9.3.7
Subgroup “AT BTSEC TRUSTED”
Commands that start with “AT BTSEC TRUSTED” affect the list of trusted
device.
9.3.7.1
AT BTSEC TRUSTED ?
The
AT BTSEC TRUSTED ?
command displays a list of trusted devices that
were able to successfully perform authentication and store authentication data
(pairing). Devices on this list do no normally have to authenticate themselves
when establishing a connection, but can exchange data immediately. For security
reasons, the list is cleared if the setting to force secure authentication is changed.
Informal authentication for commissioning!
During startup, informal authentication can be used to establish connections for
the first time.
Devices to which a connection should be established later can then be easily
applied from the list of trusted devices to the list of allowed devices.
9.3.7.2
AT BTSEC TRUSTED DEL = <Index>
The
AT BTSEC TRUSTED DEL = <Index>
command deletes the device
under the specified index from the list of trusted devices.
Example:
AT BTSEC TRUSTED DEL = 2
9.3.7.3
AT BTSEC TRUSTED CLEAR
The
AT BTSEC TRUSTED CLEAR
command clears all entries from the list of
trusted devices.
