upgrade gatt connection performence
when autoconnect flag is used in connectGatt(..),
connection speed is better than another flag true
so only first gatt connection will be requested as autoconnect flag false.
and next connect will be requested as auto connect flag true.
so, background connect will be supported by BT platform.
