+OBEX Connecting State
+This state is entered during an OBEX connection attempt. The authentication state machine is
+invoked via ParseConnectPacket and PrepareConnect packet.
+A successful CONNECT will move the machine to Ready.
+A CONNECT requiring a user password will move the machine to WaitForUserPassword
+Other CONNECT results may stay in this state or move the machine to TransportConnected
+A DISCONNECT will be processed
+An ABORT will cause a Protocol Error
+Any other OBEX operation will be answered with an OBEX error code
