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 32 xx yy. the second bytes means
frequency. 32 here means the frequency is 433MHZ, 38 means frequency is 470MHz, 45 means
frequency is; 868MHz, 44 means the frequency is 915 MHz, 46 means the frequency is 170MHz;
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.
