Hi,

You just start scanning. If a scannable device is found Android will automatically send Scan Request, get Scan Response and will deliver the merged adv data + scan response to the app. Some phones do this only once per scan for each scannable device found during a single scan, so if you want in addition rssi updates, or the device changes data over time, you have to stop and start scan every ~2 sec. But those were old devices, like Nexus 4 or Nexus 7. Nowadays Android requests scan responses each time it receive the scannable advertising packet.

BR, Aleksander

Not really a Nordic question. I'd suggest finding an android BLE support group to ask the question in as it's entirely .. android.
