Scanning without duplicate packets in one scan window

You need to stop scanning or update the filter settings to prevent further advertisement events from the same Beacon in the same scan interval. Alternatively, add your own custom filtering in your scanner callback. The scan module does not provide a setting to filter out "duplicates".

I though I have explained by question very well or I have no understood your answer.

What I am talking about is getting duplicate packets while scanning. What you are talking about is filtering based on UUIDs or white list. I am already filtering out packets based on UUID. What I want is a parameter by which in one scan window I only get one packet not multiple packets of the same device.

Another Example:

Device 1: Beacon, transmitting at 100 ms

Device 2: Scan interval 10,000 ms & Scan Window 500 ms

If I run the devices on there configuration I will get 5 packets on each scan window/interval, these packets are duplicate packets of the same device(Device 1).

So I am looking for a parameter which can be set to remove the duplicates while scanning.

Hello,

I'm assuming you're using the Scanning Module. The module will always notify the application when it gets a filter match, so you either have to stop scanning or dynamically update the filter settings to stop receiving scanner events for this device.
