Data such as the BER and RSSI is much easier to see in the Pi-star dashboard, but it’s great to see the raw internet traffic with our own eyes in the packet capture. Today we are only scratching the surface of analyzing internet protocol data such as the MMDVM traffic used by the DMR hotspot in Wireshark, but with a little practice, this tool can be used to troubleshoot all kinds of network issues. ![]() While it sure takes a while to get familiar with Wireshark, this information can be incredibly helpful when troubleshooting, just like that trusty SWR meter we know and love. We can see some very interesting information such as my Bit Error Rate (BER), Relative Signal Strength Indicator (RSSI), DMR timeslot in use, and much more. With your packet capture open in Wireshark, type “ip.addr=x.x.x.x” in the “Apply a display filter” box without the quotes, substituting x.x.x.x with the IP address of your Brandmeister master server. To do this, visit and write down the IP address of the Brandmeister master server you’re connected to. Since I only want to see traffic between myself and Brandmeister Network, I can look up the IP address of the Brandmeister server configured in my Pi-Star configuration, and only display that traffic. Now that we have our data available in the Wireshark interface, we need to filter out all of the computer network noise that isn’t related to the DMR hotspot. I’d recommend searching for tcpdump
