Hi,
I am having trouble with the tunnel.py in the digital foler appear to stop working after a while when using lower bitrates (around 0.5 MB/s) . When I first set up the newtork I am able to ping other nodes with no problem. After some time (sometimes less than half an hour) the pings are no longer sucessful. I checked and the gr interface remains up and correctly configured with the ip address. When I ping out any host I can see the transmission on a spectrum analyzer so I know the transmit path is still functioning. Higher bit rates seem to work for much longer periods of time. Has anyone else had similar issues with these bit rates? If so has anyone figured out the cause of the lost connectivity?
I am using USRP2s with WBX cards and using 400 MHz carrier frequency. No other application traffic is being sent over the network.
Thanks,
Dave
