Identifying Current Firmware Version

This is perhaps the most difficult step of the process! Click on the Messages window button.

Within the Messages window, you will see a tremendous number of subtrees. Close them all so you only see NMEA, RTCM3, and UBX

Now expand UBX. We need to locate and expand MON, and finally locate VER.

Your device’s firmware will be listed in the right window pane. In this example the Firmware Version is 1.13 and the module is the ZED-F9P.
