Default parameter values：C0 00 00 1A 17 44
Address Channel
0x0000
In sleep mode（M0=1，M1=1） ，
User gives the module instruction (HEX format): C1 C1 C1,
Module returns the present configuration parameters.
For example, C0 00 00 1A 17 44.
In sleep mode（M0=1，M1=1）,
User gives the module instruction (HEX format): C3 C3 C3,
Module returns its present version number, for example C3 44 xx yy.
44 here means the module model (E44 series); xx is the version number and yy refers to the other module
features.
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.
