Pairing
When this register is 1, in MP Mode it enables the
EVT_LINK_KEY_EX event to send to the host when the
module receives the CMD_TRUSTED_DB_IS_TRUSTED
command and in AT mode it enables the AT+KY?
command so that the link key information sends to the
host in the response.
By default this key is 0.
By setting this to 1, the customer acknowledges that
security can be compromised.
