Frame

The frame has one or two parts depending on command name header and data.

Nodes discard frames longer then 64 bytes.

There are UART commands and Radio commands. The UART commands do not result in any radio communication and are handled inside the PC node only. The Radio commands cause radio transmission and the answer from PC node depends on the radio communication result.

Example of UART command frame

1	2	3	4	5	6	7	8	9
Length	ID Info	Command	GRP	ID	CRC	Data	Data	CRC
09	00	10	01	01	CRC	GRP	ID	CRC

Example of Radio command frame

1	2	3	4	5	6	7	8	9	10
Length	ID Info	Command	GRP	ID	To ID	CRC	Data	Data	CRC
0A	11	35	01	01	02	CRC	CAL_V	CAL_V	CRC
