Hi Cinaed, Sorry to miss the previous email.
I need to clarify that B210 USRP is connected to the PC though USB cable. That's why my Ethernet cards are disabled. Meanwhile I have been trying different things and I noticed the followings: 1- Packet Encoder/Decoder blocks work fine with GMSK modulation scheme. But with other modulation like QAM and PSK, it seems to be less efficient. 2- I can receive any packet delivered to the virtual IP address I create using GNURadio. I also can print them to the console in GNURadio. 3- I can easily send/receive any form of information using GMSK Scheme along with packet encoder/decoder from one USRP to another. 4- but whatever I do I can't put the received packets from virtual IP address though GMSK and packet en/decoder. Sincerely, Mansour. > On 17 Jun 2017, at 02:46, Cinaed Simson <[email protected]> wrote: > > Incidentally, all you need is a $20-$30 Ethernet switch with 5-8 ports, > and 3 CAT-6 Ethernet cables - twice as long as you think might need. > > Then plug 1 one cable into each of the 3 device and plug the other end > the of all the cables into the switch. > > Configure them as below and you should be able to ping all the devices > from either the desktop or the laptop. > > -- Cinaed > > >> On 06/15/2017 02:49 PM, Cinaed Simson wrote: >> >> I'll assume they're connected correctly. >> >> On the both PC1 and PC2, type >> >> ip tuntap del dev tap0 mode tap >> >> On PC1, type >> >> ifconfig enp0s31f6 inet 192.168.200.1 netmask 255.255.255.0 >> ifconfig enp0s31f6 up >> >> On PC2, type >> >> ifconfig enp0s31f6 inet 192.168.200.3 netmask 255.255.255.0 >> ifconfig enp0s31f6 up >> >> Then on either PC, ping the other one.
