+CIPGSMLOC: 0,0.000000,0.000000

Hi,

I have this model of FONA 808
https://www.adafruit.com/product/2542

I have used an example project in arduino, the GPS is working, but for GPRS I got 0.0000 0.0000 position
AT+CIPGSMLOC=1,1
+CIPGSMLOC: 0,0.000000,0.000000,2020/09/04,20:06:46

I googled for +CIPGSMLOC: 0,0.000000,0.000000 and I found that, is not longer supported by google service:
http://www.embeddedadvice.com/t/sim800- ... on/1878/22

The solution for SIM 800 could be Firmware update
module: SIM 800 formware: 1418B05SIM800L24, and using "AT+CLBS=1,1" instead, but this firmware is not even at official producer web:
https://simcom.ee/documents/?dir=SIM800L

Can you please help to identify, what to do?
I am afraid to use SIM800 firmware to SIM808 module as it has additional GPS an I dont want to lose it.

I have flashed the latest firmware from provider 1418B03SIM808M32_BT_EAT.rar

now I am getting

AT+CLBSCFG=0,1
+CLBSCFG: 0,1,"" the customer ID is missing

and
AT+CLBS=1,1
+CLBS: 4 The number 4 means DNS error

Hi,

according to another blogpost (forgot where, sorry), the GSMLOC project is discontinued. Maybe someone else can confirm that?

Anyways, I was having the same problem as you. I ended up using the
Code: Select all | TOGGLE FULL SIZE
AT+CNETSCAN
command.
Before using the command, set the command config to format 1, to get all information:
Code: Select all | TOGGLE FULL SIZE
AT+CNETSCAN=1

You will get all cell towers with MCC,MNC,LAC and CellID. By using the https://www.opencellid.org/ with GSM-Triangulation (Tutorial here: https://www.radiojitter.com/gsm-trangulation-without-gps/) you will be able to achieve the same as GSMLOC does.
