RPM reading between MP and QGC

Hi , friend
I can read and rpm from MissionPlanner but I can’t on QgroundControl , anyone can setting and share please.
Best Regards.,

You posted it under the wrong topic, if it works in MP and does not under QGC then it is a QGC bug.

@amilcarlucas , Sorry for my mistake , after reading in MP rpm changed from -1 to 4,800 then never back to -1 while I make disconnected/reconnected by jumper with Yaw port 50Hz , so both are still can’t read and use rpm in backing up throttle curve please.
Can I use only “throttle curve” if I can’t make rpm input to FC please this have any effect or not please?
Appreciate, thanks you in your kind answers
