MC90 GNSS EPO Functionality

IoT Modules
1

Hello,

I am working with the module MC90( GPRS, GNSS, WiFi). I want to implement the EPO functionality in order to improve the TTF. I have followed the Application Note “MC60&MC90 GNSS AGPS Application Note”, but it seems that the module never downloads the EPO data.

The AT command sequence that I am using is the following:

AT
OK

+CFUN: 1
+CPIN: READY
Call Ready
SMS Ready

AT+CGCLASS=“CG”
OK

AT+CSCS=“GSM”
OK

AT+CGREG=2
OK
+CGREG: 1,“034D”,“55AF”

AT+QICSGP=1,“internet.easym2m.eu”
OK

AT+QGNSSTS?
+QGNSSTS: 1
OK

AT+QGNSSEPO=1
OK

AT+QGNSSEPO?
+QGNSSEPO: 1,2
OK

AT+QGNSSC=1
OK

AT+QGNSSCMD=0,"$PMTK60733"
OK
+QGNSSCMD: $PMTK707,0,0,0,0,0,0,0,0,02E

AT+QGNSSCMD=0,"$PMTK60733"
OK
+QGNSSCMD: $PMTK707,0,0,0,0,0,0,0,0,02E

AT+QGNSSCMD=0,"$PMTK60733"
OK
+QGNSSCMD: $PMTK707,0,0,0,0,0,0,0,0,02E

AT+QGNSSCMD=0,"$PMTK60733"
OK
+QGNSSCMD: $PMTK707,0,0,0,0,0,0,0,0,02E

AT+QGNSSCMD=0,"$PMTK60733"
OK
+QGNSSCMD: $PMTK707,0,0,0,0,0,0,0,0,02E

AT+QGNSSCMD=0,"$PMTK60733"
OK
+QGNSSCMD: $PMTK707,0,0,0,0,0,0,0,0,02E

AT+QGNSSCMD=0,"$PMTK60733"
OK
+QGNSSCMD: $PMTK707,0,0,0,0,0,0,0,0,02E

It is this functionality still available? Maybe the server where the data must be downloaded is down.

It will be much apreciate some feedback.

Best Regards,

Ferran

Hello,

I solved the problem. I forgot the following command before connecting to the 2G data network:

AT+QIFGCNT=2
OK

AT+CGREG=2
OK
+CGREG: 1,“034D”,“55AF”

Thanks,
