In some other non-hid app, I can set APP_ADV_TIMEOUT_IN_SECONDS to zero and it worked fine. The advertising is continuous.
But in the ble_app_hids_mouse, I set both APP_ADV_FAST_DURATION and APP_ADV_SLOW_DURATION to be equal to zero, and it no longer advertised.
Please advise how can I get a continuous advertisement in ble_app_hids_mouse.
