AT^SBNW command fails with INTERNAL ERROR. | Telit Cinterion IoT Developer Community

Hi,

We have one customized board with a PLS8-X modem as a Cellular modem. We are using this modem to establish 4G connectivity and GPS. Both GPS and 4G cellular connectivity is working as expected.

However to improve GPS accuracy and reduce GPS fix time. We are trying to load the Xtra.bin file.  We have preformed AT commands in the sequence as pre AT command guide. However AT^SBNW="agps",59716 failed with Internal error.  Please refer below AT command output for reference.

AT
OK
AT+CCLK="20/02/21,09:51:00"
OK
AT^SGPSC="Engine","0"
^SGPSC: "Engine","0"

OK
AT^SBNW=agps,-1

CONNECT

AGPS READY: RESET GPS ENGINE AND DELETE XTRA FILE...

AGPS: END OK

OK
AT^SBNW="agps",59716
CONNECT

AGPS READY: SEND FILE ...

AGPS: INTERNAL ERROR

+CME ERROR: operation failed

I have downloaded Xtra file from URL http://xtrapath4.izatcloud.net/xtra2.bin. As URL in the AT command is not working as per https://iot-developer.thalesgroup.com/threads/gps-time-info-error.

Please suggest any solution or alternate way to do this. Apart from that, anybody aware of the error "AGPS: INTERNAL ERROR"  as do not have much information regarding this in AT command guide.  Please share your experience if you have observed the same in the past.

Thanks & Regards,
