I am trying to send a UDP packet from Omnett ++ TSN Device to a standard Host through a TSN switch that is connected to a Router. However, I get the following check_and_cast error:-
check_and_cast(): Cannot cast(inet::physicallayer::signal*)app[0]-0 to type 'inet::physicallayer::EthernetSignalBase *' in module (inet::EthernetMac) of router.eth[0].mac
My omnetpp.ini udp app setup is as follows.
extends = omnetpptsnnetworksample
#Source application
*.tsnDevice1.numApps = 1
*.tsnDevice1.app[0].typename = "UdpSourceApp"
*.tsnDevice1.app[0].source.packetLength = 10B
*.tsnDevice1.app[0].source.productionInterval = 1ms
*.tsnDevice1.app[0].io.destAddress = "ue[0]"
*.tsnDevice1.app[0].io.destPort = 1000
*.tsnDevice1.app[0].source.clockModule = "^.^.clock"
#Sink application
*.standardHost[*].numApps = 1
*.standardHost[*].app[*].typename = "UdpSinkApp"
*.standardHost[*].app[*].io.localPort = 1000
Where did I go wrong?
TsnDevice and TsnSwitch have LayeredEthernetInterface by default, but StandardHost has EthernetInterface. The two interfaces are not compatible (not sure if they should be or not). So by setting standardHost's ethernet interface type to LayeredEthernetInterface, it should work:
*.standardHost[*].eth[*].typename = "LayeredEthernetInterface"
