12.4.4 Paring Method Parameter

The paring method parameter indicates to the IS187x device if the numeric comparison (only for LE secure connections) pairing method available in Bluetooth core specification 4.2 devices must be enabled or not. This parameter is only valid when the link manager version parameter is set to Bluetooth core specification 4.2, making this pairing method available. For more details, refer to Link Manager Version Parameter.

For additional information on pairing with a peer device that does not support LE secure connections, refer to LE Secure Connections Mode Parameter. For an overview of the security properties associated with the different pairing methods to determine the applicability with the application’s security requirements, refer to the Bluetooth Core Specification (4.2), volume 3, part H.
