Hi there,
I seem to be unable to get a fix on the ublox m10 gnss. The antenna is connected to J34 on the Hummingboard carrier. I have used cgps to check the fix.
I have the v2x evaluation kit setup.
Here is some output:

The GNSS antenna is indoors but with visible view of the sky. I have used this exact setup with another ublox M9 many times before so really don’t think that’s the issue here.
