unsigned8bit. The data range is 0 ~ 255 (0 ~ 0xFF ). And the format is shown
in the following table. Each data message contains a message ID to distinguish between
different types of messages.

The start Sequence is a constant value 0xAAAA, and the Message ID is defined as follows. The
Data Payload is defined according to the Message ID (see the next section). The End Sequence
is set to 0x5555.

Note
：
The Message ID is represented by 2 bytes, Byte2 is the low byte, and Byte3 is the high byte.
For example, the output of the NRA15 message is 0xAA 0xAA | 0x0A 0x06 | Data Payload |
0x55 0x55, which indicates that the message ID is 0x60A (NRA15 system status) and Data
Payload is the NRA15 system status.
