 define the driver's properties to the client. Usually, only a minimum set of properties are defined to the client in this function if the device is in disconnected state. Those properties should be enough to enable the client to establish a connection to the device. In addition to CONNECT/DISCONNECT, such properties may include port name, IP address, etc. You should check if the device is already connected, and if this is true, then you must define the remainder of the the properties to the client in this function. Otherwise, the remainder of the driver's properties are defined to the client in updateProperties() function which is called when a client connects/disconnects from a device. More...

void setDynamicPropertiesBehavior (bool defineEnabled, bool deleteEnabled)
 setDynamicPropertiesBehavior controls handling of dynamic properties. Dyanmic properties are those generated from an external skeleton XML file. By default all properties, including dynamic properties, are defined to the client in ISGetProperties(). Furthermore, when ┼▒deleteProperty(properyName) is called, the dynamic property is deleted by default, and can only be restored by calling buildSkeleton(filename) again. However, it is sometimes desirable to skip the definition of the dynamic properties on startup and delegate this task to the child class. To control this behavior, set enabled to false. More...

Detailed Description

Class to provide general functionality of a GPS device.

The INDI::GPS provides a simple interface for GPS devices. It reports time in INDI standard property TIME_UTC. Location is reported in INDI standard property GEOGRAPHIC_COORD Only one function is called by the INDI framework to update GPS data (updateGPS()). If the data is valid, it is sent to the client. If GPS data is not ready yet, updateGPS will be called every second until the data becomes available and then INDI sends the data to the client.

updateGPS() is called upon successful connection and whenever the client requests a data refresh.

IPState INDI::GPS::updateGPS ( )
protectedvirtual

updateGPS Retrieve Location & Time from GPS. Update LocationNP & TimeTP properties (value and state) without sending them to the client (i.e. IDSetXXX).

Returns
Return overall state. The state should be IPS_OK if data is valid. IPS_BUSY if GPS fix is in progress. IPS_ALERT is there is an error. The clients will only accept values with IPS_OK state.

Reimplemented in GPSSimulator.

bool INDI::GPS::updateProperties ( )
virtual

updateProperties is called whenever there is a change in the CONNECTION status of the driver. This will enable the driver to react to changes of switching ON/OFF a device. For example, a driver may only define a set of properties after a device is connected, but not before.
