Baro30 Pressure sensor and Pixhawk4

[EliotBR (Eliot)]

Hi @islamwael,

@EliotBR

The Pixhawk 4 hasn’t been supported until very recently, so there isn’t a stable release for it. To use it with ArduSub you’ll need to use the Development release (ArduSub 4.2) or the Bar30 won’t work, as covered in this thread:
Leak Detector + Bar30 Firmware Pixhawk4

Assuming you’re already on development (directly using the master branch),

@EliotBR

Are you able to confirm/set the following parameters?

Parameter	Value
BARO_PROBE_EXT	768
BARO_EXT_BUS	1

You may need to reset your parameters to their defaults before setting the other parameters will work correctly.
