Hi I have just purchased another v2.5 ardupilot and a 2 x sonar (MB 1260)

It is connected to A0 as per instructions. It is enabled with correct option selected (2=XXL) this has been done both under config table and also tried via CLI terminal.

When I test the sonar under CLI I get 1068 with no change or fluctuations. It makes no difference what is in view of the sensor at different ranges.

I am using Mission Planner 1.2.14 mav 1.0

AP is set as Arducopter V2.7.3 sonar enabled option 2=XXL 

I have verified 5.01v at the sensor.

So does anyone have a clue what I am doing wrong?? 

I might also mention I have 3 V2.5 ardupilots here and 2 of the MB1260 maxsonar's,   checked multiple sonars on multiple Ardupilots,   same result every time.

I have even tried uploading the firmware from another PC and running it from the other PC.... no change in the result.

I haven't had an issue that I was not able to solve until now....

I am really excited to play with the sonar, just wish I knew what I am doing wrong!!

Cheers

Steve
