Scanning about 100 beacons at same time

[f.salvatore]

Hi, we have a project in which we have to scan a lot of beacons (up to 100) with Active Scan (scan request and response). We tried to implement this system with actually 6 beacons and we had some problems because with medium large advertising interval (250 ms) and very fast scan windows (25 ms) some advertising were lost. Is it possible to create this system with only one radio that scan with frequency-hopping on 3 advertising channels or we have to use 3 different radios that scan on specific advertising channel?

You will always miss some advertisement packets. Even if you do continuous scanning and there are only one broadcaster you will probably lose 1/1000 packets due to other interference. If you don't want to loose any packets you need to connect to the peer device or implement some system for re-transmitting packets. There is a resent case here about the probability of a packet collision.
