Parameter 

 

2.4. AT+QGPSEND    Turn off GNSS 

 

When GNSS is turned on and 

<fixcount> 

is 0, GNSS fixes position continuously. In this case, GNSS can 

be  turned  off  compulsorily  via 

AT+QGPSEND

. When 

<fixcount> 

is  non-zero,  GNSS  will  be  turned  off 

automatically if the parameter

 

reaches the specified value, and thus the command can be ignored.   

<gnssstate>           

GNSS state

 

 

0                    GNSS OFF 

 

1

                   

GNSS ON

 

<gnssmode>

 

   

GNSS working mode 

 

1                    Stand-alone 

 

2                    MS-based 

 

3                    MS-assisted 

 

4                    Speed-optimal 

<fixmaxtime>     

 

 

The  maximum  positioning  time  (unit:  s),  which  indicates  the  response  time  of 

GNSS receiver while measuring the GNSS pseudo range and the upper time limit 

of  GNSS  satellite  searching.  It  also  includes  the  time  for  demodulating  the 

ephemeris data and calculating the position. 

 

1-30-255      Maximum positioning time   

<fixmaxdist>           

Accuracy threshold of positioning. Unit: m. 

 

 

1-50-1000 

<fixcount>   

             

Number of attempts for positioning

 

                                        0

–1000        0  indicates  continuous  positioning.  Non-zero  values  indicate  the 

actual number of attempts for positioning.   

<fixrate>       

   

   

The interval time between the first and second time positioning. Unit: s.   

                                   

1

–65535 

<errcode>           

        Integer type. The error code of the operation. If it is  not 0, it is the type of error. 

  Please refer to 

Chapter 4

 for details. 

AT+QGPSEND    Turn off GNSS   

Test Command   

AT+QGPSEND=? 

Response 

OK 

Execution Command 

AT+QGPSEND 

Response 

OK 

 

If there is any error related to ME functionality:
