uBlox GPS data checksum error #50

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
Using GPS emulator to output uBlox NAV-POSLLH format data, the header should be 
"0xb5,0x62" ,but the output data is "0x3F,0x62".

also the checksum is almost error, I found that the checksum number is always 
0x3F.

What version of the Emulator are you using? The current version is v2.2.15.

GoogleCodeExporter commented 9 years ago
Version is V2.2.11  

I installed the new version HK' GCS
http://happykillmore-gcs.googlecode.com/files/HK_GCS_Lite_Setup_08292012.exe

the GPS Emulator is v2.2.11 not 2.2.15, so how can I get v2.2.15 ?

Thanks for your feedback !

What are your regional settings? I see it's set to yyyy/mm/dd for date. What 
country/language do you have selected so I can try it on my end.

That 3F 62 does not appear anywhere in my code. The header is hard coded as 
&HB5 & &H62 so I don't have any idea why it would be replacing those values 
with &H3F

This sure looks like it's a Unicode problem.

Yes,it's  Unicode problem. I change my country/language from Chinese into 
English ,then everything is OK.

Thanks for your help indeed.
