Most likely the issue is one of the following: > [@Depth Sensor Not Connected message](https://discuss.bluerobotics.com/t/depth-sensor-not-connected-message/5351/5): > > Can you confirm > > 1. the following parameters: > > | Parameter | Value | > | --- | --- | > | `BARO_EXT_BUS` | 6 | > | `BARO_PRIMARY` | 2ndBaro (1) | > > 2. that the sensor is plugged in to one of the `I²C 6` ports, rather than one of the ADC ports in the top row but if it’s a parameter issue then there may also be problems with other parameters, which is why I suggested resetting all to defaults 🙂 Bar30 should definitely work with Navigator, and it would be very unusual for two sensors or three boards to be faulty in the same way. --- _[View the full topic](https://discuss.bluerobotics.com/t/pressure-sensor-bar30-depth-sensor-not-connected-navigator-raspiberrypi4/12776)._
