[USRP-users] UBX-160 with X310 communication issue

Mark,
“Ping” (ICMP) is implemented using a micro-controller and (different) firmware in both the N210 and X310. It’s very much Control Plane functionality and not indicative of Data Plane performance (i.e radio data and control packets) which are handled very deterministically by different dedicated packet processing hardware.
