Problem with Fastrack supreme and GPS module


#1

Hi all,

I am using a Fastrack Supreme with a IESM–GPS+USB module.
I want to check if the GPS is working.
Following the post found in “Please help my actived CGPS” topic I done

at+wopen=0
OK
+WIND: 13
+WIND: 12,0
+WIND: 1
at+wopen=3
OK
+WIND: 7
at+wdwl
+WDWL: 0
I downloaded (trough the RS232, using hyper terminal) the ads_queryApp_256.wpb.dwl file. And after:

at+cfun=1
OK
+WIND: 13
+WIND: 12,0
+WIND: 1
+WIND: 7
at+wopen=1
OK
+WIND: 13
+WIND: 12,0
ERROR
+WIND: 1
+WIND: 7
at+whcnf=0,0
OK
at+wiom=8,1,0
OK
at+wiow=8,0
OK
at+nmea=0
ERROR
at+cgps=2
ERROR
at+config=1

The green LED flash only after an at+wopen=0 or 1. After the led is always is off
Please, someone can help me

Hi,
I think you should download the appl again, maybe it have a problem. It must be responsed OK instead of ERROR with these command (AT+NMEA, AT+CGPS, AT+CONFIG)

Version of the application ( compiled by corresponding OpenAt ) must be compliant with firmware downloaded to your modem. However it shouldn’t be successful to download incompatible application to modem, but sometimes I have noticed is possible. In that case application will probably works unpredictable. So please check compliance of your FW and application, and if it is incompatible, compile code on proper OpenAt
