All profiles use same settings currently, probably no need to have 
different configurations for profiles.

So one command which switches fast connectable on/off for both BR and 
LE? And two for configuration?  Maybe something like this?

Set Fast Connectable Command
============================

Command Code:           0x0001F
Controller Index:       <controller id>
Command Parameters:     Enable (1 Octet)
Return Parameters:      Status (1 octet)

Configure BR Fast Connectable Mode Command
==========================================

Command Code:           0x00020
Controller Index:       <controller id>
Command Parameters:     Page_scan_type (1 Octet)
                         Page_scan_interval (1 Octet)
Return Parameters:      Status (1 octet)

Configure LE Fast Connectable Mode Command
==========================================

Command Code:           0x00021
Controller Index:       <controller id>
Command Parameters:     Adv_interval (1 Octet)
                         ...and maybe some other settings if needed
Return Parameters:      Status (1 octet)

I guess the default (fast connectable off) values can be hardcoded since 
they should be always the same. We could also read the original value 
before configuring, but then we can't know if it's really the default value.
