INFRARED ASSISTANCE

IR assistance serves two purposes:

‐

Provides a trigger to the STB in the form of an IR command that the STB can use to start listening for

Bluetooth adverts.

‐

Provides a mechanism for the STB to optionally restrict offering a connection request only to the RCU that

sent the IR command.

IR assistance behaviour does not depend on the method of pairing initiation; i.e. both 'auto-pairing' and manual

pairing methods shall use IR assistance.

Action

Table 3: IR assist state table

Note that the host response to use the second frame in the Macro for restrictive pairing is optional.

It offers a mechanism to restrict pairing to the device sending the IR frames but it is the host

decision to make this restriction and hence does not prevent pairing by default.
