Hi, the L26-DR GNSS Protocol Specification says, for example:
This command configures the Assisted GPS. The setting can only take effect by issuing the saving
command (i.e. $PSTMSAVEPAR) and, then, resetting the system (through $PSTMSRR). Once saved,
the configurations will persist even after a power cycling.
If no error occurs, the following message will be returned: $PSTMCFGAGPSOK*
In case of errors, this error message is returned: $PSTMCFGAGPSERROR*
so, when do we receive these messages of ERROR or OK, after or before resetting the module?
