I am using Ardusub 4.2dev firmware on Pixhawk 1. However, the depth pressure sensor (bar30) doesn’t seem to be registering. I have changed the BARO_PROBE_EXT to 768 but the SCALED_PRESSURE2 doesn’t show up in the qGC Mavlink Inspector. How can I make 4.2dev register the bar30 sensor with the Pixhawk 1?
If I try to change BARO_PRIMARY from 0 to 1, save and reboot in QGC, it shows BARO_PRIMARY=0 again. If I manually change the param file value of BARO_PRIMARY to 1, upload it and reboot, it shows BARO_PRIMARY=0 again.
Any thoughts on how to permanently change BARO_PRIMARY to a value of 1? I suspect that may be why my Pixkhawk 1 is not registering the Bar30.
My suspicion here is that it’s not allowing you to change the value because the sensor is not being detected, rather than the other way around. That said, I’m not sure why the sensor wouldn’t be being detected, so I’ve brought this up internally in case someone else has some idea.
Does it work properly when using the stable or beta firmwares instead of the development one?
