[RESOLVED] LightWare SF11/C wrong reading in MP

gnitzan · February 26, 2020, 7:16pm

Hi,
Just finished configuration of a new range finder sf11/c. When connected to usb it reports the exact measurements from the workbench which is 15cm, however, when viewed in MissionPlanner the reported distance is between 24-32 cm.
Using serial5, power is from servo rail (bec) using 4.0.2 fw.
Any idea would be appreciated

Hi Gal,

In MP, do you by any chance have a value at RNGFND_OFFSET?

Hi Mohit,
No, offset is 0.

Here is my params file just in case.

Thanks,
Gal

Well, it turns out that my workbench is black glass, and very reflective.
After placing a white page underneath, measurements are reported correctly.
