how can i factory reset module?
Per Quectel_LC29H_SeriesLC79HAL_GNSS_Protocol_Specification_V1.2.pdf which is available in the downloads section of quectel.com, the command you want to send is $PQTMRESTOREPAR (or with a checksum: $PQTMRESTOREPAR*13 ).
Hi Reziko and Luke,
$PAIR007*3D → Full cold start will performs a cold start and clears system and user configurations($PAIRxxx configurations) at the start, i.e., resets the module to its factory settings.
$PQTMRESTOREPAR*13 → Restores all parameters set via $PQTM commands to default values. And please reset the module after executing this command.
Best regards.
