No Sonar reading with Maxboticx EZ4 and Pixhawk over I2C

I have a new Maxboticx EZ4 1202 - I intiallly followed the instructions here:

copter.ardupilot.com/wiki/common … ix-analog/

but got no readings and then found the link here:

copter.ardupilot.com/wiki/common … xbotixi2c/

which I followed and rewired for however again I’m getting no sonar readings on my status page. I’m unsure what I’m missing. I’m running 3.3.3 beta

This seems to have been resolved through some mix of configuration resets and tinkering. I wish I could pin it down - it could have been a firmware version thing as I think I somehow reverted my quad to 3.3.2 in the last few weeks.
