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
