In the setting mode (M0 indicator light is off, M1 indicator light is on), send a command to the
module serial port (HEX format): C3 C3 C3,
The module will return the current configuration parameters, such as: C3 49 xx yy;
Here 49 represents the module model (E49 series), xx is the version number, and yy refers to
other features of the module (users can ignore it).
Unable to transmit data wirelessly.
Unable to receive data wirelessly.
In an ultra-low power consumption state, all other functions of the module are turned off, and
the sleep mode can only be exited through the state switch of M1M0.

Must be 0xC0 or C2
C0: The set parameters will be saved after
power-off.
C2: The set parameters will not be saved
after power-off.

-----------------------------------
he baud rate of the communication parties
can be different
The serial port baud rate has nothing to do
with wireless transmission parameters and
does not affect the wireless transceiver
characteristics.
-----------------------------------
The lower the air speed, the longer the
distance, the stronger the anti-interference
performance, and the longer the sending
time.
