Description

RW MAXLEN

[0..255]

Maximum length of packet payload. If the packet payload is

larger than MAXLEN, the radio will truncate the payload to

MAXLEN.

RW STATLEN

[0..255]

Static length in number of bytes

The static length parameter is added to the total length

of the payload when sending and receiving packets, e.g. if

the static length is set to N the radio will receive or send N

bytes more than what is defined in the LENGTH field of the

packet.

RW BALEN

[2..4]

Base address length in number of bytes

The address field is composed of the base address and the

one byte long address prefix, e.g. set BALEN=2 to get a total

address of 3 bytes.

RW ENDIAN

On-air endianness of packet, this applies to the S0, LENGTH,

S1, and the PAYLOAD fields.

Little

Least significant bit on air first

Big

Most significant bit on air first

RW WHITEEN
