Maxbotic EZ-4 Sonar

I have connect the MB1240 sonar sensor onto my apm 2.6 running for a quadcopter.

Currently I’m using the version 3.1.5 quad, but under sonar setting, I’m able to enable sonar, but under the drop down box, It does not list down any sonar models, and under my mission planner status, the sonar voltage is always at 0?
are there any methods to resolve this issue?

Just answering this incase someone else runs into this, it’s a limitation in MP for the latest APM 2.6 release, you need to set the parameters manually via Full Parmeter List.

Hi Visser,

I’ve solved this issue right after the developers updated the website on ardupilot.
