Trouble with Maxbotix i2c

I’m trying to connect a Maxbotix 1242 I2CXL to Rover and I’m not having much luck, the values for rangefinder1 and sonarrange are always 0.

I tested the sensor with an Arduino sketch and it seems to work fine.

My sensor is currently set to the default address of 112 decimal. (i’ve also set RNGFND1_ADDR to 112 as well (but that doesn’t look like it gets used see below). RNGFND1_TYPE is set to 2.

Hardware (Pixracer):

• fmuv4 0030002D 34355106 37363434
• ChibiOS: 0997003f
• ArduRover V4.0.0 (0e52bafa)

My GPS and the Maxbotix sensor are connected to the i2c bus using a splitter(I used the splitter while testing the sensor with an ardunio).

I actually have two of these sensors, but I’m trying to get one working first (walk before running…)
and it looks like I need to wait for https://github.com/ArduPilot/ardupilot/pull/14079 to get merged?

I originally followed the guide on the wiki but it doesn’t have any troubleshooting info.

I’m not sure what other information would be useful, so just let me know
Thanks!
