Timeout – Specifies the amount of data in terms of time (milliseconds) to return in response to a
HTTP GET request. The Time Interval refers to the “Age” of the received NMEA data. Each
record is tagged with a time stamp. Data is retained in the internal buffer until its “Age” exceed the
interval and then it is discarded. This allows multiple HPPT clients to issue GET requests and all see
“current data”
•
Threshold - Specifies the amount of data in terms of Bytes (value * 10) to return in response to a
HTTP GET request. Data is held in the internal buffer till it exceeds the Threshold value and then it
is discarded. Each HTTP GET request returns the amount of data specified by the Threshold value
times 10.
The Timeout and Threshold values work together in deciding how data is returned in response to a GET
request. Both conditions are applied to the request. For Timeout to have priority, the threshold must be set
to the minimum (100 = 1K bytes). Conversely, for Threshold to have priority, the Timeout must be set to
the minimum (1 millisecond).
