Dear friends and fans of software defined radio and free/open source radio topics in general, next year's FOSDEM (the free and open source developer's meeting in Brussels, Europe) will, once again, feature a track on Software Defined Radio and other radio-related topics. Therefore, we invite deve

KenI'm using vmware. Not sure if you used the same client but how exactly did you configure your vm to bridged. Also, I used the command to set an alias ip to 192.168.10.1 which is in the same subnet as the N210, not sure if thats different from the manual approach you're suggesting. Tellrell

What are you using as the VM software client (e.g. VMware, virtual box, etc.). I was able to get mine to work but I had to configure my VM eth as "bridged". I also set it with a manually configured ip in the same subnet as the N210. - ken On Oct 6, 2017 10:23 PM, "Tellrell White via USRP-users" <

Hello Guys. I'm currently trying to connect to the N210 using an ubuntu 14.04 virtual machine. I've tried the commands uhd_find_devices and also uhd_usrp_probe and they both indicate "no devices found". Pinging 192.168.2 comes up empty as well. I used the command sudo ip address add 192.168.10.

Piotr, This is especially baffling to me, because I recall that the SKY13335-187LF switches used in B210 must be isolated from DC on all RF ports. But they are! The only components connected to the SMA connectors are a series 470pF capacitor. Perhaps the problem is exacerbated by poor impedance m
