I have been trying to get my digital airspeed sensor to work and while doing some research I came across this post that claims that the "I2C2" port on the PX2.1 does not work:
http://discuss.ardupilot.org/t/pixhawk-2-1-with-maxbotic-i2cxl-maxsonar-ez-issues/15613/12
The proposed solution is to connect the device on I2C1 (on the GPS1 port). Has anyone else encountered this issue ?

The same article I linked suggest that using the I2C from GPS port2 will not work either...

Thank for this, i have this issue on my pixhawk2 and i can't use lidar on the second I2C port.
Is the I2C port of the second GPS is the same as the first GPS ?
So perhaps we can use it without cut the first GPS cable ?
i need to test...
(...) tested, that doesn't work..."
Yes, I was just trying to setup one of the new MS5525 Airspeed sensors on I2C - 2 and it won't work. I'll have to make up a special cable to try it on I2C -1. Someone suggested making a cable to use the I2C bus from GPS-2 connector
