Depth Sensor Not Connected message

Hi, I built an ROV using the Pixhawk, the 30bar depth sensor, a Pi companion computer, etc. I am running QGC v3.2.4-Blue Robotics Rev6, and firmware 3.5.4. The sensor is plugged into the I2C port on the Pixhawk. I get the “depth sensor is not connected” message, both when attempting to calibrate the sensor, and when attempting to use depth hold mode.

At times, there has been depth data displayed on the widget. And there has been temperature data displayed. And I think it has run the calibration routine once without the error message.

I don’t know where to start to figure out what’s going on. Help?

@jimforbes It sounds like a hardware issue if the depth and temperature readings are intermittent and you get that warning message. Please e-mail us at support@bluerobotics.com and we can begin the RMA process.

New depth sensor appears to be working, it calibrates quickly like it should…thanks!
