◆ EndReceive()

void ns3::lorawan::SimpleGatewayLoraPhy::EndReceive ( Ptr< Packet packet,
Ptr< LoraInterferenceHelper::Event event 
)
overridevirtual

Finish reception of a packet.

This method is scheduled by StartReceive, based on the packet duration. By passing a LoraInterferenceHelper Event to this method, the class will be able to identify the packet that is being received among all those that were registered as interference by StartReceive.

Parameters
packetThe received packet.
eventThe event that is tied to this packet in the LoraInterferenceHelper.
