GPS Module #28146

All,

I recently purchased the GPS Module #28146. I have powered up the GPS Module and per the instrucitons, it blinked for a couple of minutes and then the led remained ON once it acquired a minimum of 3 satellites.

I am using a BS2p24. I modified the program extension from .bs2 to .bsp. I also modified the directive to {$STAMP BS2p}.

I connected Sio from the GPS module to Pin 15. I tried both physical pin 15 and i/o pin 15.

I downloaded the example code from the Parallax website. When I run the program, I receive the "Error: No response from GPS Receiver Module". This is in the code in the No_Response subroutine. So obviously, I am not getting a response.

If a minimum of 3 satellites have been acquired, then why am I not getting a response?

Thanks in advance.

--Neal

    Have you set the baud rate correctly for the bs2p? check SERIN/SEROUT for the settings.

    Franklin,

    The notes in the demo code state that the baud rate is 4800 (Baud CON Open | T4800) and that this should work for all BS2 models.

    Franklin,

    I reviewed the baud rates and discovered that I was using the baud rate for the BS2. While it was still for a baud of 4800, the corresponding Baudmode was not correct for the BS2p24. I changed it to 500 and it now works great. Thank you.
