GSM location

Hi All,

im working on getting the GSM coordinates. This worked till last week with the following commands. But now im getting 0,0.000000,0.000000 as location. even though i didt change the hardware or software. Do you have an idea whats wrong here?

Thanks!

AT+CGATT=1

AT+SAPBR=3,1,"CONTYPE","GPRS"

AT+SAPBR=3,1,"APN","RCMNET"

AT+SAPBR=2,1

+SAPBR: 1,1,"10.151.181.122"

-I have the same problem

MY SOLUTION
I use - sim800l - version with MT6261

-upgrade firmware to version 1418B05SIM800L24

-use SIM800_Series_download_Tools_Customer_v1.19

-not to use the command AT+CIPGSMLOC=1,1

-use command AT+CLBS=1,1

This version "1418B05SIM800L24" didn't work for me.

1418B07SIM800C24_BT actualy this one works - with this tool -> SIM800_Series_download_Tools_Customer_v1.10.

The link above redirects you to a web page that teachs how to update the sim800x firmware with the Tool Customer.

firmware 1418B07SIM800C24_BT is probably for a module supporting bluetooth

I use - sim800L - L version not support BT, L version support FM tunner

BT support in C version sim800C

firmware file name is unambiguous 1418B07""SIM800C""24_BT or 1418B05""SIM800L""24

Klaschni - how is yours SIM800 modul?

thanks for your feedback!
with the old firmware it still doesn’t work. I didn’t try the new one.
I used CENG and took the GPS coordinates from the google data base.
