Gps Parser (Coming Soon); Power Saving - MTX -3G-JAVA series User Manual

The GPS receiver is connected to the EHS6 ASC1 port and NMEA data at 9600 bauds is present. JAVA
code needs to open the ACS1 port and collect all these protocols and parses to calculate latitude and
longitude positions.
There are also two signals available to control the RF card:

RESET_GPS: active low, driven by GPIO12_P13 of the IO extender (see section 4.4.5). It allows
the RF module to be reset.

DISABLE_GPS: active low, driven by GPIO11_P12 of the IO extender (see
allows the RF module to be powered off.
To help all customers, Matrix Electronica provides "as is" (without further technical support,
warranties, etc.) PARSER source code to improve the time to market in JAVA developing code.
4.12.3 GPS Parser (coming soon)
Matrix Electronica provides MTXParser3G for developing purposes at no cost.
MTXParser3G is JAVA source code which basically handles the GPS unit installed on the internal
module and translates this into useful information such as positioning, as well as carrying out other
useful features like:

Obtaining GPS positioning in the same format as XT65

A function to activate/deactivate AutoPowerON feature.

A function to activate/deactivate/refresh the Hardware Watchdog feature.

A function to read X,Y,Z acceleration values.

A function to configure MTX‐3G‐JAVA‐GPS and power up the alarm: after switching off, the
modem will power UP when one axis (X, Y, Z) reaches the trigger acceleration value. Useful
to save battery power consumption.

A function to assist GPS (AGPS). Please ask gsmsupport@matrix.es

A function to switch ON/OFF secondary red LED for user purposes.
MTXParser3G can be used as a library/example. We supply this code "as is": this means that there
will be no documentation, no further support will be provided and no warranties will be given
regarding functionality. Matrix has tested it and uses it for internal purposes andcustomer support. It
is not commercial software/code.
Please ask gsmsupport@matrix.es to obtain a free copy.
4.12.4 Power saving
Power saving can be enabled on the GSM part (using the AT+CFUN function). On the GPS receiver it is
possible to use a special NMEA command. For more information on the AT command AT+CFUN, see
the AT command manual.
For more information about the NMEA internal GPS module please ask gsmsupport@matrix.es
