Hello, I’m struggling with a problem on my dropix V1, I noticed that I had intermittent problems with my Airspeed module. So I investigated and here are my findings:
I have a I2C splitter for my compass (which works great) and my digital airspeed from drotek.
When I connect my plane via USB, everything works as expected, however when I plug in the Lipo, my airspeed freezes. If I disconnect the compass it will work again.
When I disconnect the compass and plug in the Lipo, the airspeed keeps working but gives me 5more km/h indicated in Mission Planner.
So there is a combination of a I2C splitter/compass and Lipo powering that makes no sesne to me.
Please note that it does work sometimes (rarely).
I do not have any ferrite on the cable (20cm long) as I believe it doesn’t matter much on a digital sensor.
Also to be noted that in Mission Planner, the checkbox for activating airspeed is greyed out, the use airspeed is worlking and enabled however.
Thanks for your help
