I got a drone kit with apm 2.8 controller, and am trying to use internal compass. However no dots show up while calibrating the compass in mandatory hardware. Picture attached
How can I debug this issue?
Does apm 2.8 board have inbuilt compass?
Use the latest available firmware → ArcuCopter 3.2.1
Yes, it has an internal compass.
Read this forum section (Hardware, UnSupported hardware) for more help on the old APM 2.8 board
