Good afternoon: 


 

Recently i purchased a GPS Receiver Module that uses the SX microprocesor. My idea was to use it for a mobile robot that use an existing ATOM 28 from MBASIC.

 

The GPS module blink as expected until light remain fixed, indicating it obtained all the sat data necessary for calculating position.

 

But when i tried to obtain the information, i only receive zeros (no data)

 

Attached i will put a copy of the Basic program.

 

I tried all combination and found equivalence from BS2 to MBasic, but unsucesfully. Could any of you have ideas that will help me?

 

Regards
