Today I update our test drone to check improvement on EKF.
HW us cube black with AC 3.6.7 and an arduino that works as converted between serial and Sbus ( serial input converted to Sbus output).
It works perfectly until I update to 3.6.10. Since now Sbus is not read correctly anymore. Pixhawk in failsafe condition. If I press reset button on arduino, random value are read on pixhawk and than stop again.
