I have noticed that after a fresh start.. with or without reboot of Pi.. I have to switch track power off/on at least once before any throttle data is actually at the rails.. even though power is on at startup configuration.?
Thinking all this might be endemic to some of the other warnings and things we see with SPROG-Pi and SPROG-1. Our SPROG3''s might also be affected.
