Parameters are missing from firmware

Hello everyone,

I am trying to calibrate my BlueROV2 and when I do the calibration of the accelerometer I have this warning that appear :
“Parameters are missing from firmware. You may be running a version of firmware wich is not fully supported or your firmware has a bug in it. Missing params : 1:FLTMODE6, 1:FLTMODE5, 1:FLTMODE4, 1:FLTMODE3, 1:FLTMODE2, 1:FLTMODE1”

I don’t know what am I suppose to do to solve this problem. Someone can help me on this ?

I have also a problem when I calibrate the joysticks of my controller. QGoundcontrol tells me that I am no longer in the manual mode. I continue to do the calibration and it seems to work. I don’t understand this message too if someone has an answer I am also interested.

Thanks in advance.

I had the same “parameters are missing from firmware” message, with the same list of missing parameters, when updating an old BlueROV2 (I think an R2, with a Pixhawk). And accelerometer calibration failed every time. For me, it was solved by updating the Ardusub firmware to the version at:

I can’t connect the BlueROV to my work wifi, so I downloaded the firmware file, went to Firmware at blueos.local, and chose Upload Custom File.

This is actually not the latest version, but I think it’s working for me. After rebooting, accelerometer calibration seemed to be fine.
