Production Information
Data batching is disabled by default. To utilize this feature, the batching operation must be enabled
and the buffer size must be set. It is also possible to set up a PIO as a flag to indicate when the buffer
is close to filling up.
☞
The buffer size or the level of detail for the buffered data must not be changed while the receiver
already has some data in the buffer. The previous data in the buffer must be retrieved before
making any adjustments to the buffering.
Retrieval of the buffered data may take longer that one navigation cycle. E.g. retrieving a buffer of 300
position fixes over UART at 115200 baud takes slightly over 3 seconds. (This is longer than
300*108*10/115200 = 2.8 seconds, because the messages are not transferred gap-free. There may
be occasional gaps of up to 10 milliseconds.) If new position fixes arrive during retrieval operation, the
new data will not be included in the currently ongoing retrieval operation, but it will be available for a
new retrieval operation. See the u-blox 8 / M8 Receiver Description including Protocol Specification
for more information.
