hello all

today i use the demo of gnuradio

benchmark_tx.py and benchmark_rx.py

and the demo is work with my two device(e310)

just like 

dev A:/benchmark_tx.py --freq=433e6

dev B:/benchmark_rx.py --freq=433e6

and

dev A:/benchmark_rx.py --freq=433e6

dev B:/benchmark_tx.py --freq=433e6

 this all worked well

then i use tunnel.py to ping two device

just like

dev A:./tunnel.py --freq=433e6

          ifconfig gr0 192.168.200.1

dev B:./tunnel.py --freq=433e6

ifconfig gr0 192.168.200.2

then 

dev B:ping 192.168.200.1  failed

dev A:ping 192.168.200.2 failed

i want to know why the benchmark.py work well but the tunnel.py does not work?

thank you

The tunnel.py program has long given us trouble. One thing to do here is see what happens when you set the transmit and receiver frequencies to different values so you're doing an FDD mode.

Otherwise, there's very little help we can give you since all of the settings make a difference here.
