AT BTSEC INQ
This command queries (
AT BTSEC INQ ?
) or determines
(

) if the WSA always (
x =“a”
for “always"), only
when disconnected (
x =“d”
for “disconnected") or never (
x =“n”
for
“never") responds to a device discovery.
Example:
AT BTSEC INQ = n

AT BTSEC PAG
This command queries (
AT BTSEC PAG ?
) or determines
(
AT BTSEC PAG = <x>
) if the WSA always (
x =“a”
for “always"), only
when disconnected (
x =“d”
for “disconnected") or never (
x =“n”
for
“never”) responds to paging (for connection setup, name query, service query).

versions 2.0 or lower if the connection is established by the
other side.
The PIN must consist of a string of max. 15 characters.
Note different PINs!
Note that 2 PINs are distinguished: one PIN for inbound connections and
authentication (AT BTSEC PIN) and one PIN for outbound connections
(AT CON TAR PIN).
Pay attention to matching PINs!
Make sure that the input options on the other side can set the selected PIN. For
example, some external devices only support the characters 0 to 9.
