Rangefinder not detected

I have hooked up the tf mini plus rangefinder to the pix hawks Serial 4/5. The wiring is all correct and I have done all the correct full parameter tree changes. When I hook it up to ArduPilot im getting PreArm:rangefinder 1 was not detected ardupilot. Cant seem to find what’s wrong. Thank you

You might want to download the latest firmware and test with the GUI from the Benewake website:

I once had an older version that didn’t work until I updated the fm. You could also post or send me the parameters to double check.

Check this for upgrade info. You might need to contact them.

Last time I checked the file was called “TFminiPlus Upgrade Tool.exe”
