How to make a peripheral refusing all connection requests?

[kont40]

Hello,

I am using SDK 14 & nRF52832 & peripheral role; I have setup a timeout in the order of several seconds, and during this time my device shall advertise but reject any connections from any central. Where and how to configure rejecting connection requests from central during the timeout and how to enable connection accept after timeout elapses ?

Thanks in advance

P.S. For my application is important to use advertising interval in the order of 20 ms, thus using non-connectable advertising isn't an option.

how about you use non-connectable advertising when you don't want to be connected to then transition to use connectable advertising once you are open for connection.

Thank you for the reply. I have to add that for my application it is important to use advertising intervals in the order of 20 ms, while, according to the BLE specification the minimum non-connectable advertising interval is 100 ms. I have updated the main question with this clarification.

from what I know, Bluetooth SIG had reduced the allowed minimum adv interval from 100ms to 20ms for non-connectable advertising.  But I am not sure though if this is supported by Bluetooth-5 compliant softdevices.

another option i can think of is to try add a dummy whitelist for softdevice to filter the connect reuqest.

Recent SoftDevice versions support non-connectable advertising down to 20 ms.
