Hello everyone ...

i have SIM800L module (mini Red PCB), and i have some questions for how can i using
AT+CIPGSMLOC for finding sim location, im establish a GPRS connection and try to
get location but it shows Latitude & Longitude zero in serial mon.

here is my output of serial monitor:

AT+SAPBR=3,1,"Contype","GPRS"
OK

AT+SAPBR=3,1,"APN","mcinet"
OK

AT+SAPBR=1,1
OK

AT+SAPBR=2,1
+SAPBR: 1,1,"102.22.217.68"
OK

AT+CIPGSMLOC=1,1
+CIPGSMLOC: 0,0.000000,0.000000,2020/12/31,17:57:29
OK

AT+CIPGSMLOC=2,1
+CIPGSMLOC: 0,2020/12/31,17:58:14
OK

AT+CIPGSMLOC?
ERROR

AT+CIPGSMLOC=?
+CIPGSMLOC: (1,2),(1-3)
OK

AT+CIPGSMLOC=1,2
+CIPGSMLOC: 601
OK

AT+CIPGSMLOC=1,3
+CIPGSMLOC: 601
OK

AT+CIPGSMLOC=2,3
+CIPGSMLOC: 601
OK

Thanks !

i found AT+CLBS command for location but it returns TIMEOUT and NET ERROR ...

//Activate a bearer, serial port result is[RighTel]:

AT+CLBSCFG=0,1
+CLBSCFG: 0,1,""

OK
AT+CLBSCFG=0,2
+CLBSCFG: 0,2,1

OK
AT+CLBS=1,1
+CLBS: 2

OK
AT+SAPBR=0,1
OK

//Activate a bearer, serial port result is[mcinet]:

AT+CLBSCFG=0,1
+CLBSCFG: 0,1,""

OK
AT+CLBSCFG=0,2
+CLBSCFG: 0,2,0

OK
AT+CLBS=1,1
+CLBS: 3

OK

so whats the problems with this commands ?

Where did you get the information regarding the AT+CLBS command? I cannot find it in the SIM800L command set documentation (V1.09)

i get from Application Note from simcom !
SIM800 Series_GSM Location_Application Note_V1.02.pdf

its for SIM800

From page 3:

This document presents the AT command of base station location operation and application
examples. This document can apply to SIM800 series modules, but this function needs special
module and FW to be supported.

From what you say I guess that you don't have the special module & firmware?

Have you considered the SIM808? GPRS & GPS in one module?

thanks for response !
i heard from someone else, that we need to update firmware
but my commands runs on this SIM800L with OK result !
now the question is which version must be used for AT+CLBS ?
and how can i get firmware programs ?

Have you considered the SIM808? GPRS & GPS in one module?

yes, its a complete module ! and very expensive in Iran :frowning:

so the cheapest module is SIM800L until this day ...

i think some operators in Iran dont allows the users to access this services, so this commands dont return

any good values - im testing again ...

my currently firmware is 1418B04SIM800L24
and i found 1308B09SIM800L16 and 1308B04SIM800L16 on simcom.ee website (sim800l directory)
so which is the newer ? (i think my module is updated)

My interpretation of the text I quoted in reply #4 is that it is not a standard feature, and has to be installed (to order) when the chip is originally programmed.
