Why UDP Video Streaming (Server-Client) in OMNET++ and INET is not working properly?

Question

I am trying to simulate a simple UDP video stream in OMNET++ but I don't think it is working properly.

here is a snippet of my .ini file

**.uav[*].numUdpApps = 1
**.uav[*].udpApp[*].typename = "UDPVideoStreamSvr"
**.uav[*].udpApp[*].videoSize = 10MiB
**.uav[*].udpApp[*].localPort = 3088
**.uav[*].udpApp[*].sendInterval = 0.01s
**.uav[*].udpApp[*].packetLen = 1000B


**.gcs*.numUdpApps = 1
**.gcs*.udpApp[*].typename = "UDPVideoStreamCli"
**.gcs*.udpApp[*].serverAddress = "uav[0]"
**.gcs*.udpApp[*].localPort = 3089
**.gcs*.udpApp[*].serverPort = 3088
**.gcs*.udpApp[*].startTime = 0

In this scenario, I want gcs to send request for UDP video stream to server, and UAV should respond with a UDP video stream. But that never happens in UAV (Server) case (see image attached). GCS does send a "VideoStrmReq" but gets no response from UAV. Instead UAV starts sending AODV RREQ.

Could some one please help me figure it out? Am I reading it all wrong? What am I missing? Please help. Thank you.

After thorough analysis and modification, I resolved it by editing the code of my Aircraft.NED file rather than looking for solution in .ini and FANET.NED files.
