Hello , I’ve been searching a lot about this ATC (AT+CLBS=1,1) but never seen any1 using it
at 1st I was getting ERROR for all CLBS commands with this firmware(1418B04SIM808M32) but then i upgraded the firmware to the version that has BT and EAT (1418B03SIM808M32_BT_EAT)
and I was getting responses from CLBS commands
everything works fine until last command which returns my location after doing triangulation from closest 3 cells (towers)
I got +CLBS: 3 ( 3 means NET ERROR from datasheet)
I talked to simcomm support and they replied me with this
www.c4a.com.cn can not work well now, maybe it can not be used in your city because the server doesn’t support the cell database of your city.
then they advised me to use other server
you can use AT+LBSCFG=1,3,”lbs-simcom.com:3002” to set new server and try AT+CLBS=1,1.
I used it and I got a different ERROR code +CLBS: 4 (4 means DNS error)
the thing I have no idea about these servers , I don’t know if they’re global servers or they work only for China
I’m trying to use this in Egypt using Vodafone Egypt sim card and I don’t know if there’s other LBS servers that can work in Egypt and can work with sim808
the only ATC that works for me is AT+CIPGSMLOC which is based on google servers but it only returns closest cell location not my location .
so any information about this will be very appreciated … I don’t know even know if this is related to country laws or service providers (like vodafone) laws
thanks in advance
