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 reply. The ble_gap.h in the central side is the same as in the example code provided for ble_app_hrs_c. I am not sure which hash define to look for. I have attached my ble_gap.h (which is the same as provided by the example code) herewith. I thought it would be as simple as changing the value of a hash defined. Sorry, I am not very familiar with BT SIG Core spec. Which chapter do you recommend I should have a read in the BT SIG Core spec?
