Bad Sonar?

Posted by AlexP on March 4, 2012 at 2:29pm

HI All,

 

I have done test flights (hover only) with my jDrones Hexa. It has the Maxbotix XL EZ0 sonar. Doing some ground tests, the sonar was working fine. Did some initial hover indoors. Ran some tests and all was fine. Sonar gave correct values. Then I went outside and dared to try ALT-Hold. It did not work. Went indoors, ran some tests and the sonar will now only give a value of 675. When I disconnect the sonar, the value changes, so it appears the board is correct. Could the sonar have gone bad?

 

Thanks,

Alexander

    Confirmed: bad sonar. When I tap the board, the values jump down. Hopefully Maxbotix warrantee will cover.
