I seem to be having an issue with getting telemetry from a single KDE ESC. I do have a 120 Ohm termination plug in the second 4-pin JST-GH port on the ESC. I can reproduce on 4.0 stable and master.
If the ESC is set to ID 02, I can receive telemetry just fine (albeit it in the esc1_xxxx, but that’s probably from the best). If the ESC ID is set to “Initial” then I don’t receive any telemetry from the ESC. I can deal with the prearm check about “Too many KDE ESCs”, but it seems odd that ID=02 works and the other doesn’t.
