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 18 20 00.
In setting mode（M0=0，M1=1）,
User gives the module instruction (HEX format): C3 C3 C3,
Module returns its present version number, for example C3 43 xx yy.
43 here means the module model (E43 series); xx is the version number and yy refers to the other
module features.

-------------------------------------------------
UART baud rate can be different between

communication parties
The UART baud rate has nothing to do with

wireless transmission parameters & won't
affect the wireless transmit / receive features.
-------------------------------------------------
------------------------------------------------
The lower the air data rate, the farther the

distance, the stronger the anti-interference
performance and the longer the transmission
time.
The wireless transmission rate of both sides

must be same.
----------------------------------------
00H-3FH，

Correspondnig to 425~440.75MHz
