FlpBatchOptions Struct Reference
Options with the batching FLP APIs
Definition at line 258 of file fused_location.h .
FLP_BATCH_WAKEUP_ON_FIFO_FULL - If set the hardware will wake up the AP when the buffer is full. If not set, the hardware will drop the oldest location object.
FLP_BATCH_CALLBACK_ON_LOCATION_FIX - If set the location callback will be called every time there is a location fix. Its the responsibility of the upper layers (caller) to switch it off, if it knows that the AP might go to sleep. When this bit is on amidst a batching session, batching should continue while location fixes are reported in real time.
Other flags to be bitwised ORed in the future.

Maximum power in mW that the underlying implementation can use for this batching call. If max_power_allocation_mW is 0, only fixes that are generated at no additional cost of power shall be reported.

Frequency with which location needs to be batched in nano seconds.
Definition at line 290 of file fused_location.h .
The smallest displacement between reported locations in meters.
If set to 0, then you should report locations at the requested interval even if the device is stationary. If positive, you can use this parameter as a hint to save power (e.g. throttling location period if the user hasn't traveled close to the displacement threshold). Even small positive values can be interpreted to mean that you don't have to compute location when the device is stationary.
There is no need to filter location delivery based on this parameter. Locations can be delivered even if they have a displacement smaller than requested. This parameter can safely be ignored at the cost of potential power savings.
