C2+ working parameters
C2 + 5 bytes working parameters are sent in hexadecimal format. 6 bytes in total and must be
sent in succession. ( Do not save the parameters when power-down )
4
C3+C3+C3
Three C3 are sent in hexadecimal format. The module returns the version information and they
must be sent in succession.
5
C4+C4+C4
Three C4 are sent in hexadecimal format. The module will reset one time and they must be sent
in succession.

7.2 Reading Operating Parameters
Instruction format
Description
C1+C1+C1
In instruction mode(M0=0,M1=1),
User gives the module instruction (HEX format): C1 C1 C1,
Module returns the present configuration parameters.
For example, C0 00 00 18 00 44.
7.3 Reading Version Number
Instruction format
Description
C3+C3+C3
In instruction mode(M0=0,M1=1),
User gives the module instruction (HEX format): C3 C3 C3,
Module returns its present version number, for example C3 64 xx yy.
64 here means the module model (E64 series); xx is the version number and yy refers to the other module features.
7.4 Reset Instruction
Instruction format
Description
C4+C4+C4
In sleep mode(M0=1,M1=1),
User gives the module instruction (HEX format): C4 C4 C4, the module resets for one time.
During the reset process, the module will conduct self-check, AUX outputs low level. After reset completing,
the AUX outputs high level, then the module starts to work regularly which the working mode can be switched
or be given another instruction.
7.5 Parameter Setting Instruction
The difference between C0 command and C2 command is that C0 command will write parameters into the internal flash memory and can
be saved when power down, while C2 command cannot be saved when power down, because C2 command is temporarily mend
instruction.C2 is recommended for the occasion that need to change the operating parameters frequently, such as C0 00 00 18 03 44.
No.
