Not Getting "FIXED" with F9P and NEO-D9S

Has anyone had success getting the F9P example script (Example19_LBand_Corrections_with_NEO-D9S) to run and get RTK lock? When I run it, I don’t get FLOAT or FIXED, just “Carrier Solution (None)”.

A little background on my setup: I am using an F9P connected via I2C (and UART2 concurrently) to the NEO-D9S. My antenna is a roof-top mounted Ublox multi band with clear view of sky. I connect to the F9P via a Teensy 3.6 with I2C. So the setup is

MacbookPro - USB - Teency3.6 - I2C - F9P - I2C/UART2 - D9S

When I take the same setup and run it through U-Center, I get FIXED lock within a couple of minutes. That setup is

Win10 - USBC - F9P - I2C/UART2 - D9S

My guess is that there’s some parameter that’s either missing from the Example19 script, or that’s different than the U-Center defaults. It could also be something related to the Example19 script using I2C to talk to the D9S, whereas U-Center uses the UART2. I’ve spent several hours trying different things with the Example19 script, but no luck thus far.

Any suggestions appreciated!!
