I am using heavy config BROV2 with the new BlueOS and flight Navigator. I am using firmware beta 4.1.0 and QGC ver. 4.2.2. When I connected it all to test in tank, I can’t use depth hold mode because the error message “Depth Sensor not connected” appears. I checked parsmeter BARO\_PROBE\_EXT to be at 768 like recommended to me in previous post ([Water Linked DVL A50 Support - #44 by Jnyberg](https://discuss.bluerobotics.com/t/water-linked-dvl-a50-support/9123/44)). I also have the Bar30 sensor connected in the 12C port like it was on the pixhawk. What else can I check to find out why it is not connected?
