3.2.5.1 PairingRequired

When the server receives a PairingRequired message (section 2.2.3.2) in the CONNECTED state, the server MUST send a ReadyToPair message (section 2.2.3.4) to the client, restart the GuardTimer (section 3.2.2), and transition to the WAITING_FOR_PAIRING state.

When the server receives the PairingRequired message in any other state, the server MUST initiate a disconnect of the control channel, stop the GuardTimer, and transition to the FATAL_ERROR state.
