【NR Cars】Airframe can not be received by vehicle in v2v communication

[sharon1996n]

Hello, dear author.
There occur some problems when i'm using the version 1.2.1 with the simulation-NR-car packet.
I copied the code I rewrote in omnetpp.ini(Figure1). It works well in version 1.1. But the current phenomenon of vehiclesender is that a message can be emitted but it cannot reach the place where it is received(FIgure 2,3).



Something similar happened when I tried to broadcast a message. The frames are almostly the one in the Simulation examples (D2DMulticast). I change the destAddress to 10.255.255.255, and mask the Multicast part in Sender.cc and Receiver.cc.


Hope you can kindly reply to the above two questions and provide some suggestions for implementing broadcast messages. Thank you very much.
