• Into a file on the cellular module: A file with GNSS data can be accessed via +ULSTFILE command. The file

name is automatically chosen by the cellular module as a unique ID based on date and time or a further

incremental number (e.g. "GPS_200910061500" or "GPS_20091006_001" according to the used cellular

module). When the files size reaches 500 kB the file is closed and no more data is saved. It is possible to

save further data by restarting the GNSS (this will create a new file)

It is possible to send GNSS data to multiple destinations at the same time by summing the <GNSS_I/O_

configuration> values of each required destinations (e.g. if AT+UGPRF=6 the data will be sent on multiplexer

and stored in a file in the file system).

The messages to be output by the u-blox GNSS receiver need to be activated separately with UBX-CFG-MSG

configuration messages according to the GNSS Receiver Protocol Specification.

It is not possible to select the GNSS data flow to and from USB (or alternatively AUX UART) and multiplexer

concurrently.

The configuration of the GNSS profile must be performed only when GNSS is switched off, otherwise an

error result code will be displayed.

22.4.3Defined values

Parameter Type Description

<GNSS_IO_

configuration>

Number

• 0 (default value and factory-programmed value): no data flow to multiplexer, file or

IP address

• 1: GNSS data flow to and from USB (or alternatively AUX UART)

• 2: GNSS data flow to and from multiplexer

• 4: GNSS data flow saved to file

• 8: GNSS data flow over the air to an Internet host

• 16: GNSS data ready function

• 32: GNSS RTC sharing function

• 64: reserved

• 128: reset the GNSS after the GNSS power on (see AT+UGPS command description)

• 256: use the auxiliary GNSS receiver instead of the default one. If the feature is not

provided then an error result code will be displayed

<IP port> Number IP port of the server where the GNSS data are sent (default value and factory-

programmed value: 0). If GNSS data flow over the air is enabled the parameter is

mandatory otherwise is forbidden.

<server address

string>

String Address string of the server where the GNSS data are sent (default value and factory-

programmed value: ""). If GNSS data flow over the air is enabled the parameter is

mandatory otherwise is forbidden. The address could be provided in both URL or IP

format and the maximum length of the string is 47 characters.
