MYRIOTA_USER_API int GNSSFix

(

void

)

Perform a time and location fix from GNSS.

Updates real-time clock and latitude and longitude values.

Returns

0 if GNSS fix was correctly obtained and -1 otherwise.

HasValidGNSSFix()

MYRIOTA_USER_API bool HasValidGNSSFix

(

void

)

Check if the system has a valid GNSS fix.

Returns

true if a valid GNSS fix is available, false otherwise.

LocationGet()

MYRIOTA_USER_API void LocationGet	(	int32_t *	Latitude,
		int32_t *	Longitude,
		time_t *	TimeStamp
	)

Get the last recorded location and timestamp.

Parameters

Latitude[out]	Pointer to store the latitude in degrees multiplied by 1e7.
Longitude[out]	Pointer to store the longitude in degrees multiplied by 1e7.
TimeStamp[out]	Pointer to store the timestamp of the last fix.

LocationSet()

MYRIOTA_USER_API void LocationSet	(	int32_t	Latitude,
		int32_t	Longitude
	)

Set the location.

Location set may be overridden by GNSS fix if GNSS location fix is enabled.

Parameters

Latitude	Latitude in degrees multiplied by 1e7.
Longitude	Longitude in degrees multiplied by 1e7.

TimeGet()

(

void

)

Get the current epoch time.

Returns

The current epoch time.

TimeSet()

MYRIOTA_USER_API void TimeSet

(

time_t

Time

)

Set the current epoch time.

Parameters
