Is there a way to reduce the link loss detection time?

[nordicdev]

ble_gap.hHi, At the moment, when a link loss is detected (in a connected mode), it takes around 3 seconds for it to be identified (with DISCONNECTED event). Is there a way to reduce this link loss detection time from 3 seconds to less than a second? Thanks.

This should be parameter set in Connection Request by Master (and possibly changed later on) so it cannot be 3 seconds all the time. What are both sides (HW+SW) of your link? What is in Connection Request during your tests?

Hi Endnode, thanks for the response. Following are my connection interval parameters set at the master: HASH define MIN_CONNECTION_INTERVAL MSEC_TO_UNITS(7.5, UNIT_1_25_MS)
HASH define MAX_CONNECTION_INTERVAL MSEC_TO_UNITS(30, UNIT_1_25_MS)
One side of the link is peripheral (nrf51822: ble_app_hrs example) and the other side is central (nrf51822: ble_app_hrs_c example). I am not sure if this has answered your question.
