Bluetooth  4.0 Core Spec  (which can be download from Bluetooth SIG)

section "3 Protocol Requirements"：

"Applications shall not convert a 128-bit UUID to a 16-bit UUID for comparison as there is no guarantee that the 128-bit UUID is based on the Bluetooth Base UUID; it could be a vendor defined 128-bit UUID. 16-bit UUIDs are assigned by the Bluetooth SIG and published in the Bluetooth Assigned Numbers page."
