Hi Jakub,

> When using LE_SCAN_FILTER_DUP_ENABLE, some controllers would send
> advertising report from each LE device only once. That means that we
> don't get any updates on RSSI value, and makes Service Discovery very
> slow. This patch adds restarting scan when in Service Discovery, and
> device with filtered uuid is found, but it's not in RSSI range to send
> event yet. This way if device moves into range, we will quickly get RSSI
> update.
