Access Geolocation data from MC8795 GPS

This is how you configure the RouterBoard (RB411U/RB411UHR) to get GPS data through MC87xx modems.

To enable GPS on RouterBoard through USB port, you need to configure the router as described below:

/system gps set enable=yes port=port channel=channel

Example:

/system gps set enable=yes port=usb2 channel=2

Where channel=2 is NMEA channel assigned for GPS data.

The data received from GPS channel can be accessed with following command:

system gps monitor

you will also be required to enable GPS on MC8795V that can be done with following AT command

AT!GPSENABLE=1

Other useful AT commands regarding GPS on MC87xx modems

AT!GPSSTATUS ?

AT!GPSFIX=<fixType>, <maxTime>, <maxDist>

where

<fixType> (Type of fix to establish):

• 1 = Standalone (not supported by a mobile station)

• 2 = MS-based only

• 3 = MS-assisted only

<maxTime> (Maximum time to wait for a position fix):

• Valid range: 0–255 seconds

<maxDist> (Requested accuracy of fix):

• Entered in decimal format

• Valid range: 0–0xFFFFFFEFmeters

• 0xFFFFFFF0: No preference

Example:

AT!GPSFIX=1, 15, 10 requests a standalone position fix to 10 meters accuracy. The

request will fail (timeout) if the modem cannot determine a position fix within 15

seconds.

I have attached the script that can be used to send GPS data from RouterBoard to an email address. I downloaded this script from here

you can refer to this link for more information (i-e how this script will work)
