[BLE central] Get the list of all nearby peripheral.

[MartKano]

Hello, 

I'm working on a BLE central multilink application, where I want to get the list of all peripherals in range, In order to let the user select the needed periherals.

I can create a list based on "device_found" callback and delete sensors that we didn't detect since "x" seconds, but I was wondering if there is an easier way of doing so.

Best Regards.

Martin.

I personally use the default found callback and manage the list manually - but you can cut down on the number of things you need to manually filter with the various scan filters as documented in Zephyr.

Ok thanks for the info, I think I'll try something similar then ! 

But If by any chance there is another way of doing so I'll be glad to hear.

Hello Nordic team !

Can you give me more insight on that subject please.

A sample explaining how to handle the list of all connectable device would be appreciate. 

Best regards.

Hi

Please check out the Bluetooth LE scanning documentation for more understanding into how scanning is done. I'm afraid we don't have a specific sample showcasing how to manage a list like this, and the suggested way to do so would be to manage it manually as Sawyer suggested. Do you have a specific question on what you're struggling with on your end we will try to help out.

Best regards,

Simon

Hi Simon, thanks for the response.

What I want to do is having an "updated" list of nearby sensor. In that need I want to know if the sensor is still in range or not.

The issue I'm facing is that I don't know when to delete the sensor from the list when I don't receive advertising packet anymore.

Should I put a timeout for each device on advertising packet, should I try to connect periodically to all detected device to know if there are still in range ?

Or maybe just keep all device scanned in the list.

I'm trying to find the easiest way to do so.

Do you know how the scanning it's done on regular phone ? 

Best Regards.

Martin.
