# GPS NMEA plugin {#gpsnmea_plugin}
Version: @PROJECT_VERSION@
This plugin uses NMEA-compatible devices to provide location information to AMB.
To enable the GPS NMEA plugin, run cmake and enable the gpsnmea_plugin option:
cmake -Dgpsnmea_plugin=On ..
To use the Database plugin, add the following to the "sources" array in /etc/ambd/config:
~~~~~~~~~~~~~{.json}
{
"name" : "gpsnmea",
"path" : "@PLUGIN_INSTALL_PATH@/gpsnmea.so",
"device" : "/dev/ttyUSB0",
"baudrate" : "4800",
"bluetoothAdapter" : "00:00:00:00:00:00"
}
~~~~~~~~~~~~~
## Configuration Key Definitions:
"name"
name of plugin. This key is not used by the plugin at this moment.
"path"
path to plugin on the filesystem.
"device"
gps device. This must be a serial device. It can also be a bluetooth address.
Default: none
"baudrate"
Baudrate for serial devices : 2400,4800,9600,19200 or 38400.
Default: 9600
"bluetoothAdapter"
bluetooth adapter to use. This is only used if "device" is also a bluetooth device.
If left blank, the system default adapter will be used.
Default: none
## AMB Properties:
GpsTime
Timestamp in seconds from unix epoc (UTC) parsed from the NMEA output.
Type: double
Access: readonly
GpsSpeed
Speed as reported by GPS
Type: UInt16
Access: readonly
GpsFix
Fix status.
~~~~~~~~~~~~(.cpp}
enum FixType {
NoFix = 1,
Fix2D = 2,
Fix3D = 3
};
~~~~~~~~~~~~
Type: int
Access: readonly
GpsSatsUsed {#GpsSatsUsed}
How many satellites are being used in the fix
Type: UInt16
Access: readonly
GpsNmea
