Bluetooth addr, echoed from
the command
The STATUS value is MPSTATUS_OK if the device is trusted; any other value means not trusted.
If S Reg 47 is set to one, then if the peer device is found in the trusted device database, then the event
EVT_LINK_KEY_EX is sent to the host BEFORE the response. That event contains the address and link
key associated with that address.
8.15.11 Trusted Database Add Key (Out-Of-Band Facilitator)
This command manually adds a link key/address pair into the rolling trusted database.
The module does not care how the key was generated and the only validation it performs is to check that
it is 16 bytes long.
