[Discuss-gnuradio] USRP problem

[KC Huang]

 

Hi:

 

I have a problem about USRP daughterboard RFX2400.

 

I use "tunnel.py" to test if some nodes can communicate with each other in 2.4GHz by pinging function. Say there are three nodes: N1, N2 and N3. N1 & N2 can ping with each other and N2 & N3 can receive the ping packets too. However, N1 & N3 cannot receive the ping packet from each other. The distances between these three nodes are same. So, does anyone know what's the reason causes that? Or are there any test scripts can test if USRP works correctly or not? Is it possible that USRP did receive the ping packets but cannot forward them through TUN/TAP driver to User interface?

 

Thanks for any replies in advance!
