GPS NMEA plugin

Version: 0.14.803

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:

{
    "name" : "gpsnmea",
    "path" : "/usr/lib/automotive-message-broker/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
