CurieBLE: BLE.scan(...) allways scans without duplicate filter

[sandeepmistry]

In https://github.com/01org/corelibs-arduino101/blob/master/libraries/CurieBLE/examples/central/scan/scan.ino:

If I change the BLE.scan(); line to either BLE.scan(true); or BLE.scan(false); all scan without duplicates. I expect it to only receive peripheral per Bluetooth address with the duplicate filter enabled.

This issue is logged as Jira 802.

@sandeepmistry I think touch on this topic before. The latest Nordic stack does not have readily available support for duplicate filtering. Will investigating this issue further.

Ok, if this is not supported by the Nordic soft device stack, the current API's are very confusing and we need to change them.
