Detailed Description

Represents the standard GPS interface.

Field Documentation

void(* cleanup)(void)

Closes the interface.

Definition at line 806 of file gps.h .

void(* delete_aiding_data)( GpsAidingData flags)

Specifies that the next call to start will not use the information defined in the flags. GPS_DELETE_ALL is passed for a cold start.

Definition at line 824 of file gps.h .

const void*(* get_extension)(const char *name)

Get a pointer to extension information.

Definition at line 841 of file gps.h .

int(* init)( GpsCallbacks *callbacks)

Opens the interface and provides the callback routines to the implementation of this interface.

Definition at line 797 of file gps.h .

int(* inject_location)(double latitude, double longitude, float accuracy)

Injects current location from another location provider (typically cell ID). Latitude and longitude are measured in degrees expected accuracy is measured in meters

Definition at line 817 of file gps.h .

int(* inject_time)( GpsUtcTime time, int64_t timeReference, int uncertainty)

Injects the current time.

Definition at line 809 of file gps.h .

int(* set_position_mode)( GpsPositionMode mode, GpsPositionRecurrence recurrence, uint32_t min_interval, uint32_t preferred_accuracy, uint32_t preferred_time)

min_interval represents the time between fixes in milliseconds. preferred_accuracy represents the requested fix accuracy in meters. preferred_time represents the requested time to first fix in milliseconds.

'mode' parameter should be one of GPS_POSITION_MODE_MS_BASED or GPS_POSITION_MODE_STANDALONE. It is allowed by the platform (and it is recommended) to fallback to GPS_POSITION_MODE_MS_BASED if GPS_POSITION_MODE_MS_ASSISTED is passed in, and GPS_POSITION_MODE_MS_BASED is supported.

Definition at line 837 of file gps.h .

size_t size

set to sizeof(GpsInterface)

Definition at line 792 of file gps.h .

int(* start)(void)

Starts navigating.

Definition at line 800 of file gps.h .

int(* stop)(void)

Stops navigating.

Definition at line 803 of file gps.h .
