New blog post: Tooling for CSP. CSP is the cubesat space protocol. It is a network protocol used in cubesat buses, RF communications, and groundstations. Here I showcase some tooling to perform CSP network performance analysis and debugging that I have open sourced. There is a tool called csp-iperf that does throughput testing by using CSP ping packets, and a csp-ping-server that can be used in combination with that tool to reply to these packets.

A screenshot of a terminal where we can see csp-iperf running and showing TX and RX rates and packet counts, round trip time measurements, and number of lost packets.
