Bonding and Pairing
To be able to communicate if security has been enabled, bonding has to be per-
formed. The bonding procedure creates a link key, valid between two devices,
which is used during the authentication procedure. Once bonded the two devices
can establish connections with each other using security enabled.
During bonding both devices must be in pairable mode (able to accept bonding).
Use the “Write_Pairing_Mode” command to set the device(s) in pairable mode.
During bonding a pin code is used. Use the “Write_Fixed_PIN” command to set
the PIN code to use.
To perform bonding use one of the following methods:
•
Create a connection. If authentication or encryption is turned on, on ei-
ther device, bonding will be performed automatically.
• On one device use the “Bond” command. Not supported in all versions of
the serial port adapter.
It is possible for the Serial Port Adapter to store link keys for several devices at the
same time. Use the “Read_Bonded_Devices” command to get a list of the cur-
rently bonded devices.
It is also possible to remove a device from the list of bonded devices. To do this,
use the “Un_Bond” command.
