I am using AT+GNSSCONF command as well as the POLTE commands. I think it is related to the new firmware. I update the firmware to latest(HL7800 FW from Sierra Wireless), But bootloader COM port is not responding after some initial messages .
“AT+SWITRACEMODE=Customer” changed with “AT+SWITRACEMODE=CUSTOMER” and its worked.POLTE function configured and location data getting on my device.
Thanks for your time and support.
