Parameter 

 

2.9. AT+QGPSXTRADATA    Inject a gpsOneXTRA Data File 

 

This  command  can  be  used  to  inject  a  gpsOneXTRA  assistance  data  file  to  GNSS  engine.  Before 

operating  this  command,  customers  must  enable  gpsOneXTRA,  store  the  valid  gpsOneXTRA  data  file 

into RAM or UFS (RAM is recommended) of the mudule and inject gpsOneXTRA time to GNSS engine. 

After operating this command successfully, gpsOneXTRA data file can be deleted from RAM or UFS, and 

customers can query whether the gpsOneXTRA data is injected successfully via 

AT+QGPSXTRADATA?
