Parameter

Size

Description

1Packet_ID

Packet ID: packet Identifier

– For HCI Command Packet_ID = 0x01

2-3

OpCode

OpCode is a unique identification of the command. It

includes

– OpCode Group Field (OGF) of 6 bits. Code 0x3F is

reserved for Vendor command

– OpCode Command Field (OCF) of 10 bits

Parameter_Total_Le

ngth

Lengths of all the parameters contained in the given

command packet (N.B.: total length of parameters, not

number of parameters)

Parameter_0

Each command has a specific number of parameters

associated with it. These parameters and the size of each of

the parameters are defined for each command. Each

parameter is an integer number of octets in size

...
