Hi Matthew,

The SEC_PARAM_KEYPRESS is one of the security parameters used for security procedures, as shown here: https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/lib_pm_usage.html?cp=9_5_13_3_1_11_2_0#lib_pm_usage_init

Thank you Priyanka. I think that Nordic documentation link doesn’t explain exactly what this the keypress notification.

can you elaborate on this please? Is this a Nordic custom thing or a standard thing defined in the Bluetooth Core BT spec?

what’s the use case of this keypress notification?
