Similarly, any mode switching can use this feature. After the module processes the current mode event, it will
automatically enter the new mode within 1ms; thus eliminating the need for the user to query AUX and achieve the
purpose of fast switching;
For example, switching from the transmit mode to the receive mode; the user MCU can also enter sleep before the mode
switch, and use the external interrupt function to acquire the AUX change, thereby performing mode switching.
This operation mode is very flexible and efficient, and is designed according to the user's MCU's operation convenience,
and can reduce the workload of the entire system as much as possible, improve system efficiency, and reduce power
consumption.
6.2 Normal mode（Mode 0）
Users can input data through the serial port and the module will start wireless transmission.
The module wireless receiving function is turned on, and after receiving the wireless data, it will be output through the serial
port TXD pin.
6.3 WOR mode（Mode 1）
When defined as a transmitting party, a preamble is automatically added before transmitting.
It can receive data normally, the receiving function is the same as mode 0.
6.4 Configuration mode（Mode 2）
Wireless transmitting off
Users can access the registers to configure the module's operation state.
