I have a twin motor fixed wing drone equipped with Pixhawk 2.4.6 by mRobotics.
I flew this drone until yesterday succesfully with the fw 1.8, today I flashed to fw 1.9.1 and suddendly, without any change on the parameters, the system doesn’t recognize the airspeed sensor anymore.
The airspeed sensor is this one:
It is connected to i2c bus on a splitter, on the same splitter there are:
- Pixhawk 2.4.6 by mrobotics
- compass of this GPS module: mRo GPS u-Blox Neo-M8N BGP + Duo Mag + USB
- Rangefinder: Garmin LidarLite V3 (already setted up on 1.8 and working)
What could be the issue that makes the airspeed not visible?
Thanks for an help
