If the server has synchronized to the PA and detected that the BIS is
encrypted, the server writes a value of 0x01 (Broadcast_Code
required) to the BIG_Encryption field of the Broadcast Receive State
characteristic to request a client to provide a Broadcast_Code.
In PTS BASS/SR/CP/BV-14-C test case the PTS (client) expects that the
new value of the Broadcast Receive State characteristicstate will be
notified, so the PTS could sent Set Broadcast_Code operation to the
server.
