Stefan Olofsson replied to Stefan Olofsson's discussion Sonar not working"Thanks for your reply. I contacted 3DR support with my problem and they gave me an RMA number, I sent it back for about two weeks ago. Havn't heard anything yet but they were really helpful."
Romp replied to Stefan Olofsson's discussion Sonar not working"Same Issue here with APM1 and XL-EZ0 though I haven't tried tapping. Sounds like bad soldering in your case at least.
For me it is between 21 and 25. I can move around at that distance between 21 and 25 and get it to change. anything closer…"

Hi,I have a brand new sonar (order 20017)connected to my APM2 via a servo cable.The sonar always gives 22-23 cm regardless of altitude and this sends my quad into orbit if i switch to alt_hold.I can make the sonar give proper reading for a minute or two if i tap it gently or holding/fiddling with it.What to do?/StefanSee More
exaustgas replied to Stefan Olofsson's discussion Compass /Yaw going crazy"I once had a problem where my compass was faulty which also caused my baro altimeter to not work. maybe they are on the same bus? someone here would know that, but if your baro alt is also not working its a good bet your compass is bad.
