Iris+ will not connect to MP, flasing red light with buzzer and solid red LED light on Stern.

Posted by Logan Spencer Kirk on January 4, 2015 at 11:42am

So i have been attempting to get my Iris+ to connect to Mission Planner on my laptop so that i may attempt to fix some of the issues i believe it may be having thus far regarding the EKF and the Compass.  Here is the link to my previous post describing what has happened up to this point with response from other member here at DIY drones.

I turn on my Controller, Plug in the battery on the Iris, the warning light flashes red repeatedly and the LED light on the Stern is a solid red with a warning buzzer going off repeatedly.  I am unable to connect it to mission planner using an open com port and the 57600.  Has anyone ever experienced this? I cannot find info on this particular issue anywhere online and could use some help

here is a video of what it is doing

    Update: so the Iris is once again operational and all systems are nominal at 100%. I was able to get some help from the guys over at ATI in Portland Oregon and after a couple hours of troubleshooting we where able to get it fixed. After resetting the pixhawk back to the OEM settings for the Iris and a couple of calibration settings for the GPS and RC, and some quick hardware re-arrangements we managed to get her In the air and flying correctly. Apparently their was some manual changes made during set up that greatly affected the Iris on top of the set up having been done for the wrong copter as well as having the GPS installed facing the wrong direction. Hence the incorrect heading direction on the MAVLink. We also could not retrieve the data from the first crash but believe it was the same malfunction caused by the incorrect values and set-up that caused the second crash. Thank you for the help getting my Iris up and running once more! This was one heck of a lesson for me and I learned way more than I thought I would.

    Hi Logan,

    Couple of questions:

    Has it been in the air since the above mentioned crash?

    Have you attempted the start up procedure with success prior to this issue?

    Have you removed the SD card from the PixHawk and looked at the files for any errors?

      Couple of questions:
      Has it been in the air since the above mentioned crash?
      I have not had it back in the air since the last crash

      Have you attempted the start up procedure with success prior to this issue?
      I have not been able to have a successful start up since the last crash. Have onLy had unsuccessful startup attempts.

      Have you removed the SD card from the PixHawk and looked at the files for any errors?
      I removed the sd card from the PH in order to get to the data flash logs. I just realized I have not re-installed it as its sitting in my card reader still. Would the sd card not being in the PH cause this lack of start up? I am going to re-install it and attempt the start up procedure again. Feelin like a dumb ass about this but I appreciate the help.
      Thank you Todd.

        No SD card = Unhappy PixHawk.

          geez, I feel very much amateurish.  It was most definitely that there was no sd card in the PixHawk.  That is a mistake i WILL NOT make again as it only served to provide me with hours of fun not being able to connect to the Iris.  I am very grateful for your list of questions as it is what helped me to be aware of my mistake. The Iris is now connected to mission planner and I can begin the procces of learning how to change the parameters that caused my original crash issue.
