Hi, 
 The Bluetooth Specification specifies that the advertising interval should be between 20 ms to 10.24 sec. If you want to be compliant with the BLE Specification, I recommend that you don't try to exceed these limits. 
 That said, you can stop the advertising with the function sd_ble_gap_adv_stop() , and using the advertising module you can start with the function ble_advertising_start() , or directly with sd_ble_gap_adv_start() . You can then set-up a app_timer to control when you want to advertise.
