Hello Bill, I have the ALT-V4's 3-party mode working with my uC. The decimeter data is stable, perhaps only 1 bit of short term wandering. I can see smooth elevation changes as I move the ALT-V4 up and down and the data closely mimics my movements. So that part seems to be Ok.

However, there is something odd going on. My data is not zero referenced. Instead, it is offset by about 4080 decimeters at my location (I'm about 200 feet ASL). I tried another ALT-V4 with the same results.

Is this normal? The 3rd-party data sheet says that the ALT-V4's data should be zero referenced. But that's not what I am seeing, so the reason for my tap on your shoulder.
