Hi Vijith,

[quote user=""]I am working on a project which will connect to device having static mac address . My job is to make sure that the device will connect to device having BLE_GAP_ADDR_TYPE_RANDOM_PRIVATE_RESOLVABLE address.[/quote]

Resolvable addresses can be changed at any time, and thus it doesn't make sense to use that address for directed advertising. Instead undirected advertising with a whitelist should be used. The Identity Resolve Key (IRK) is put in the whitelist, which makes it possible to recognize the Master even though it has changed its address. See this thread.

You can refer to for instance refer to the HID Keyboard Application to see how whitelisting is implemented there. See this post.
