Why do you call that an “error” :question:

It says, “GPS Fix not obtained yet” - it takes time to obtain a GPS fix, so you have to wait for it :exclamation:

Are you sure you aren’t just being impatient…? :wink:

You haven’t provided any additional information, and haven’t answered previous questions:

Hi ppl! I have the same problem - “GPS Fix not obtained yet”… I was waiting for 40 minutes, but answer was the same… Where can be the problem? (In addition to my DNA =))) )


#7

Hi all,
I think you must enable some pins before using the first time, following this guide:

Config one time after download firmware or the first time run modem:
AT+WOPEN=0
AT+WOPEN=3
AT+WDWL
… Download Embedded appli
AT+CFUN=1

AT+WOPEN=1

AT+WHCNF=0,0

AT+WIOM=8,1,0

AT+WIOW=8,0

To debug:
AT+NMEA=1 (or = 0)
AT+CGPS = 2
AT+CONFIG=1 (To save and run always run appl)
(Can send SMS for PVT obtaining: INFO:“Password”:“Phonenumber” )
{Exp: INFO:CGPS[:telephone number]}

Hope help you,
ttt

Thanks trthaithong, but it’s still not working… The reply is “GPS FIX NOT ACHIEVED”. What is it means?
