
UART
BAUD
RESET
pin is used to reset the baud rate of the
18
PBI
enter
device. It defaults to a high level when powered on. In any mode, if the
pin is pulled down for more than 1000ms, the serial port parameters of
the module will be restored to the default 115200.
The ACK
pin is used to indicate the last user data transmission status.
