: The method is used to re-connect to the remote GATT server LE device after the connection has been dropped. If the remote GATT server device is not in range, the re-connection will be triggered once the server device is back in range. ; Parameter: ''aAutoConnect'':: Whether to directly connect to the remote device (false) or to automatically connect as soon as the remote device becomes available (true).

: A Promise to indicate whether the operation is resolved or rejected. If Once the Promise method is resolvedcalled, it returns property [[B2G/Bluetooth/WebBluetooth-v2/BluetoothGatt#connectionState|connectionState]] becomes <tt>connecting</tt> and a corresponding [[B2G/Bluetooth/WebBluetooth-v2/BluetoothGatt#onconnectionstatechanged|onconnectionstatechanged]] would be triggered. If the connect operation succeeds, another [[B2G/Bluetooth/WebBluetooth-v2/BluetoothGatt#onconnectionstatechanged|onconnectionstatechanged]] would be triggered before the Promise is resolved to indicate property [[B2G/Bluetooth/WebBluetooth-v2/BluetoothGatt#connectionState|connectionState]] object whose connectionState is becomes <tt>connected</tt>. : The promise is Promise would be rejected if 1) the remote LE device is not of type le or dualin range. Once the device is back in range and re-triggered connection succeeds, 2) creation of an [[B2G/Bluetooth/WebBluetooth-v2/BluetoothGatt#onconnectionstatechanged|onconnectionstatechanged]] would be fired to indicate property [[B2G/Bluetooth/WebBluetooth-v2/BluetoothGatt#BluetoothGattconnectionState|BluetoothGattconnectionState]] object fails, or 2) connection to remote LE device failsbecomes <tt>connected</tt>.
