how many centrals can get scan response at once?

[roger.k]

Hi. I'm using nRF52832, SDK13.0.0 as peripheral.

My peripheral is advertising every 400msec and it has advdata and rspdata. As I know, right after a central sends scan request, the peripheral will send scan response.

If there are 10 centrals(active scanning), they will try to send scan request. How many centrals can get scan response at once? Could I say it is 3? Because it has 3 channels for advertisement?

If three, When can remaning 7 devices get scan response? After 400msec? If not three, how can centrals get scan response at once?

Only one scanner per channel. If the advertiser receives multiple scan requests on the same channel, they will most likely interfere with each other before the backoff algorithm kicks in.
