The following values have been defined for use with the Command Status
and Command Complete events:
0x00 Success
0x01 Unknown Command
0x02 Not Connected
0x03 Failed
0x04 Connect Failed
0x05 Authentication Failed
0x06 Not Paired
0x07 No Resources
0x08 Timeout
0x09 Already Connected
0x0A Busy
0x0B Rejected
0x0C Not Supported
0x0D Invalid Parameters
0x0E Disconnected
0x0F Not Powered
0x10 Cancelled
0x11 Invalid Index
Read Management Version Information Command
===========================================
Command Code: 0x0001
Controller Index: <non-controller>
Command Parameters:
Return Parameters: Version (1 Octets)
Revision (2 Octets)
This command generates a Command Complete event on success or
a Command Status event on failure.
Read Management Supported Commands Command
==========================================
Command Code: 0x0002
Controller Index: <non-controller>
Command Parameters:
Return Parameters: Num_Of_Commands (2 Octets)
Num_Of_Events (2 Octets)

a Command Status event on failure.
Read Controller Information Command
===================================
Command Code: 0x0004
Controller Index: <controller id>
Command Parameters:
Return Parameters: Address (6 Octets)
Bluetooth_Version (1 Octet)
Manufacturer (2 Octets)
Supported_Settings (4 Octets)
Current_Settings (4 Octets)
Class_Of_Device (3 Octets)
Name (249 Octets)
Short_Name (11 Octets)
If not short name is set the Short_Name parameter will be empty
(begin with a nul byte).
Current_Settings & Supported_Settings is a bitmask with
currently the following available bits:
1 Powered
2 Connectable
3 Fast Connectable
4 Discoverable
5 Pairable
6 Link Level Security (Sec. mode 3)
7 Secure Simple Pairing
8 Basic Rate/Enhanced Data Rate
9 High Speed
10 Low Energy
11 Peripheral
This command generates a Command Complete event on success or
a Command Status event on failure.
Set Powered Command
===================
Command Code: 0x0005
Controller Index: <controller id>
Command Parameters: Powered (1 Octet)
Return Parameters: Current_Settings (4 Octets)
If discoverable setting is activated with a timeout, then
switching the controller off will expire this timeout and
disable discoverable.
This command generates a Command Complete event on success or
a Command Status event on failure.
Set Discoverable Command
========================
Command Code: 0x0006
Controller Index: <controller id>
Command Parameters: Discoverable (1 Octet)
Timeout (2 Octets)
Return Parameters: Current_Settings (4 Octets)
Timeout is the time in seconds and is only meaningful when
Discoverable is set to 1.
This command can be used when the controller is not powered and
all settings will be programmed once powered.
However using a timeout when the controller is not powered will
return an error.
When switching discoverable on and the connectable setting is
off it will return an error.
This command generates a Command Complete event on success or
a Command Status event on failure.
Set Connectable Command
=======================
Command Code: 0x0007
Controller Index: <controller id>
Command Parameters: Connectable (1 Octet)
Return Parameters: Current_Settings (4 Octets)
This command can be used when the controller is not powered and
all settings will be programmed once powered.
When switching connectable off, it will also switch off the
discoverable setting. Switching connectable back on will not
restore a previous discoverable. It will stay off and needs
to be manually switched back on.
When switching connectable off, it will expire a discoverable
setting with a timeout.
This command generates a Command Complete event on success or
a Command Status event on failure.

into connectable mode. That needs to be done separately.
The setting will be remembered during power down/up toggles.
This command generates a Command Complete event on success or
a Command Status event on failure.
Set Link Security Command
=========================
Command Code: 0x000A

In case the kernel subsystem does not support High Speed, the
command will fail regardless.
This command generates a Command Complete event on success or
a Command Status event on failure.
Set Low Energy Command
======================

This command can be used when the controller is not powered and
all settings will be programmed once powered.
In case the kernel subsystem does not support Low Energy or the
controller does not either, the command will fail regardless.
This command generates a Command Complete event on success or
a Command Status event on failure.
Setting the mode to Central will enable the Low Energy bit in
the supported settings. Setting the mode to Peripheral will enable
both the Low Energy and the Peripheral settings bits.
Set Device Class
================
Command Code: 0x000E
Controller Index: <controller id>
Command Parameters: Major_Class (1 Octet)

Short_Name (11 Octets)
The name parameters need to always end with a null byte (failure
to do so will cause the command to fail).
This command can be used when the controller is not powered and
all settings will be programmed once powered.
The values of name and short name will be remembered when
switching the controller off and back on again. So the name
and short name only have to be set once when a new controller
is found and will stay until removed.
