How many broadcasters (Beacons) can be observed by a device which act as a observer only in any nRF devices?

[Ans Hafeez]

I have a scenario in which hundreds of beacons are advertising. I want to know whether an observer can observe all the beacons or not. I have done a lot of search on this forum but found nothing related to my problem.

In other words how many broadcasters can be observed with a single observer.

Thanks..

An infinite number. Since each observation callback is the result of the device in observer mode reading one single advertising packet and there's no relation between them, no storage requirement to remember them or anything else, any number of beacons can be observed.

However the more concurrent broadcasters you have, the more likely their transmissions will overlap and thus you won't see that beacon that time around. If you have enough, your rate of discovery will be fairly slow.

I did a quick calculation in this thread about what the likelihood of you seeing a given beacon is depending on how many you have.

Really thanks for your answer But I am little bit confused. In mobile app it scan and list up all the available devices and if I turn off one of the device then after some time it vanish from list. So can i do that in observer.

remember the devices you see and when you last saw them. At regular intervals remove anything you haven't seen for more than however many seconds you like. That's how the mobile device apps work.
