Hello,
I’m building an autonomous plane for a school project. I wanted to connect a TerabeeRanger Evo 60m to my navio2 with Arduplane 4.0.5. The sensor got a bus address at 0x31 and I can see the device when I run: I2Cdetect. We can’t receive any date from the sensor in mission planner. Maybe the Sensor isn’t capable with arduplane?
Hope someone can help me!

According to the documentation on the manufacturer’s site it is supported from AP 4.0.6 so you have to update your firmware.
Thank you for the Respond!
We have updated the firmware to 4.0.6 (and also the newest) wich didn’t work. We connected the Sensor to a Arduino and the sensor works fine. Any Idea where else the error could be?
I would recommend updating to the current version, the issue might have been already solved if it was in AP.
We have know updated to the latest version of AP (4.5.7). That did not work either.
On the I2C bus is also running an airspeed sensor wich does work alright.
I saw at the documentation that maybe the voltage of the bus is a problem, but the airspeed sensor is also running on a 3.3V I2C bus. We tried also to give the TOF an external source.

Parameter for the Rangefinder
Our Device is not Detected
Reading out the I2C bus and manually measure with terminal
I would try connecting only the rangefinder to the i2c bus, I had an issue where connecting other devices to the bus caused one device to stop working.
We’ve already tried that as well. Are you also working with a Navio2? I’m starting to suspect that the Navio2 might be the issue since everything worked perfectly with the CUAV V5.
