Feels like Crossfire development is abandoned?
I do get different RSSI on the antennas in Blackbox using the Uplink data setting so i guess its working on that end but telemetry that is sent to the radio is a duplicate? I also have other issues like logging on the radio puts the values in the wrong column so i had to manually edit the logfile to put them in the right order again. That bug also appeared after updating to newer firmware.
