There is no API for doing this, because it's not a LoRaWAN concept. LoRaWAN supports class A devices (listen a fixed time after uplink), class B devices (listen periodically, synchronized with the network), and class C devices (listen always). Unfortunately, the LMIC library only supports class A. So the only choice to receive periodically is to send uplinks periodically. You can use the LMIC_poll() api to do this -- this might also be available through the Arduino LoRaWAN APIs.
