The minimum length for one packet is 4 bytes long. The Length is 0x20 based. E.g. the total
length of a packet without command data is 4, the Length byte is 0x20 + 4 = 0x24.
z
The SDTE or RDTE always initiate the communication with Radio module (RRCM,
SRCM). Radio module responses to the command it received.
z
The Command Code for packet sent from SDTE or RDTE to Radio module is even, the
response from Radio module to SDTE or RDTE is 1 higher than the command code.
z
Command Data can be empty.
