This one is virtual and does not magically transmit radio waves ;) > So I assume testing with pan --connect, etc also won't work. If you start two entities of hciemu which each its own port number, then you can connect between them. Of course if they are running on the same host, then the network interfaces will not see any traffic. Local traffic goes over the loopback interface. > Are there any tests which we can do with a virtual > hci device ? Plenty of them, but you need a full piconet emulation for anything further.
