In sleep mode (M0=1, M1=1), issue a command (HEX format) to the module serial port: C3
C3 C3,
The module returns the current configuration parameters, such as: C3 32 XX YY;
C3 is the command prefix, 32 represents the product model, XX represents the version
number, and YY represents the interface format + the maximum power value of the module
(hexadecimal). The TTL interface is 0x10, RS232 is 0x40, and RS485 is 0x80
In sleep mode (M0=1, M1=1), send a command to the module serial port (HEX format): C4
C4 C4,
The module will generate a reset;
During the reset process, the module conducts self-check, and AUX outputs a low level.
After the reset is completed, AUX outputs a high level and the module starts to work
normally;
At this point, a mode switch can be performed or the next instruction can be initiated.

The serial port modes of both sides of the
communication can be different
The baud rate of both sides of the
communication can be different. The baud rate
of the serial port has nothing to do with the
wireless transmission parameters, and does not
affect the wireless transceiver characteristics.
The lower the air rate, the longer the distance,
the stronger the anti-jamming performance and
the longer the transmission time.
The air wireless transmission rate of both
parties must be the same.
