Detailed Description

Macro Definition Documentation

#define U_HARDWARE_GPS_CAPABILITY_SCHEDULING   0x0000001

Flags for the gps_set_capabilities callback.

GPS HAL schedules fixes for U_HARDWARE_GPS_POSITION_RECURRENCE_PERIODIC mode. If this is not set, then the framework will use 1000ms for min_interval and will start and call start() and stop() to schedule the GPS.

Definition at line 64 of file gps.h.

#define U_HARDWARE_GPS_MAX_SVS   32

Maximum number of SVs for u_hardware_gps_sv_status_callback().

Definition at line 37 of file gps.h.

#define U_HARDWARE_GPS_NI_SHORT_STRING_MAXLEN   256

String length constants

Definition at line 111 of file gps.h.
