GPS and Bs2px not working

Hi all, I have recently upgraded my Bs2 autopilot to a Bs2px because I was sorely lacking
in program space. So the first step was to get the GPS working with the Bs2px.
It isn't working and I don't know why. I get a no response error from the GPS.
The GPS is a Parallax unit.
Using the GPS demo code, I have only changed the SIO pin and added conditional compile statements.
The GPS works just fine with this code when used with a BS2.
Thanks in advance,
Rich H

Your code is not setup to use the BS2px as it does not have the correct baud constants. It appears you changed the BS2p constants to reflect the BS2px, but they have different timing, so those values are incorrect. You need the correct baud mode of 813 for the T4800 constant. Take care.
