 UCD
 Permits service data to be sent without establishing an explicit L2CAP
channel. It is intended for use by applications that require low latency between
user action and reconnection/transmission of data. This is only appropriate for
small amounts of data
 EPC
 Updates the power control feature to remove the open loop power control,
and also to clarify ambiguities in power control introduced by the new
modulation schemes added for EDR. Enhanced power control removes the
ambiguities by specifying the behavior that is expected. Additionally, a “go
straight to maximum power” request has been introduced. This is expected to
deal with the headset link loss issue typically observed when a user puts their
phone into a pocket on the opposite side to the headset
